Activation of serotonin (5-HT) receptors alone had no effect on PC circuitry. Representative images in (A) were taken before and after application of DOI, a 5-HT2A/2CR agonist. In (B–D) we show that DOI was without effect in each region followed over the entire range of stimulation frequencies used to activate the circuit.
