Functional magnetic resonance imaging (fMRI), a class of techniques that images intrinsic
blood signal change with magnetic resonance (MR) imagers, has in the past 3 years …

Humans and non-human primates have several motor areas. Exactly how many is a matter
of current debate. A proper parcellation of motor areas must be based on correlated …

Neural plasticity--the brain's ability to change in response to normal developmental
processes, experience, and injury--is a critically important phenomenon for both …

Background and Purpose—The effect of ebselen, a seleno-organic compound with
antioxidant activity through a glutathione peroxidase–like action, on the outcome of acute …

Functional magnetic resonance imaging (FMRI) is a new, noninvasive imaging tool thought
to measure changes related to regional cerebral blood flow (rCBF). Previous FMRI studies …

Image‐to‐image fluctuation due to physiological motion is a major limitation to the accurate
detection of neuronal activity with functional MRI. In this paper, a new and general technique …

Background Spreading depression of Leao has been hypothesized as the basis for the
visual aura of the migraine attack, supported by cerebral blood flow measurements of …

Neurophysiological research suggests that understanding the actions of others harnesses
neural circuits that would be used to produce those actions directly. We used fMRI to …

Background and Purpose—Studies of cerebral activation of motor function after ischemic
stroke may enhance our understanding of the underlying mechanisms of motor functional …

We show that the EPI time course in functional MR imaging at 4 Tesla displays a multiphasic
response in response to photic stimulation. Focal areas of gray matter display an initial …
