Figure 6. Spreading neuroprotection from an excitotoxic insult.

Neuroprotection against a subsequent direct excitotoxic challenge is also spread by an excitotoxic insult (n = 3). Basal cell death is indicated by the dotted line (UT). Data are expressed as mean ± S.E.M (one way ANOVA with post hoc Tukey’s test. ‘ns’ denotes p > 0.05, **denotes p < 0.01, relative to control). Experiments were performed using independent neuronal preparations.
