Scientists identify how repeated cocaine use increases addictiveness

Experimental designs of the induction (experiment 1) and expression (experiment 2) phase of cocaine-induced hyperlocomotion with a timeline. Groups were distributed according to the experiment.

During the sensitization period, the injections were applied on the odd days (1, 3, 5, 7, 9, 11, 13, and 15). The first injection was applied in the open-field and two hours later in the animalĀ“s home-cage. On the even days (2, 4, 6, 8, 10, 12, and 14), animals were not handled. Credit: Biomedicines (2023).
