Concentrations of taurine have been measured in 44 microdissected rat brain nuclei or areas. Taurine is ubiquitously present and distributed unevenly in the rat brain: the ratio of the highest (pyriform cortex) to lowest (midbrain reticular formation) concentrations is 4.7:1. High taurine levels were found in cerebral cortical areas, caudate-putamen, cerebellum, median eminence, and supraoptic nucleus. Acute pain stress reduced taurine levels in the hypothalamus and the lower brainstem nuclei but not in cortical areas. Increased locomotor and behavioral activities following a high dose of amphetamine elevated taurine concentrations significantly in the substantia nigra and locus ceruleus.

Taurine is an inhibitory amino acid in the CNS. When supplied to rats it produces analgesia in some acute pain tests. Here we examined the effect of taurine supplementation on sensitivity to pain in intact rats, and whether perioperative dietary supplementation with taurine in rats would suppress autotomy, a behavior produced by peripheral neurectomy and related to neuropathic pain. Thermal pain sensitivity of intact rats consuming 1% taurine in the drinking solution for 2 weeks was not significantly different from that of control rats. Autotomy levels, determined in rats consuming taurine pre-, post- or perioperatively were significantly lower than in matching control groups. We conclude that taurine plays an important role in the autotomy model, presumably by protecting inhibitory neurons in the CNS against an excitotoxic damage triggered by injury discharge and ectopic input from the severed nerves.
