Hearing and Donuts (Brain and Bagels) Seminar

May 3 @ 8:30 am - 9:30 am

Presenter: Carrie Niziolek, Ph.D., Assistant Professor of Communication Sciences and Disorders, Waisman Center Investigator
Topic: The Sensory Consequences of Speaking: Auditory Cortical Suppression During Self-produced Sounds

Activity in auditory cortical regions is continuously modulated by the predictability of the environment. Motor acts such as speaking are one kind of predictable event, and modulate neural responses accordingly: the activity recorded from auditory cortex during self-vocalization is systematically different from that recorded in the presence of external vocalizations. This modulation, typically described as a suppression, has several sources at multiple levels of the auditory pathway which vary in their mechanism and level of specificity. This talk will attempt to reconcile different descriptions of auditory cortical suppression by delineating the contributions of peripheral and central mechanisms as measured by varied techniques across animal and human studies.
