Abstract
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 to repress long-term potentiation.
