Exact timing is essential for functional MRI data analysis. Datasets are commonly measured using repeated 2D imaging methods, resulting in a temporal offset between slices. To compensate this difference, slice-timing correction (i.e. interpolation) has been used as an fMRI pre-processing step more than fifteen years. However, there ongoing debate about the effectiveness and applicability of method. This paper presents first elaborated analysis impact effect on simulated different paradigms...
Activity of the supplementary motor area may be inferred from movement-related potentials (MRPs) which are associated with preparation and execution voluntary, or internally determined movements. Supplementary activity abnormal in Parkinson's disease since its major input basal ganglia is disrupted. Investigation abnormalities movement deficits therefore reveal functions area. Movement-related sequential movements were investigated under various cueing conditions subjects age-matched...
A key aspect of higher cognitive function is the ability to switch rapidly and efficiently between alternative modes response where this appropriate behaviourally. Such suppression appears be highly dependent upon integrity prefrontal cortex, yet other cortical areas are likely necessary implement switching. Language switching in bilingual speakers a clear example task which required. Functional brain imaging studies have demonstrated parietal cortex activation during repeated language...
Abstract Current evidence suggests that attention deficit hyperactivity disorder (ADHD) involves dysfunction in wide functional networks of brain areas associated with and cognition. This study examines the structural integrity white‐matter neural pathways, which underpin these networks, connecting fronto‐striatal fronto‐parietal circuits, children ADHD. Fifteen right‐handed 8 to 18‐year‐old males ADHD‐combined type 15 right‐handed, age, verbal, performance IQ‐matched, healthy underwent...
Abstract We investigated the extent to which a common neural mechanism is involved in task set-switching and response withholding, factors that are frequently confounded taskswitching go/no-go paradigms. Subjects' brain activity was measured using event-related electrical potentials (ERPs) functional MRI (fMRI) neuroimaging separate studies same cognitive paradigm. Subjects made compatible left/right keypress responses arrow stimuli of 1000 msec duration; they switched every two trials...
Abstract The scientific study of compassion is burgeoning, however the putative neurophysiological markers programs which actively train distress tolerance, such as Compassionate Mind Training (CMT), are less well known. Herein we offer an integrative, multi-method approach investigated CMT at neural, physiological, self-report, and behavioural levels. Specifically, this first assessed participants’ neural responses when confronted with disappointments (e.g., rejection, failure) using two...
Recent studies have shown that perceiving the pain of others activates brain regions in observer associated with both somatosensory and affective-motivational aspects pain, principally involving anterior cingulate insula cortex. The degree these empathic neural responses is modulated by racial bias, such stronger activation elicited observing people same group compared another group. aim present study was to examine whether a more general social category, other than race, could similarly...
Thirst was induced by rapid i.v. infusion of hypertonic saline (0.51 M at 13.4 ml/min). Ten humans were neuroimaged positron-emission tomography (PET) and four functional MRI (fMRI). PET images made 25 min after beginning infusion, when the sensation thirst began to enter stream consciousness. The fMRI maximum rate increase occurred. results showed regional cerebral blood flow changes similar those delineated maximal. These loci involved phylogenetically ancient areas brain. activation in...
Individuals with autism spectrum disorders typically have normal visuospatial abilities but impaired executive functioning, particularly in related to working memory and attention. The aim of this study was elucidate the functioning frontoparietal networks underlying spatial processes during mental rotation persons disorders.Seven adolescent males IQ an disorder nine age- IQ-matched male comparison subjects underwent functional magnetic resonance imaging scans while performing a task.The...
A functional magnetic resonance imaging mental rotation paradigm was used to investigate the patterns of activation fronto-parietal brain areas in male adolescents with attention-deficit hyperactivity disorder, combined type (ADHD-CT) compared age-, gender-, handedness- and performance IQ-matched healthy controls. The ADHD-CT group had (a) decreased 'action-attentional' system (including Brodmann's (BA) 46, 39, 40) superior parietal (BA 7) middle frontal (BA10) (b) increased posterior...
