Following subtotal brain damage, localization of the corticofugal projection in the corona radiata and internal capsule can assist in evaluating a patient's residual motor capacity and predicting their potential for functional restitution. Data suggests that the corona radiata and superior capsular lesions may correlate with more favorable ...
basilar part of pons, anterior limb or genu of internal capsule, corona radiata, basal ganglia, thalamus, cerebral peduncle The main symptoms are dysarthria and clumsiness (i.e., weakness) of the hand, which often are most prominent when the patient is writing; but dysarthria or involuntary movement can also be seen in legs.

The external capsule is a series of white matter fiber tracts in the brain. These fibers run between the most lateral (toward the side of the head) segment of the lentiform nucleus (more specifically the putamen) and the claustrum. The white matter of the external capsule contains fibers known as corticocortical association fibers.
Middle cerebral artery syndrome is a condition whereby the blood supply from the middle cerebral artery (MCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the lateral aspects of frontal, temporal and parietal lobes, the corona radiata, globus pallidus, caudate and putamen.
A functional magnetic resonance imaging (fMRI) scan looks at oxygenated blood levels in the brain as a way of observing the activity of specific cortical areas. fMRI scans show dampened activity when anesthetized versus awake in rats, specifically claustrum connections to the medial prefrontal cortex (mPFC) and the mediodorsal thalamus (MD ...
The genu is the bend, or flexure in the V of the internal capsule. It is formed by fibers from the corticobulbar tract.The fibers in this region are named the geniculate fibers that carry upper motor neurons from the motor cortex to cranial nerve nuclei that mainly govern muscle motion of the head and face.
Neuroimaging pictures can show a number of different shapes, depending on the angle and location of the cut. Shape of human hippocampus and associated structures. Topologically, the surface of a cerebral hemisphere can be regarded as a sphere with an indentation where it attaches to the midbrain.
Positioned at the base of the forebrain and the top of the midbrain, they have strong connections with the cerebral cortex, thalamus, brainstem and other brain areas. The basal ganglia are associated with a variety of functions, including regulating voluntary motor movements , procedural learning , habit formation , conditional learning , [ 1 ...
