Central 5-HT4 Receptors: Electrophysiology
Serotonin receptors of the 5-HT4 subtypes are expressed at relatively high densities in several regions of the mammalian central nervous system. As such, these receptors are likely to participate in at least some of the functions served by serotonin in the brain. The challenge is to identify, at a behavioral level, those processes involving 5-HT4 receptors and to elucidate, at cellular and molecular levels, how these processes are made possible by 5-HT4 receptor activation. In this regard, the electrophysiological effects mediated by 5-HT4 receptors constitute an important middle ground. 5-HT4 receptors regulate the electrophysiological properties of individual neurons; thus in turn, the functioning of neuronal networks. It is ultimately the effect of 5-HT4 receptors on the functioning of these networks that impact behavioral and thought processes.
