Left Putamen (Putamen sinister)
Educational content only — not medical advice.
Anatomy
The left putamen is a large, rounded subcortical nucleus situated lateral to the globus pallidus and internal capsule in the left cerebral hemisphere. Together with the globus pallidus, it constitutes the lentiform nucleus, and together with the caudate, it forms the striatum. Receiving rich dopaminergic input from the substantia nigra, it coordinates movement preparation, execution, and habit formation.
Clinical notes
The putamen is the most common site of spontaneous hypertensive intracerebral hemorrhage (due to rupture of the lenticulostriate Charcot arteries), classically producing dense contralateral hemiplegia and hemianesthesia.
