Taurine is present in relatively high (mM) concentrations in mammalian tissues, including the brain. Despite extensive studies of its synthesis, release in response to nerve stimulation and possible neuronal or extraneuronal uptake there is still no consensus about its functions (9,8,12). It has variously been designated as a neurotransmitter, neuromodulator, a modulator of calcium fluxes, and

Thus, for example, the “neuroprotective” effects of taurine may be related to the osmoregulatory, antioxidant and calcium ion modulating functions of taurine.
