Materials and Methods Subjects Cerebral magnetic resonance examin

Materials and Methods Subjects Cerebral magnetic resonance examinations were performed for clinical purpose at our institution after selection of patients by the multidisciplinary fetal medical team. The indications of the fetal magnetic resonance imaging (MRI) explorations were pregnancies at risk of brain damage, suspicion of Inhibitors,research,lifescience,medical brain malformation on ultrasound scans, and presence of maternal and/or family

history of brain development disorders. Gestational age was determined by a previous sonography at 12 postovulatory weeks. Fetuses were selected when conventional MRI examinations were normal based on the report of a neuroradiologist expert in fetal MRI (NG) (absence of anatomical malformation, absence of WM or gray matter lesions) and when they were considered normal at birth by pediatric neurologist. Of the 141 brain fetus DTI acquisitions, 61 fulfilled these criteria. Imaging in the presence of subject motion has been an Inhibitors,research,lifescience,medical ongoing challenge for MRI, especially for motion sensitive examinations such as DTI. In utero fetal DTI is an extreme case vulnerable to the mother’s respiration and fetal motion artifacts. Consequently, among 61 normal cerebral fetal MRI with DTI sequence, only 17 (28%) were selected for the study based on Inhibitors,research,lifescience,medical the absence

of motion corruption on coronal, sagittal, and axial views of b = 0 images evaluated by two independent readers (EZ, NG) and the Imatinib chemical structure sufficient quality of the FA color-coded Inhibitors,research,lifescience,medical directionality map (color coherence of the major bundles)

and ADC maps (Fig. 1). Discordant cases were finally rejected by consensus. The mean gestational age was 32 ± 4 weeks of gestation (range, 23–38 weeks). The cohort was constituted by fetuses at gestation ages of 23 GW(1), 24 GW(1), 27 GW(1), 28 GW(2), 30 GW(1), 32 GW(1), 33 GW(3), 34 GW(2), 35 GW(2), 36 GW(1), 37 GW(1), and 38 GW(1).

Conventional fetal MRI were acquired using T2-weighted single-shot sequences (HASTE, TE/TR: 137 ms/1680 ms; BW 220 Hz/pixel, 21 contiguous slices, 3.5 mm thickness, matrix: 358 × 512, FOV: 380 mm) acquired in three orthogonal planes oriented along the fetal brain, and both axial and coronal gradient echo T1-weighted sequence (Flash TE/TR: 3.3 ms/493 ms, BW 260 Hz/pixel, 19 slices, 4 mm thickness, matrix: 154 × 256, FOV: 350 mm).

The central barrier to home

care is, according to family

The central barrier to home

care is, according to family members, the preference of patients to be cared for by family members. Both professionals and family members indicate that the situation of the family is relevant. But while professionals indicate that they sometimes feel obstructed by, for instance, the cultural habits of the Turkish and Moroccan families and the less openly expressed personal preferences, family members emphasize Inhibitors,research,lifescience,medical that professionals should take such features into account. In addition, both professionals and family members agree that the information about and performance of the home care organizations are relevant factors. Family members indicated that proper information about the facilities of home care and good previous experiences with home care are major factors [16]. As for many Turkish and Moroccan families the GP is the principal source of information about home care, his referring performance can be crucial. But we just discovered in this study that GPs sometimes hesitate to refer to home care and that they agree significantly

less than nurses Inhibitors,research,lifescience,medical with statements that Turkish and Moroccan terminally ill patients are in great need of information, nursing and coaching given by home care organizations. One question to be raised is whether these check details findings are typical for the use and access of home care by terminally ill Turkish and Moroccan patients? Our findings correspond with the results Inhibitors,research,lifescience,medical of studies on the care for and needs of chronically ill elderly (not particularly in the terminal phase) with a Turkish background [21-23]. These studies also point in the direction that Turkish families want to take full responsibility Inhibitors,research,lifescience,medical for the care of their patient, and that professional home care is seldom used. These studies also found that particularly daughters assume more and more responsibility for the ill relative, and that bedridden elderly

often suffer because of the lack of professional care. Another question to be raised is whether it is justified that we Inhibitors,research,lifescience,medical studied the Turkish and Moroccan target groups jointly. We recognize that there are important cultural Amisulpride differences between the groups of Turkish and Moroccan migrants and their families, e.g. related to their different socio-geographical roots and different languages. However, we considered it worthwhile to include both groups in our study, because both groups have some relevant common features: in the Netherlands they have a largely comparable immigration history, they are Muslims in a Christian society, they often have close family and community relations, their socioeconomic situation is not favorable and their self reported health status is often poor [11,12]. On the basis of our previous study among relatives, we had the impression that more Turkish informal carers than Moroccans had to combine their caring for the terminally ill patient with other duties like childrearing, and a formal job.

