Repeated cocaine reorganizes striatal ensembles along the ventral-dorsal axis

Michael Z. Leonard, Hannah B. Elam, Ainoa Konomi-Pilkati, Kathryn J. Bjornson, Maxime Chevée, Erin S. Calipari

This study shows that repeated cocaine exposure reorganizes striatal neural activity patterns along the ventral-dorsal axis in mice, leading to distinct changes in neuronal responses.
