Research Abstract

Imprinting behavior is a good model for studying juvenile learning, because a critical period for learning is present, it can be established by an easy training and it occurs also in chicks. In this study, we have elucidated a neural circuit responsible for this behavior, and found that the activity of this circuit and performance of imprinting behavior was positively correlated. Moreover, the neural activity of this circuit depended on the NR2B-containing NMDA receptors, which dominate during the juvenile period.
