Left Caudate Nucleus (Nucleus caudatus sinister)
Educational content only — not medical advice.
Anatomy
The left caudate nucleus is an elongated, C-shaped subcortical mass of gray matter situated deep in the cerebral hemisphere, forming the lateral wall and floor of the left lateral ventricle. Composed of an anterior head (caput), arched body (corpus), and slender tail (cauda) that terminates near the amygdala, it forms the dorsal striatum alongside the putamen, regulating motor planning, goal-directed behavior, and associative learning.
Clinical notes
Bilateral atrophy and loss of GABAergic medium spiny neurons in the caudate nucleus is the hallmark neuropathology of Huntington disease, manifesting with choreiform involuntary movements, executive dysfunction, and psychiatric symptoms.
