The long-term effects of dopamine (DA)-depleting brain lesions on behavior and spontaneous activity of Type II striatal neurons were measured in rats after intraventricular injection of the neurotoxin 6-hydroxydopamine (6-OHDA). Spontaneous firing rates were increased relative to control values when recorded 4-8 days or 4-6 weeks postlesion in animals displaying aphagia, adipsia and akinesia. In contrast, spontaneous activity was not increased when recorded 4-6 weeks after the lesion in animals that had recovered from behavioral deficits. Other animals that had recovered from the effects of an earlier 6-OHDA treatment were given either a second injection of 6-OHDA or a systemic injection of haloperidol, a DA receptor antagonist. In both groups, discharge rates were elevated relative to control levels in association with a reinstatement of behavioral deficits. These results demonstrate that behavioral recovery after large DA-depleting brain lesions is associated with a return of spontaneous activity of striatal neurons to normal levels, and suggest that both behavioral and electrophysiological measures are dependent on the functioning of residual elements of the DA system.
