Figure 3. Relative intracellular calcium change in response to hypoxia plus glutamate (3 mM). The brain slices were either treated with dexmedetomidine (100 nM) or without (control). Traces show averaged data from all slices in treatment group. Vertical bars show mean plus/minus SD 14 min after application of hypoxia plus glutamate. The arrow indicates the time of hypoxia plus glutamate application. n = number of slices studied.
