The role of basal ganglia in reinforcement learning and imprinting in domestic chicks
EI Izawa, S Yanagihara, T Atsumi, T Matsushima - Neuroreport, 2001 - journals.lww.com
Abstract Effects of bilateral kainate lesions of telencephalic basal ganglia (lobus
parolfactorius, LPO) were examined in domestic chicks. In the imprinting paradigm, where
chicks learned to selectively approach a moving object without any explicitly associated
reward, both the pre-and post-training lesions were without effects. On the other hand, in the
water-reinforced pecking task, pre-training lesions of LPO severely impaired immediate
reinforcement as well as formation of the association memory. However, post-training LPO …
