In a coronal section through the middle of the lentiform nucleus, two medullary laminae are seen dividing it into three parts. The lateral and largest part is of a reddish color, and is known as the putamen, while the medial and intermediate are of a yellowish tint, and together constitute the globus pallidus; all three are marked by fine radiating white fibers, which are most distinct in the ...
The putamen (/ p j u ˈ t eɪ m ə n /; from Latin, meaning "nutshell") is a subcortical nucleus with a rounded structure, in the basal ganglia nuclear group. It is located at the base of the forebrain and above the midbrain. The putamen and caudate nucleus together form the dorsal striatum.
posterior limb of the internal capsule, basilar part of pons, and corona radiata, red nucleus, lentiform nucleus, superior cerebellar artery infarcts, anterior cerebral artery infarcts It displays a combination of cerebellar and motor symptoms, including weakness and clumsiness, on the ipsilateral side of the body.

The anterior limb of the internal capsule (or crus anterius) is situated in front of the genu, between the head of the caudate nucleus and the lentiform nucleus. [4] It contains: Thalamocortical fibers passing from the lateral thalamic nuclei to the frontal lobe [4] Corticothalamic fibres passing from the frontal lobe to the lateral thalamic ...
The medial longitudinal fasciculus (MLF) is a prominent bundle of nerve fibres which pass within the ventral/anterior portion of periaqueductal gray of the mesencephalon (midbrain). [1] It contains the interstitial nucleus of Cajal , responsible for oculomotor control, head posture, and vertical eye movement.
The striatum includes the caudate nucleus (top), and the lentiform nucleus (the putamen (right) and the globus pallidus (lower left)) The striatum is the largest structure of the basal ganglia. The striatum is divided into two subdivisions, a ventral striatum and a dorsal striatum, based upon function and connections.
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. These fibers are responsible for connecting the cerebral cortex to another cortical area ...
The internal arcuate fibers are composed of axons of the gracile nucleus and the cuneate nucleus. The cell bodies of the nuclei lie contralaterally. The medial lemniscus is part of the somatosensory dorsal column–medial lemniscus pathway, which ascends in the spinal cord to the thalamus. [1]