Riluzole, a tedrotoxin-sensitive sodium channel blocker, is the o

Riluzole, a tedrotoxin-sensitive sodium channel blocker, is the only existing treatment and can delay disease progression with few months [8,9]. Non-invasive ventilation (NIV) can relieve dyspnoea, increase quality of life, and improve survival outcomes; particularly among ALS

patients without severe bulbar symptoms [10-13]. Several guidelines currently recommend the use of NIV as palliative treatment for ALS [4-7]. The effect of age has not been addressed in previous studies assessing the impact of NIV on survival outcomes [10,12,13]. Therefore, the effect of NIV on survival was compared Inhibitors,research,lifescience,medical in patients aged 65 years and older of age at the time of diagnosis, designated as Group 1 and Group 2 respectively. Based on previous studies

[10,12,13] it was hypothesised that NIV users would experience improved survival outcomes in both age groups when compared with patients who declined NIV were unable to tolerate treatment. Methods Design A registry-based retrospective cohort study was undertaken, Inhibitors,research,lifescience,medical covering the period January 2001 to June 2012, on 91 patients fulfilling the El Escorial World Federation Inhibitors,research,lifescience,medical criteria for probable or HA-1077 cell line definitive ALS [14]. Once a positive diagnosis was made by a neurologist, patients were referred to a specialist to evaluate their suitability for NIV. All patients were systematically followed up at intervals of 3 to 6 months, until the date of death or June 1 2012, when the follow-up period ended. NIV and other palliative

treatments were offered to all the patients. Six patients showed survival Inhibitors,research,lifescience,medical over ten years and this finding was quite consistent with earlier studies which have been shown that 5 to 10% of ALS patients will survive over ten years [15]. Two of these six patients (age 54 and 79 years) used NIV while the rest of the patients (age range 49 – 63 years) refused NIV. Because of possible bias resulting from small number of patients with slow disease progression, these cases were excluded. In addition, one patient Inhibitors,research,lifescience,medical was excluded because of commencement of GBA3 NIV before the time of diagnosis for treatment of respiratory insufficiency due to pulmonary embolism. Because of current clinical trials legislation in Finland, patient consent is not required for register studies. Patient consent was therefore not obtained in this instance. The study protocol was approved by the Ethics Committee of the Hospital District of South-West Finland. Altogether, 84 patients were included and retrospectively divided into two groups based on their age at the time of the diagnosis: Group 1 (age≤65 years) and Group 2 (age>65 years). Both groups were then subdivided further based on patients´ ability to tolerate the NIV. These were designated as the NIV Group and the Conventional Group, as presented in Figure 1. Figure 1 Flowchart of the study.

40 Additionally, hoarding is more frequent in the first-degree relatives of hoarding probands, and hoarding is associated with other biological and gender differences.31,33,37,68,71,138-141 Thus, with only a few interesting exceptions, the chromosomal regions discovered

in the genome-wide linkage studies of OCD as possibly harboring OCD-related genes are relevant only to OCD in general, without much attention to OCD diversity and heterogeneity, or Inhibitors,research,lifescience,medical with regard to other OCSDs. The same is true for those studies focusing on a single candidate gene. One other exception of possible future interest in regard to likely gene-related subgroupings is age of OCD onset.137 Common gene variants plus rare gene and genetic syndromes associated with OCD and OCD/Tourette syndrome subgroups and/or OCD-related disorders Uncommon chromosomal anomalies and both rare and common

gene variants have come under Inhibitors,research,lifescience,medical increasing scrutiny in OCD and OCD-related or OCD-comorbid disorders. Several uncommon chromosomal region abnormalities that are associated with multiple Inhibitors,research,lifescience,medical phenotypes have been found to include individuals with OCD. Thus, OCD diagnoses have been made in individuals with the 22q11 microdeletion syndrome (also known as Serotonin receptor antagonist drugs velocardiofacial syndrome).142-145 In one comprehensive study that used the YBOCS scale together with psychiatric interviews in evaluating a VCSF clinic sample, 33% received an OCD diagnosis.142 OCD has also been diagnosed in some individuals with the myoclonus dystonic syndrome related to chromosome 7q.146-149 In one study of Inhibitors,research,lifescience,medical three extended myoclonus dystonic syndrome families, OCD meeting direct interview-based DSM-FV criteria

