  • In the present experiments we have attempted to determine whether one or more of the biogenic amines are involved in the prehatching and hatching behavior of the chick. Injection of reserpine first induces a depression in ongoing spontaneous motility on day 16 of incubation. Prior to this, reserpine has no apparent effect on embryonic behavior. Reserpine injections on days 17-19 induce a similar behavioral depression that lasts for at least six hours; by 24 hours post-injection the behavior of… CONTINUE READING
