Methionine enkephalin inhibits the bursting activity of the Br-type neuron inHelix pomatia L.

Abstract
The present study demonstrates that methionine enkephalin can inhibit the normal bursting activity pattern of the RPal or Br-type neuron and this inhibition can be blocked by prior treatment with naloxone, the selective opiate antagonist. The study demonstrates indirectly the presence of opiate-like receptors inHelix pomatia.
