- What it is
- The outer, lens-shaped part of the lentiform nucleus, lying lateral to the globus pallidus and internal capsule and deep to the insula; strands of grey matter link it to the caudate across the capsule (the "striatum").
- Function
- Receives motor and sensory cortex input and, with the caudate, shapes the scaling and smoothness of learned movements.
- Size
- About 3 cm long, 2 cm high and 1 cm wide
- Clinical note
- The lenticulostriate arteries supplying it are the commonest site of hypertensive brain haemorrhage.
