Effects HgCl₂ administration (0.375 mg/kg/day) for 45 days on the learning, short- and long-term memory of male Wistar rats evaluated in the elevated T maze (ETM) test. The results are expressed as the mean ± SEM of the: (A) number of re-expositions (learning function); (B) time in seconds in the enclosed arms for the first time test of long-term memory; and (C) time in seconds in the enclosed arms for the first time test of short-term memory. * p < 0.05 compared to control group (Student’s t-test).
