Correlation between number of type 2 serotonin receptors in the frontal cortex and intensity of serotonin-induced head jerks in mice
This paper shows interlinear differences discovered in the number of S2 receptors in the cerebral cortex and they are compared with the intensity of 5-HT-induced head jerking in mice of inbred lines. The number of S2 receptors was estimated from the quantity of tritium-spiperone, which is specifically bound by brain membrane preparations. Specific binding was assessed as the difference between the quantity of label bound in the absence and in the presence of methylsergide, a drug which specificably blocks S2 receptors. The presence of high correlation be= tween the number of S2 receptors and the number of head jerkings in mice reflects a genetic connection between this form of behavior and the serotonin system, and it in no way signifies that this phenomenon is controlled purely by the serotonin system and cannot be modulated by other mediator systems, for example, the adrenergic system.
