1. Administration of MK-801 a selective antagonist of the NMDA receptors (50, 100 and 150 micrograms/kg, s.c.) elicited in adult cats ataxia and loss of equilibrium. A dose-response effect was observed. 2. Administration of DNQX, a selective antagonist of the non-NMDA receptors, even with doses 20 times higher than those employed with MK-801, did not produce any behavioural disturbances. 3. Previous injection of SCH 23390, a selective parenteral antagonist of dopamine D1 receptor, reduced significantly the intense ataxic effects of MK-801, while sulpiride only increased the latency of the symptoms. 4. The results are discussed considering the reported interactions between the dopaminergic and glutamatergic systems.
