The 'cocktail party problem' - what goes on in our brains when we listen to someone's voice yet ignore many others - has puzzled researchers down the years. Using electrophysiological recordings from neurosurgery patients listening to two speakers simultaneously, Nima Mesgarani and Edward Chang determine the neural correlates associated with the internal representation of attended speech. They find that the neural responses in the auditory cortex represent the attended voice robustly, almost as if the second voice were not there.
