This basal nucleus is named for its long, narrow, arched tail. It participates in voluntary movement circuits that are active during movement planning

Refers to nuclei located deep within white matter of the telencephalon, as opposed to surface gray matter (cerebral cortex).

The band of commissural fibers that connects neocortex of right and left cerebral hemispheres, effectively making one integrated brain out of the two hemispheres.

A midbrain bundle of corticospinal fibers coming from internal capsule and going through the ventral pons to the pyramid of the medulla oblongata. The bundle also contains corticobulbar fibers to substantia nigra, pontine nuclei, reticular formation, olivary nucleus, and cranial nerve nuclei

A white matter bundle composed of axons that come from the hippocampus and go to the septum or rostral thalamus or mamillary bodies

Significant component of the limbic system. The nuclei are involved in working memory (their damage results in "diencephalic amnesia"). It receives input from the hippocampus and amygdala via the fornix.

Located medial to the lateral ventricle, It is the oldest cerebral cortex. It is a component of the limbic system and it is essential for forming new memories, including spatial memory (how you got to your current location and how to return).

It is located within the rhinencephalon and associated with conscious olfaction. It receives olfactory input from the olfactory bulb via the lateral olfactory stria.

At the junction of the brain and spinal cord, most of the corticospinal fibers in the pyramidal tract cross to the contralateral side (decussate) and then descend in the dorsal half of the lateral funiculus as the lateral corticospinal tract.
