Come to URCAD on Wednesday, April 25, where INDS major Tziona NessAiver will present her research “Learning To Listen: The Sound of the Brain’s Alpha Waves” in the UC Ballroom at 1 p.m.

While electroencephalogram, (EEG) data is commonly used to investigate the brain through analytical graphs of electrical output, this study tests the possible use of EEG data when converted to sound; specifically to augment human communication. An EEG gathers electrical signals from the neural cortex via electrodes placed on the scalp. This study converted to sound the alpha wavelength signals collected from a subject’s visual cortex during two distinct brain-states: eyes-closed and eyes-opened.
