Functional brain imaging in apraxia.
BACKGROUND An extensive literature describes structural lesions in apraxia, but few studies have used functional neuroimaging. We used positron emission tomography (PET) to characterize relative cerebral glucose metabolism in a 65-year-old, right-handed woman with progressive decline in ability to manipulate objects, write, and articulate speech. OBJECTIVE To characterize functional brain org...
متن کاملAnalysis of Memory-Related Brain Activation Maps in Sleep-Depriveation using Functional Magnetic Resonance Imaging
Background and purpose: Insomnia is a common sleep disorder with negative consequences such as decreased quality of life. In this study, the effect of sleep deprivation on memory in both young and older adults was investigated using functional magnetic resonance imaging (fMRI). Materials and methods: In this retrospective study, fMRI data of 40 healthy subjects (17 young and 23 older people) w...
متن کاملFunctional Brain Imaging in Vision
The two-day Research Conferences preceding ARVO, sponsored by Vision Research, Elsevier and ARVO, are designed to provide updates on major areas of interest to the vision research community. The goal of the fourth conference, which took place on 28–29 April 2000, was to convene a multi-disciplinary audience interested in functional brain imaging in vision. The recent technological developments ...
متن کاملUsing functional magnetic resonance imaging (fMRI) to explore brain function: cortical representations of language critical areas
Pre-operative determination of the dominant hemisphere for speech and speech associated sensory and motor regions has been of great interest for the neurological surgeons. This dilemma has been of at most importance, but difficult to achieve, requiring either invasive (Wada test) or non-invasive methods (Brain Mapping). In the present study we have employed functional Magnetic Resonance Imaging...
