Behavioral Consequences of 5-HT1B Receptor Gene Deletion
Serotonin (5-hydroxytryptamine, 5-HT) is a biogenic amine which is involved in a wide range of physiological functions including sleep, appetite, pain perception, sexual activity, memory and mood control (for a review see Wilkinson et al. 1991). A central serotonin deficit has been associated with behaviors such as suicidality, impulsive violence (Higley et al. 1992), depression and alcoholism (Eichelmann et al. 1992), and serotoninergic drugs are used in the treatment of a number of pathological states including migraine, depression and anxiety (Sleight et al. 1991). The multiple actions of serotonin are mediated by the interaction of this amine with at least 14 receptors (for a review see Saudou and Hen 1994), most of which belong to the G-proteincoupled receptor family.
