Researchers have traced how the brain filters out background noise during speech using signals between the motor and auditory cortices. These milliseconds-long electrical signals, called auditory corollary discharge, originate in the motor cortex's precentral gyrus and travel to the auditory cortex's superior temporal gyrus.
