BACKGROUND AND PURPOSE In Moyamoya disease, the relationship between cerebral hemodynamics and angiographic findings has not been fully evaluated. The purpose of this study is to evaluate hemodynamics in Moyamoya disease with perfusion-weighted MR imaging (PWI) and cerebral angiography. METHODS Twenty patients with Moyamoya disease were the subjects. Mean transit time (MTT) derived from PWI w...

Abstract The frontal lobes represent a large area, consuming approximately one-third of the cortical surface of the brain. This area is involved directly and indirectly across a wide spectrum of human thought, behavior and emotions. The irony of the frontal lobes may best be described as the area of the brain we know the most about but understand the least. For example, frontal lobe functioning...

This special issue of the Schizophrenia Bulletin focuses on three brain areas hypothesized to play a role in the etiology of schizophrenia--the frontal lobes, the basal ganglia, and the temporal lobes. Contributors to the issue review evidence from brain-imaging, post-mortem, and psychopharmacological studies that support the involvement of each of these important brain areas in schizophrenia. ...

BACKGROUND Imaging and postmortem studies provide converging evidence that, beginning in adolescence, gray matter volume declines linearly until old age, while cerebrospinal fluid volumes are stable in adulthood (age 20-50 years). Given the fixed volume of the cranium in adulthood, it is surprising that most studies observe no white matter volume expansion after approximately age 20 years. We e...

The purpose of this research is to examine and assess the relation between a pilot’s concentration reaction time with specific brain activity during short-haul flights. Participants took part in one-hour long flight sessions performed on FNPT II class simulator. Subjects were instructed respond unexpected events that occurred flight. brainwaves each participant recorded Emotiv EPOC+ Scientific ...
