nucleus accumbens
A region in the basal forebrain involved in reward, pleasure, and addiction. Used in neuroscience and medical contexts.
The nucleus accumbens plays an important role in the reward system.
Standard kanji form for this anatomical term.
Variant kanji form using 座 instead of 坐; both are used in medical literature.
From 側 (side) + 坐/座 (seat) + 核 (nucleus), a calque of the English term 'nucleus accumbens' (literally 'leaning-against nucleus').
