We have previously found that stimulation of serotonin 5-HT(1A) receptors inhibits the induction of long-term potentiation (LTP) in the rat visual cortex. In the present study, the selective 5-HT(1A) receptor agonist 8-hydroxy-2-(N,N-dipropylamino)tetralin (8-OH-DPAT) significantly reduced N- methyl-D-aspartate (NMDA) receptor-mediated synaptic responses recorded in Mg2+-free medium in rat visual cortical slices. In addition, there was good correlation between the inhibitory effects of 8-OH-DPAT on NMDA responses and LTP. These results suggest that 5-HT(1A) receptor stimulation inhibits the induction of LTP by suppressing NMDA receptor-mediated synaptic excitation in the rat visual cortex.
