1 Application of either 5-HT or 8-OH DPAT, a mixed 5-HT(1A)/5-HT(7) receptor agonist, inhibited AMPA receptor-mediated excitatory post synaptic currents (EPSCs); this effect was mimicked by the 5-HT(1A) receptor agonist 8-OH PIPAT and blocked by the 5-HT(1A) antagonist NAN-190. 8-Hydroxy-2-(di-n-propylamino)tetralin 5-hydroxytryptamine (serotonin) receptor 1A Mus musculus

4 8-OH DPAT also modulated the current evoked by exogenously applied AMPA, inducing either a reduction or an increase of amplitude in distinct neurons; these effects were respectively blocked by 5-HT(1A) and 5-HT(7) receptor antagonists, indicating that both receptors exert a postsynaptic action. 8-Hydroxy-2-(di-n-propylamino)tetralin 5-hydroxytryptamine (serotonin) receptor 1A Mus musculus