was present in 25% (4/16) of symptomatic myoclonus dystonia syndrome carriers with the 7q21 haplotype, but in only 9% (1/11) of nonsymptomatic carriers and 0% (0/28) of the nonhaploytpe carriers.146 This is of special interest because its 7q21-q31 locus is near the chromosomal anomalies described in other individuals with OCD or Tourette syndrome but without the Inhibitors,research,lifescience,medical myoclonus dystonic syndrome who have anomalies in chromosome regions 7q31 and 7q35-36.150-152 Additionally, a family-based association study using markers in the 7q31 region demonstrated biased transmission of these marker alleles in individuals with comorbid Tourette syndrome, Cediranib (AZD2171) OCD, and ADHD.153 For the 22q11 and 7q variants, insufficient data exist for OCD, OCD spectrum disorders like other dystonias,154-157 and possibly related disorders like autism spectrum disorder to draw firm conclusions as to how these different disorders might be related. However, these findings from uncommon chromosomal regions and rare genes suggest distinct and different etiologies for an OCD phenotype that may represent a type of OCD spectrum disorder, ie, a genomic group of OCSDs.

Program evaluators have recognized the gap between the acquisitio

Program evaluators have recognized the gap between the acquisition of knowledge or skills and subsequent changes in attitudes and behavior [26]. In support of the social-cognitive theory of behavior change, a this website recent study of motivation, self-confidence and skill retention found that gains in these factors were dependent on the method and timing of CPR training

[27]. Therefore, an effective CPR refresher must address not only skill retention, but also confidence and behavioral intention to perform CPR. More research is required to examine the effectiveness of CPR refreshers on skill retention, confidence and motivation, as well as the appropriate Inhibitors,research,lifescience,medical format, timing and frequency Inhibitors,research,lifescience,medical of such refreshers. In order to be effective, CPR refreshers should be easily accessible, available at no or low cost, and likely to be reviewed by trainees in the general population. Thus, the most desirable format would be to deliver the content to a trainee’s home or office, rather than requiring the person to attend a session in a special location. New electronic means of communication have expanded the possibilities for delivering CPR refreshers to members of the general public who received training in CPR. Such an approach Inhibitors,research,lifescience,medical does not include renewed CPR practice, which is difficult to

arrange. Our basic assumption Inhibitors,research,lifescience,medical was that various electronic modalities can actively direct the attention of prior trainees to messages designed to help them in recalling correct CPR techniques. Specifically, electronic refreshers are hypothesized to aid in retaining CPR administration skills, confidence in performing CPR and intention to perform CPR when needed. General Inhibitors,research,lifescience,medical population access to and use of electronic communication is already quite extensive, especially among younger people, and is continually

increasing [28-32]. Studies have documented internet access among even more difficult to reach (e.g., low income) populations [33-35]. Based on these trends of increasing access to electronic and mobile communications, the novel CPR Rolziracetam refresher formats selected for this study were: online website, e-mail, and text messaging by cell phone. Recent studies have shown that such electronic communication formats can be effective in increasing confidence and motivation to engage in health promoting behaviors [36-39]. The present study conducted a randomized controlled trial (RCT) of four CPR refreshers – online website, e-mail, text messaging and a mailed brochure – to determine their efficacy in affecting skill retention, confidence in using CPR and intention to use CPR at a one year follow-up after initial CPR training. The first three refreshers, based on electronic communication, can be considered “novel” in that they are not typically used to refresh CPR knowledge and skills.

