The findings, reported August 18 in the journal Cell, suggest that auditory and speech processing occur in parallel, contradicting a long-held theory that the brain processed acoustic information then transformed it into linguistic information.

If speech processing follows a serial pathway as the traditional model suggests, the stimuli would likely distort the patients' perception of speech. On the contrary, while participants experienced auditory noise hallucinations induced by the stimuli, they were still able to clearly hear and repeat words said to them. However, when the STG was stimulated, the participants reported that they could hear people speaking, "but can't make out the words."
