The 5-HT3 receptor antagonist, RS-56812, enhances delayed matching performance in monkeys.


Substantial evidence indicates that serotonin receptors are involved in the regulation of acetylcholine release in CNS regions important to mnemonic processes, and may thus be exploited pharmacologically as targets for memory improvement. In the present study, the (R) and (S) isomers of a potent serotonin (5-HT3) receptor ligand, RS-56812 were evaluated for… (More)
