Definition

The “putamen” (botanical term for the stony core of a fruit like the peach) is a nucleus located deep within the brain, forming a part of the basal ganglia.

Nomenclature

Striatum/neostriatum = caudate nucleus (nucleus caudatus) + putamen

Lentiform nucleus = putamen + globus pallidus

Corpus striatum (dorsal division) = caudate nucleus + putamen + globus pallidus

Current Knowledge

Anatomy

The putamen surrounds the globus pallidus superolaterally. Anatomically, along with the globus pallidus, it forms the lentiform nucleus. Functionally, along with the caudate nucleus, it belongs to the neostriatum. Thin bundles of axons called Wilson’s pencils course the putamen as if radiating from the globus pallidus, giving it a striated appearance. The putamen is nourished by lenticulostriate arteries (penetrating branches of anterior and middle cerebral arteries).

Relations

Lateral – external capsule, claustrum, extreme capsule, insular cortex.

Medial – a sheet of myelinated nerve fibers...
