Localization of the motor hand area to a knob on the precentral gyrus. A new landmark.
Using functional magnetic resonance imaging (fMRI) we have evaluated the anatomical location of the motor hand area. The segment of the precentral gyrus that most often contained motor hand function was a knob-like structure, that is shaped like an omega or epsilon in the axial plane and like a hook in the sagittal plane. On the cortical surface of cadaver specimens this precentral knob corresp...
متن کاملAphemia after infarction of the left precentral gyrus and premotor area.
The term “aphemia” is now used to describe a motor disorder that affects speech production but leaves the comprehension of spoken and written language intact. Aphemia is a specific form of mutism. Aphemia was formerly referred to as phonetic disintegration, pure anarthria, apraxic dysarthria, cortical dysarthria, verbal apraxia, subcortical motor aphasia, pure motor aphasia, small or mini Broca...
متن کاملThe activity in the contralateral primary motor cortex, dorsal premotor and supplementary motor area is modulated by performance gains
There is growing experimental evidence that the engagement of different brain areas in a given motor task may change with practice, although the specific brain activity patterns underlying different stages of learning, as defined by kinematic or dynamic performance indices, are not well understood. Here we studied the change in activation in motor areas during practice on sequences of handwriti...
متن کاملArterial vascularization of primary motor cortex (precentral gyrus).
BACKGROUND The precentral gyrus (PG) is the primary motor area and is one of the most eloquent brain regions of neurosurgical interest. Although the arterial supply to the PG is generally known, contributions from different arterial branches such as the anterior cerebral artery (ACA), posterior cerebral artery (PCA), and middle cerebral artery (MCA) have not been comprehensively studied. The ai...
متن کاملProjections of the claustrum to the primary motor, premotor, and prefrontal cortices in the macaque monkey.
The claustrum is interconnected with the frontal lobe, including the motor cortex, prefrontal cortex, and cingulate cortex. The goal of the present study was to assess whether the claustral projections to distinct areas within the frontal cortex arise from separate regions within the claustrum. Multiple injections of tracers were performed in 15 macaque monkeys, aimed toward primary motor area ...
