beta-Endorphin-induced psychomotor excitation in the cat.

The effect on behavior of synthetic human beta-Endorphin injected into the cerebral ventricles of the cat was investigated in these experiments. beta-endorphin produced psychomotor excitation (i.e., restlessness, apprehension, flight and locomotion), accompanied by pupillary dilatation and tremor. Between periods of locomotion, the cat sat moving its head… CONTINUE READING
