Interaction between glutamatergic and dopaminergic tone in the nucleus accumbens of mice: evidence for a dual glutamatergic function with respect to psychomotor control.
The rotation induced by a unilateral injection of the competitive NMDA receptor antagonist AP-5 was studied in mice with different tone in the central dopaminergic systems. AP-5 induced contralateral rotation in monoamine-depleted mice and in monoamine-depleted mice treated with a dopamine D-1 receptor agonist. In contrast, AP-5 induced predominantly ipsilateral rotation in monoamine-depleted mice treated with a mixed D-1/D-2 or a D-2 selective dopamine agonist and in mice with intact monoaminergic systems.
