“Hanson has shown that amphetamines increase the concentration of catecholamines in the synaptic cleft by stimulating their release from the interneuronal storage vesicles.”

“These abnormal responses are generally attributed to the removal of inhibitory signals that influence the interneuronal networks controlling the response.”

“Referred pain patterns, local twitch responses and autonomic phenomena are thought to be related to interneuronal integration in the spinal cord.”
