Behavioural Correlates of the Activation of 5-HT Receptors

  • Chapter
Serotonin

Abstract

The precise role of neurones containing 5-hydroxytryptamine (5-HT) in behavioural control is unclear. A contributing factor to our lack of understanding has undoubtedly been the use of pharmacological tools devoid of selectivity for the three major populations of 5-HT receptor, 5-HT1like, 5-HT2 and 5-HT3 (and their subtypes), thought to exist in the CNS. A number of novel drugs with appreciable degrees of affinity and selectivity for these sites have recently become available and are proving to be useful tools for the re-examination of the functional roles of 5-HT. In this review of the behavioural pharmacology of 5-HT, attention is concentrated on some of the behavioural responses (largely in rodents) that have been proposed to reflect activation of specific 5-HT receptor subtypes. Unfortunately, little is known about some of the more complex behavioural paradigms that may help to predict the therapeutic potential of selectively manipulating 5-HT receptor subtypes in man.
