title: On the possibility that opiate and ethanol actions are mediated by similar mechanisms.
abstract: Opiates and alcohol modify neuronal electrical activity in many sites of the nervous system. Both act as depressants or stimulants of cell firing depending upon the type of cell studied. Alcohol seems to act upon some nerves by changing their membrane ionic conductance, while opiates seem to affect synaptic events. However, all of the known neural actions of these substances involve calcium-dependent mechanisms. A hypothesis is proposed to account for these facts.
