Each side of the brain is functionally associated with the ipsilateral half of the body.
The cerebral cortex is responsible for subconscious functions like breathing and heart control.
The outermost section of the cerebral hemispheres is gray matter built of six cellular layers.
The brain "floats" in a protective layer of cerebrospinal fluid.
The cellular organization of the cortex cerebri is the same in all regions.
Internal capsule is made of projection fibers.
Basal ganglia are concerned with motor control.
Projection fibers in the brain connect the right and left hemispheres.
Primary visual field is located around sulcus calcarinus

Which of the following connections are classified as projection fibers?
Superior occipitofrontal fasciculus

Tremor at rest
Huntingdon's disease is characterized by neuronal degeneration in which of the following structures?
Globus pallidus, Internal segment
Globus pallidus, External segment
A pathway that extends along the medial border of the caudate nucleus and reciprocally connects the amygdala and the hypothalamus is the
Stria medullaris thalami
Medial forebrain bundle
Bilateral cortical damage to the inferomedial temporal cortex may result in
