Readers of 13.7 may have noticed headlines this past week trumpeting the latest "brain reading" breakthroughs coming out of UC Berkeley's neuroscience laboratories. I've written about related work before, here, here, and here. This latest research is dazzling. Direct measurement of neural activity in higher areas of auditory cortex allows scientists to determine what continuous speech sounds (words, sentences) a person is currently hearing. It's hard to overstate the daunting character of this achievement.
The relation of speech to its physical substrate is mysterious at best. One and the same acoustic event can be experienced as different speech sounds, and different acoustic events can be experienced as the same speech sound. The perception of speech, such a commonplace event in our lives, is surely one of our most impressive and, from a scientific perspective, baffling cognitive achievments.
