Timeline of events for locomotion experiments. Being placed, on day 1, in the locomotion chamber for 25 minutes habituated all animals to the testing apparatus (blank box). The next day, animals received either saline or cocaine. Five days later, subjects were allowed to explore the chamber once again to insure prior drug exposure had no lasting effects and then received the opposite compound the following day. (Hab., habituation).
