the effect of endogenous serotonin on long-term potentiation (ltp) in region cai was studied by blocking 5-ht2 receptors with ketanserin in rat hippocampal slices. such a block significantly en-hanced long-term potentiation of the cai population spike induced by high frequency stimulation of the schaffer collateral/ commissural pathway. this implies that serotonin acts on 5-ht2 receptors in cai...
