The parameters of the open field test, including latency period,total number of ambulations, rearing and grooming, remainedunaffected either by aluminum treatment or GBE treatment or both,during the test period, and the group means were quite similar. Nosignificant effects of aluminum on general activity of treated ratswere found. This agrees with the results of previous studies show-ing no differences on general activity between aluminum-treatedand non-aluminum-treated rats
