The neuromodulator, acetylcholine, may even help the main auditory brain circuitry distinguish speech from noise. While the phenomenon of these modulators influence has been studied at the level of the neocortex, where the brain s most complex computations occur, it has rarely been studied at the more fundamental levels of the brain, says R.
