Auditory Imaging Unit

When sound reaches the ear, it is transduced to electrical signals, which are extensively processed by hearing centers of the brain. This processing determines what we hear. The Auditory Imaging Unit studies how the human brain processes sound using imaging techniques such as functional magnetic resonance imaging (fMRI) and magnetoencephalography (MEG).

sound evoked activationOur past and present work includes investigations into the neural representations of perceived loudness, pitch, repetition rate, and the segregation of our auditory environment into distinct objects or “streams.” The Unit is part of the Eaton-Peabody Laboratories and has close ties to the Athinoula A. Martinos Center.
