Fig. 4. Concentration-response curves for water maze performance (mean of 4 days of the distance traveled to find the platform in centimeters) (♦), and the caspase-3 activation positive profile per mm2in the pyramidal cell layer of the cornu ammonis 1 area of the hippocampus (▪). n = 8 mice for water maze task and n = 5 mice for caspase-3 activation. Data expressed as mean ± SD. C3A = caspase-3 activation.
