Inception of memories that guide vocal learning in the songbird

Abstract

An imitation circuit Animals, including humans, rely heavily on imitation and social learning, yet we know little about how this process operates in the brain. Zhao et al. used optogenetic manipulation of a synaptic pathway connecting auditory and vocal motor circuits to implant song memories sufficient to guide song learning into young zebra finches (see the Perspective by Clayton). Activation of this circuit overrode learning from live tutors. These experiments define circuits essential for social learning of songs from tutors and show that such memories can be localized.
