Abstract

Listen to yourself: Vocalization feedback monitoring When we talk, we need to be able to both hear external stimuli, and keep track of our own voice. In several species, including humans, auditory neurons are suppressed during vocalization, but the function of this was unclear. New work suggests that the 'suppressed' neurons are actually enhanced in their sensitivity to self-generated sounds. Steven Eliades and Xiaoqin Wang found that in freely behaving marmosets, neurons in the primary auditory cortex are more sensitive to perturbations in vocal feedback despite the general suppression. This suggests a possible mechanism for active monitoring of subtle changes of your own voice. Deficits in such feedback monitoring have been suggested as a cause for human speech disorders such as stuttering.
