Summary
Mice and rats were trained to avoid shock in a modified shuttle box. Following training the animals were treated with reserpine. The suppression of the conditioned avoidance response induced by reserpine was partially and temporarily reversed by an injection of l-3,4-dihydroxyphenylalanine, and the suppression of locomotor activity was completely antagonized for approximately the same duration.
