Abstract
The concept that "denervation" or "pharmacological disuse" supersensitivity develops in central neuronal systems subsequent to sustained attenuation of normal neurohumoral mechanisms is reviewed. Particular emphasis is placed on biochemical and electrophysiological parameters of supersensitivity in dopaminergic (striatal) neuronal systems. The possible applicability of theories invoking changes in receptor sensitivity to the phenomenon of narcotic tolerance and physical dependence and to psychoactive drug therapy is discussed.
