The neurochemical anatomy of the human nucleus accumbens was studied by comparing the distributional patterns of [3H]DAMGE (mu opioid receptor), [3H]bremazocine (kappa opioid receptor), [3H]SCH-23390 (D1-like dopamine receptor), [3H]7-OH-DPAT (D3 dopamine receptor) binding, preproenkephalin mRNA and acetylcholinesterase activity in sections of post mortem human striatum. Our results demonstrate the presence of at least two neurochemically distinct divisions within the human nucleus accumbens, which may be homologous to the 'shell' and 'core' divisions of the nucleus as found in the rat.