Most of these patients are Caucasians. selleck products Metabolite profiles were performed using

1H NMR and analyzed statistically using several approaches including partial least squares discriminant analysis (PLS-DA). A good model could be built based on the entire NMR spectrum as well as on only three metabolite biomarkers, and these results were internally Inhibitors,research,lifescience,medical cross-validated. This study is the first to identify good serum metabolite biomarkers by NMR to distinguish HCC patients from a population of patients with HCV and cirrhosis in the U.S. 2. Experimental Methods 2.1. Chemicals Deuterium oxide (D2O, 99.9% D) and sodium azide (NaN3) were purchased from Cambridge Isotope Laboratories, Inc. (Andover, MA). The sodium salt of trimethylsilylpropionic acid-d4 (TSP), used as the internal standard, was from Sigma-Aldrich (Milwaukee, WI). All chemical reagents were analytical grade and used without further purification. 2.2. Serum Sample Collection and Storage Human serum samples (n = 62) were obtained from the Indiana University/Lilly

tissue bank, and consisted of two cohorts: HCC Inhibitors,research,lifescience,medical patients (n = 40) with underlying HCV, and HCV patients (n = 22) without HCC. A summary of sample information can be seen in Table 1. Frozen samples were transported to Purdue University Inhibitors,research,lifescience,medical under dry ice and then kept at -80 °C until analysis. The study was approved by the Institutional Review Boards at both Purdue University and Indiana University School of Medicine. Table 1 Summary of demographic and clinical information Inhibitors,research,lifescience,medical for subjects recruited for the study. 2.3. Sample Preparation and Acquisition of NMR Spectra Samples were prepared by mixing 400 µL serum with 5µL sodium azide (0.01% w/v) and 130 μL D2O. The solution (530 µL) was then transferred to a 5-mm NMR tube.

A 60 μL, 0.5mM TSP solution contained in a capillary insert was used as an internal standard. For the 1D NMR experiments, the spectra were acquired at 298 K on a Bruker Avance-500 Inhibitors,research,lifescience,medical spectrometer equipped with a TXI gradient cryoprobe, using standard 1D NOESY and 1D CPMG (Carr-Purcell-Meiboom-Gill) pulse sequences, each coupled with water presaturation. For each spectrum, 128 transients were collected with 16k time domain data points and using a spectral very width of 6,000 Hz. All spectra were Fourier transformed using a 1.0 Hz exponential line broadening. Each acquired spectrum was then phased, baseline corrected and aligned with reference to alanine (δ=1.479 ppm) using Bruker Topspin 3.0 software. 2.4. Statistical Analysis After excluding the spectral region δ 4.7–5.2 ppm containing the residual water resonance, each spectrum was binned to 4096 points (bin size 0.003 ppm), and then normalized to the area of the TSP signal at 0.0 ppm. The spectral data from both the CPMG and NOESY experiments were initially mean centered and subjected to orthogonal-signal-corrected (OSC) partial least squares (PLS) analysis using Matlab (R2008a; Mathworks, Natick, MA) and the PLS Toolbox (version 4.

An example of an item from this scale is, “Depression is often associated with a hastened desire to die”. Responses are measured on a four-point selleck Likert scale ranging from ‘strongly disagree’ to ‘strongly agree’. 2. Views of depression. This questionnaire consists of 21 items and will be used to measure staff member’s attitudes towards depression and the provision of Inhibitors,research,lifescience,medical mental health care. It was constructed from items from a modified version of the

Depression Attitude Questionnaire [22] and items from a pool of attitude-based questions derived using the same process described above. An example of an item from this scale is, “It is important that carers spend time with patients discussing how they are coping psychologically”. Responses are measured on a five-point Likert scale ranging from ‘strongly disagree’ to ‘strongly agree’. 3. Self-efficacy in detecting and managing depression. This 16-item questionnaire was adapted to the palliative care setting

from a scale originally developed to assess the self-efficacy Inhibitors,research,lifescience,medical of care staff in working with depression in the aged care sector [17]. An example of an item from this scale is, “In knowing when it might be time to raise concerns about a patient who might be depressed, I feel…”. Responses are measured on a four-point Likert scale ranging from ‘not at all confident’ to ‘very confident’. 4. Barriers Inhibitors,research,lifescience,medical to detecting and managing depression. This 12-item questionnaire will be used to assess staff members’ perceived barriers to detecting Inhibitors,research,lifescience,medical depression and providing care for depressed patients and their family members. The items from this scale were constructed from a pool of items created by the researchers and based on the barriers to detection and Inhibitors,research,lifescience,medical management of depression identified in the literature review and needs analysis. An example of an item from this scale is, “The stigma associated

with depression makes it difficult to talk about such issues with patients and family members”. Responses are measured on a four-point Likert scale ranging from ‘strongly disagree’ to ‘strongly agree’. Semi-structured interviews will be conducted at the three Endonuclease month follow-up with groups of care staff who have participated in the training program to obtain their feedback on the program and how it may have impacted on their practices and level of knowledge, views, self-efficacy and perceived barriers towards working with depression among their patients. These interviews will supplement the data collected in the quantitative measures by gathering more in-depth information and providing a forum for staff to advise on aspects of the training program which they found particularly helpful or informative, aspects that may benefit from further refinement, or by providing other information that may not be captured in the measures.

