The sensitivity of hippocampal pyramidal neurons to serotonin in vitro: effect of prolonged treatment with clorgyline or clomipramine.
The sensitivity of hippocampal pyramidal neurons to the depressant action of serotonin was studied in hippocampal slices obtained from rats treated repetitively with clomipramine (10 mg/kg i.p.; 10 days or 4 weeks), with clorgyline 0.3 mg/kg s.c.; 10 days) or with the vehicle. Whereas clorgyline produced a very pronounced subsensitivity to serotonin, a moderate, non-significant reduction in sensitivity was observed with clomipramine. These electrophysiological findings are consistent with previous biochemical studies.
