Retrieval of a Behavioral Program in Fish Brain

Experimental observation of long-term memory formation and retrieval in vertebrate brain has long been an elusive goal. Here, Aoki et al. subject zebrafish to a reinforcement learning task and study neuronal activity as it emerges in a specific brain area of the dorsal pallium the following day. The findings highlight advantages of the zebrafish system to study adaptive behavior. For more information, see Aoki et al.,
