Abstract This paper concerns the spatial and intensity transformations that are required to adjust for confounding effects of subject movement during functional MRI (fMRI) activation studies. An approach is presented models, removes, movement‐related artifacts from fMRI time‐series. predicated on observation extant even after perfect realignment. Movement‐related can be divided into those a function position object in frame reference scanner due previous scans. second component depends...
Watching a speaker’s lips during face-to-face conversation (lipreading) markedly improves speech perception, particularly in noisy conditions. With functional magnetic resonance imaging it was found that these linguistic visual cues are sufficient to activate auditory cortex normal hearing individuals the absence of sounds. Two further experiments suggest cortical areas not engaged when an individual is viewing nonlinguistic facial movements but appear be activated by silent meaningless...
OBJECTIVE: Functional magnetic resonance imaging (MRI) was used to investigate the hypothesis that attention deficit hyperactivity disorder (ADHD) is associated with a dysfunction of prefrontal brain regions during motor response inhibition and timing. METHOD: Generic activation seven adolescent boys ADHD compared nine comparison subjects equivalent in sex, age, IQ while they were performing stop task, requiring planned response, timing sensory cue. RESULTS: The hyperactive adolescents...
Neuropsychological studies report more impaired responses to facial expressions of fear than disgust in people with amygdala lesions, and vice versa Huntington's disease. Experiments using functional magnetic resonance imaging (fMRI) have confirmed the role response fearful faces implicated anterior insula disgust. We used fMRI extend these perception from both vocal expressions. Consistent neuropsychological findings, types stimuli activated amygdala. Facial caudate-putamen; did not...
Although high-functioning individuals with autistic disorder (i.e. autism and Asperger syndrome) are of normal intelligence, they have life-long abnormalities in social communication emotional behaviour. However, the biological basis difficulties is poorly understood. Facial expressions help shape behaviour, we investigated if people show neurobiological differences from controls when processing facial expressions. We used functional MRI to investigate brain activity nine adults (mean age ±...
<h3>Aim</h3> To evaluate the association between serum levels of complement component (C) 3, C4 and C1q visual field (VF) loss in patients with primary angle closure glaucoma (PACG). <h3>Methods</h3> In this prospective cohort study, a total 308 PACG were included. The followed up every 6 months (at least 2 years), clinical examination VF testing. Based on their sex age, subjects stratified into male female subgroups, by age at <60 ≥60 years per subgroup. <h3>Results</h3> One hundred...
<h3>Background</h3> Depression is associated with interpersonal difficulties related to abnormalities in affective facial processing. <h3>Objectives</h3> To map brain systems activated by sad affect processing patients depression and identify functional correlates of antidepressant treatment symptomatic response. <h3>Design</h3> Two groups underwent scanning twice using magnetic resonance imaging (fMRI) during an 8-week period. The event-related fMRI paradigm entailed incidental recognition...
Abstract Two questions arising In the analysis of functional magnetic resonance imaging (fMRI) data acquired during periodic sensory stimulation are: i) how to measure experimentally determined effect in fMRI time series; and ii) decide whether an apparent is significant Our approach first fit a series regression model, including sine cosine terms at (fundamental) frequency experimental stimulation, by pseudogeneralized least squares (PGLS) each pixel image. Sinusoidal modeling takes account...
Perceptions of speech in the absence an auditory stimulus (auditory verbal hallucinations) are a cardinal feature schizophrenia. Functional neuroimaging provides powerful means measuring neural activity during hallucinations, but results from previous studies have been inconsistent. This may reflect acquisition small numbers images each subject and confounding effects patients actively signaling when hallucinations occur.We examined 6 with schizophrenia who were experiencing frequent using...
Abstract Increasing evidence recognizes Alzheimer's disease (AD) as a multifactorial and heterogeneous with multiple contributors to its pathophysiology, including vascular dysfunction. The recently updated AD Research Framework put forth by the National Institute on Aging–Alzheimer's Association describes biomarker‐based pathologic definition of focused amyloid, tau, neuronal injury. In response this article, here we first discussed that dysfunction is an important early event in...
