Time course of basal (--) and K⁺-evoked (--) glutamate release from cerebellar slices in normoxia and basal (-∆-) and K⁺-stimulated (-▴-) glycine release in ischemia in 7-day-old (a) and 3-month-old (b) mice. Note the fourfold differences in the scale of the -axis in panels (a) and (b). The results are means of 4–8 independent experiments with SEMs indicated. Ischemia significantly () enhanced the release in both age groups, but K⁺ stimulation was effective only in ischemia in 7-day-old mice and in normoxia in 3-month-old mice.
