TL;DR

Peripheral electrical stimulation of the rat produced a "dose-dependent" analgesia both in intact and in spinal animals, and Naloxone, a narcotic antagonist, almost completely reversed this analgesia.

Abstract

Peripheral electrical stimulation of the rat produced a "dose-dependent" analgesia both in intact and in spinal animals. Naloxone, a narcotic antagonist, almost completely reversed this analgesia. It is felt that peripheral electroanalgesia acts via the release of endogenous narcotic-like substances, the enkephalins, at spinal and supraspinal centres.
