Oxygen deprivation-induced death of CGN. Neurons were incubated at different oxygen concentrations (1% O2, whitebars; 5% O2, black bars) for the indicated intervals. Viability was determined 24 hr after transfer to normoxic conditions. Data are expressed as mean ± SEM percentages of viability (n = 3; *p < 0.05; **p < 0.01; ANOVA, followed by Tukey'spost hoc test compared with normoxic controls).
