Fig. 2.

Repeatability of stimulated efflux of adenosine from hippocampal brain slices. This figure illustrates the increased efflux of endogenous adenosine induced by two successive 6°C increases in slice temperature. Efflux was measured from groups of five slices that were incubated simultaneously in the same slice chamber (three replications). The magnitude of the increase in adenosine induced by the second temperature step was not different from the increase induced by the first stimulus (*P < 0.05).
