Postdocs Tom Harmon (Mooney Lab) and Seth Madlon-Kay (Pearson Lab), and faculty John Pearson and Rich Mooney, have a new article out in Cell Reports. Vocal communication in mice and mammals more generally, depends on distinguishing self-generated vocalizations from other sounds. Vocal motor corollary discharge (CD) signals are thought to support this ability by adaptively suppressing auditory cortical responses to auditory feedback. Their article, "Vocalization modulates the mouse auditory cortex even in the absence of hearing," details their surprising finding that vocal production suppresses the auditory cortex of both hearing AND deaf mice.
