Changing the Connection Between the Hemispheres Affects Speech Perception
Summary: Using HD-TACS brain stimulation, researchers influenced the integration of speech sounds by changing the balancing processes between the two brain hemispheres.

When we listen to speech sounds, the information that enters our left and right ear is not exactly the same. This may be because acoustic information reaches one ear before the other, or because the sound is perceived as louder by one of the ears. Information about speech sounds also reaches different parts of our brain, and the two hemispheres are specialised in processing different types of acoustic information. But how does the brain integrate auditory information from different areas?
