The recognition of facial identity and expression are distinct tasks, with current models hypothesizing anatomic segregation of processing within a face-processing network. Using fMRI adaptation and a region-of-interest approach, we assessed how the perception of identity and expression changes in morphed stimuli affected the signal within this network, by(More)
To perform a saccadic response to a visual stimulus, a 'sensorimotor transformation' is required (i.e., transforming stimulus location into a motor command). Where in the brain is this accomplished? While previous monkey neurophysiology and human fMRI studies examined either parietal cortex or frontal eye field, we studied both of these regions(More)
BACKGROUND Horizontal canal benign paroxysmal positional vertigo is characterized by horizontal direction-changing nystagmus induced by lateral head turning in supine position. According to Ewald's second law, the direction of head turning that creates a stronger response represents the affected side in geotropic nystagmus and the healthy side in(More)
BACKGROUND The K variant of butyrylcholinesterase (BCHE-K) exhibits a reduced acetylcholine-hydrolyzing capacity; so the clinical response to rivastigmine may differ in Alzheimer's disease (AD) patients with the BCHE-K gene. OBJECTIVE To investigate the clinical response to rivastigmine transdermal patch monotherapy or memantine plus rivastigmine(More)
Despite a few case reports over the last 60 years, little progress has been made in defining the phenotype, genotype and pathophysiological mechanisms involved in pigmentary orthochromatic leukodystrophy (POLD). Furthermore, there is currently no data available regarding MRI in patients in the relatively early stages of POLD. Here, we present a 37 year old(More)
OBJECTIVE Assessing and monitoring care and service using clinical indicators (CIs) can allow the measurement of and lead to improvements in the quality of care. However, the management and maintenance of CI data has been shown to be difficult because the data are usually collected and provided manually. In this study, for the purpose of efficient managing(More)
The fusiform gyrus is involved pathologically at an early stage of the amnestic form of mild cognitive impairment (aMCI), and is also known to be involved in the perceptual stage of face processing. We assessed face perception in patients with aMCI to determine if this cognitive skill was impaired. We compared 12 individuals (4 men) with aMCI and 12 age-(More)
AIMS In order to evaluate the metabolite changes of both anterior and posterior cingulate gyri during the progression of Alzheimer's disease (AD) pathology, a 3-tesla MR spectroscopy study was performed. METHODS Thirty-six patients with AD, 19 patients with amnestic mild cognitive impairment (aMCI), and 23 cognitively normal (CN) subjects were recruited.(More)
BACKGROUND Highly educated participants with normal cognition show lower incidence of Alzheimer's disease (AD) than poorly educated participants, whereas longitudinal studies involving AD have reported that higher education is associated with more rapid cognitive decline. We aimed to evaluate whether highly educated amnestic mild cognitive impairment (aMCI)(More)
The exact functional correlation of each hemisphere's posterior cingulate gyrus with the symptoms of Alzheimer's disease (AD) remains unknown. We attempted to evaluate the relationship between metabolite ratios in each hemisphere's posterior cingulate gyrus and cognitive deficits, using multivoxel magnetic resonance spectroscopy (MRS). We recruited 23(More)
