Calcium-dependent increase in efflux of [1-3H] taurine from the superfused rat cerebellar cortex in vivo

Abstract
High (40 mM) potassium stimulation has been shown to increase the effluxin vivo of [1-3H] taurine from the superfused rat cerebellar cortex by 46%, P3H] taurine in the cerebellar cortex is not yet known, but this region of the brain contains exceptionally high levels of endogenous taurine. The calcium dependency of the release of labelled taurine raises the possibility that taurine has some neuron-humoral role in the cerebellar cortex.
