Hippocampal Dysfunction Provoked by Mercury Chloride Exposure: Evaluation of Cognitive Impairment, Oxidative Stress, Tissue Injury and Nature of Cell Death

Figure 3

The effects of HgCl₂ exposure (0.375 mg/kg/day) for 45 days on the short- and long-term memory of male Wistar rats evaluated in step-down inhibitory avoidance. The results are expressed as the mean ± SEM of the (a) latency to step down in seconds (1.5 h) and (b) latency to step down in seconds (24 h). compared to the control group (Student’s t-test).
