Study sheds new light on how the brain distinguishes speech from noise

For the first time, researchers have provided physiological evidence that a pervasive neuromodulation system—a group of neurons that regulate the functioning of more specialized neurons—strongly influences sound processing in an important auditory region of the brain. The neuromodulator, acetylcholine, may even help the main auditory brain circuitry distinguish speech from noise. “While the phenomenon of […]
