title: Regulatory impairments following selective 6-OHDA lesions of the neostriatum.
abstract: 6-Hydroxydopamine lesions of the ventrolateral (VLC) but not anteromedial (AMC) caudate-putamen in rats resulted in a greater post-operative reduction in body weight and water intake than seen in animals with sham lesions. Once animals had fully resumed spontaneous food and water intake, a series of regulatory challenges were administered, and the AMC rats showed a reduced enhancement of drinking following injection of hypertonic saline. The results are interpreted in terms of a heterogeneous striatal convergence of nigrostriatal and cortical regulatory mechanisms.