62,63 Since then, not much has changed in the recommended light

62,63 Since then, not much has changed in the recommended light treatment regimen, except that light intensity can be as great as 10 000 lux,64 and perhaps 1 h per day is sufficient, as long as it is scheduled immediately upon awakening. Once treatment is satisfactory, the duration of light exposure can almost always be reduced.65 Several other studies have supported these findings, but some have not66,67: these studies were usually parallel-designed, so that patients themselves did not have the opportunity to compare light exposure at different times (which would have minimized the placebo component). In 1998, three independent research groups Inhibitors,research,lifescience,medical published large-N studies in which morning light was shown to

be more antidepressant than evening light thereby moving the field towards consensus about the superiority of morning light.45,68,69 However, superior efficacy of morning light does not necessarily prove the PSH, because it could be more Inhibitors,research,lifescience,medical antidepressant at this time for some reason other than causing

a phase advance. However, it has been shown that the antidepressant response to morning light does, in some circumstances, correlate with the amount of phase advance in the DLMO. This was first reported with respect to treatment group means,61 followed by an analysis70 of individual DLMOs and depression scores collected independently.36,63 More recently, this latter finding was essentially replicated Inhibitors,research,lifescience,medical Inhibitors,research,lifescience,medical using another data set.71 Further support of the PSH along these lines will be discussed below. It should also be noted that a very small subgroup of SAD patients appear to be cueing to dusk and should be treated with evening bright light; clinically, these patients

can be identified by a history of early morning awakening year round, going to bed much earlier in the Topoisomerase inhibitor winter.65 In any event, the earliest and most common use of the DLMO has been to assess the phase-shifting effects of light. Bright light has also been used to treat a number of other circadian phase disorders, such as advanced sleep phase syndrome (ASPS), delayed sleep phase syndrome (DSPS), jet Inhibitors,research,lifescience,medical lag, and shift work maladaptation (see below). The melatonin PRC The phase-shifting effects of melatonin are also Rolziracetam described by a PRC. The melatonin PRC is about 12 h out of phase with the light. PRC.13,44 Both PRCs are phase-locked to each other, as well as to the melatonin profile (Figure 2). As mentioned above, waketime is usually designated ZT 0. Sleep time is therefore usually ZT 16. In the melatonin PRC studies of sighted people, the baseline plasma DLMO10 was designated CT 14. It is also designated CT 14 in free-running blind people. We call this phase marker the MO in blind people. Saliva can also be used (at this time of the night, salivary melatonin levels are about one -third those of plasma).72 Measuring the MO in blind people provides a reference point to determine the phase of the endogenous circadian pacemaker and the melatonin PRC.

Sleep reciuiremeiits ‘Ihcsc gradually lessen throughout childhood

Sleep reciuiremeiits ‘Ihcsc gradually lessen throughout childhood until about the time of puberty, when the need for sleep might actually increase somewhat. This, combined with a physiological delay in the sleep phase at puberty (opposite to the sleep phase advance in the elderly), as well as

late-night social activities, sets the scene for potentially severe sleep deprivation and excessive daytime sleepiness (the delayed sleep phase syndrome, or DSPS) which readily leads to educational and social difficulties in adolescence. Pattern of occurrence of sleep behaviors and disorders ‘Ihis differs between children and adults. Some sleep disorders Inhibitors,research,lifescience,medical occur much more Inhibitors,research,lifescience,medical commonly in children and adolescents, notably bedtime settling and troublesome nightwaking in

young children (the result of not acquiring good sleep habits and ovcrdepcndence on parental attention). Adolescent DSPS has just been mentioned. Other examples include rhythmic movement disorders (such as head-banging), nocturnal enuresis, and arousal disorders seen mainly in prepubertal children. Interestingly, some sleep disorders previously thought to occur mainly or exclusively in adults are now recognized in children, eg., this website obstructive sleep apnea, restless legs syndrome,9 periodic limb movements in sleep,10 and even REM sleep behavior disorder Inhibitors,research,lifescience,medical (RED).11 Etiological factors In explaining the cause of sleep problems at any age, both physical and psychological possibilities (perhaps in combination) have to be considered. In children, as in adults, neurological, respiratory, metabolic, endocrine, genetic, medication, or other physical factors may have an influence. That said, parenting practices play a major part Inhibitors,research,lifescience,medical in many children’s sleep problems. Parental knowledge, attitudes,

