Motor-related signals in the auditory system for listening and learning

Curr Opin Neurobiol. 2015 Aug;33:78-84. doi: 10.1016/j.conb.2015.03.004. Epub 2015 Mar 28.


In the auditory system, corollary discharge signals are theorized to facilitate normal hearing and the learning of acoustic behaviors, including speech and music. Despite clear evidence of corollary discharge signals in the auditory cortex and their presumed importance for hearing and auditory-guided motor learning, the circuitry and function of corollary discharge signals in the auditory cortex are not well described. In this review, we focus on recent developments in the mouse and songbird that provide insights into the circuitry that transmits corollary discharge signals to the auditory system and the function of these signals in the context of hearing and vocal learning.
