Distance traveled during the cocaine challenge in the open field. An acute injection of cocaine significantly increased the distance traveled in all groups as expected. Rats exposed to MA during preadolescence traveled significantly greater distances during the first 30 min following the cocaine challenge compared to the control group. The increased locomotion during the first 30 min following the cocaine challenge (COC30) was greater in MA exposed males compared to male controls (* p<0.05).