and emotional state often determine whether a child’s sleep pattern is a problem or not. Some parents construe normal behavior as a problem; others do not seek help when they should, perhaps because they mistakenly think there is no treatment available. Clinical manifestations Inhibitors,research,lifescience,medical and associations Whereas obesity is a common feature of obstructive sleep apnea (OSA) in adults, enlarged tonsils and adenoids are usually responsible in children. Terminal deoxynucleotidyl transferase Although obesity is increasingly an important factor at all ages, only a minority of children with OSA are overweight and, indeed, ver}’ early onset may cause low body weight from failure to thrive. Adult OSA generally causes sleepiness and reduced activity. In contrast (as in other causes of excessive sleepiness such as narcolepsy), some sleepy children are abnormally active. This can lead to a diagnosis of attention-deficit hyperactivity disorder (ADHD) and inappropriate treatment with stimulant drugs. Misdiagnosis ‘Ihcrc is a risk that certain sleep disorders will be misdiagnosed at any age.

fMRI data acquisition and analysis fMRI data acquisition Function

fMRI data acquisition and analysis fMRI data acquisition Functional images were acquired on a 3T BRUKER MedSpec 30/100 system (Bruker Corporation, Billerica, MA), equipped with a standard birdcage head coil. Functional images were collected with a single shot gradient echo-planar imaging (EPI) sequence with the following parameters: echo time TE = 25 msec, flip angle 90°, repetition time TR = 2000 msec, acquisition bandwidth 100 kHz. Twenty-six axial slices were taken in an interleaved fashion (pixel matrix = 64 × 64 and in-plane resolution = 3 × 3 mm, resulting in a field of view of 19.2 cm, a slice thickness of 4 mm, and an

interslice gap Inhibitors,research,lifescience,medical of 1mm), oriented parallel to the bicommissural plane (AC-PC). The total number of functional scans collected per participant was 780 for the experimental conditions

and 233 for the FEF-L. Additionally, Inhibitors,research,lifescience,medical three-dimensional (3D) high-resolution whole brain images were acquired from each subject (MP-RAGE sequence, 160 slices, 1 mm thickness) in a separate session on a 3T Siemens MAGNETOM TIM Trio (Siemens AG, Munich and Berlin, Germany), used to align the functional data slices onto a 3D stereotactic coordinate reference system. fMRI data preprocessing All fMRI data analyses were carried out using the SPM8 software package (Wellcome Department of Imaging Neuroscience, London, U.K.) with Matlab 7 (Mathworks, Natick, MA). After EPI volumes were Inhibitors,research,lifescience,medical corrected for motion, distortion, and slice timing, they were realigned, unwarped, normalized to Inhibitors,research,lifescience,medical the Montreal Neurological Institute (MNI) template (3 × 3 × 3 mm resolution), and spatially smoothed (8 mm). fMRI data first-level analysis Each motion period (time between end of still period and beginning of target identification period, see above) was modeled as a boxcar

spanning the length of 6000 msec, convolved with the standard hemodynamic response function, representing activation Inhibitors,research,lifescience,medical during MOT and LUM, respectively. Accordingly, a design matrix was fitted with regressors for MOT and LUM. Trials that showed erroneous behavioral performance were modeled just as regular MOT and LUM trials, yet labeled as JUNK. JUNK and BASELINE (modeled as a boxcar spanning the duration of 4000 msec ITIs) entered the analysis as additional regressors. For first-level analysis, contrast images were computed combining the parameter estimates of the almost corresponding experimental conditions (MOT, LUM). For the FEF-L, a design matrix was fitted with regressors for FIX and SACC, each modeled as a boxcar with a duration of 15 s and convolved with the standard hemodynamic response function. Computing contrast images combining the parameter estimates of FIX and SACC, effects of the two regressors were compared to each other resulting in FEF-L activation. This was done on the group level due to the selleck circumstance that individual subjects showed large variations in activation strength.
