Flurazepam effects on rat cerebellar Purkinje cells.

1. Cerebellar Purkinje cell activity was recorded in urethane anaesthetized rats. 2. Flurazepam, infused intravenously in divided doses totalling 4 mg/kg, decreased simple spike activity, increased complex spike activity and prolonged local surface inhibition. 3. Iontophoretically applied flurazepam enhanced the effect of GABA and elicited a bursting pattern of discharge when released using larger currents for ejection.
