Abstract
Substance P (SP) and related tachykinins administered either intracerebroventricularly or directly into the ventral tegmental area of the mesencephalon of rat brain caused increased locomotor activity, grooming behaviour and wet dog shakes. Kassinin, eledoisin, neurokinin A and DiMe-C7, agonists with some selectivity for the SP-E-receptor elicited the greatest locomotor activity and wet dog shake responses, whereas SP and physalaemin which are more selective for the SP-P-receptor were most effective in eliciting the grooming response.
