Cholinergic depletion in nucleus accumbens impairs mesocortical dopamine activation and cognitive function in rats.

Laplante F, Zhang ZW, Huppe-Gourgues F, Dufresne MM, Vaucher E, Sullivan RM (2012) Cholinergic depletion in nucleus accumbens impairs mesocortical dopamine activation and cognitive function in rats. Neuropharmacology 63(6):1075-1084. doi: 10.1016/j.neuropharm.2012.07.033

Summary: Current thought is that loss of cholinergic function in the nucleus accumbens (N.Acc) is associated with schizophrenia. This deficit is accompanied by low dopaminergic activity in the prefrontal area, which adversely affects working memory. Rats received bilateral injections totaling 500 ng of anti-ChAT-SAP (Cat. #IT-42) into the N.Acc; rabbit IgG-SAP (Cat. #IT-35) was used as a control. Lesioned animals had markedly reduced mesocortical dopamine activation, which corresponded with cognitive impairments. The data suggest that loss of cholinergic neurons in the N.Acc causes loss of dopamine function in the mesocorticolimbic system.
