Effect of the GABAA receptor antagonist picrotoxinin on the poststimulus inhibition of a DR 5-HT neuron in response to mPFC stimulation. A, PSTH of a DR 5-HT neuron inhibited by mPFC stimulation (arrow) (suppression of 260 msec to 24% of prestimulus firing rate).B, Picrotoxinin (1 mg/kg, i.v.) partially blocked the mPFC-induced inhibition. C, An additional intravenous picrotoxinin dose of 1 mg/kg further reduced the mPFC-induced inhibition (to 140 msec, 57% prestimulus firing rate). Bin size: 10 msec, 250 sweeps.
