Brain responses found to originate from previously unknown source

(McGill University) Scientists at the Montreal Neurological Institute and Hospital at McGill University have made an important discovery about the human auditory system and how to study it, findings that could lead to better testing and diagnosis of hearing-related disorders.The researchers detected frequency-following responses (FFR) coming from a part of the brain not previously known to emit them. FFRs are neural signals generated in the brain when people hear sounds.
