Single-sweep EEG analysis of neural processes underlying perception and production of vowels.

This single-sweep electroencephalographic study using independent component analysis was conducted to determine the neural processes underlying both speech perception and production of vowels. The same neural processes located in auditory and motor areas of the brain that significantly distinguish between a speech production and a control mental rehearsal task were found for both auditory evoked responses and speech planning responses. Thus identifying common task dependent neural processes underlying speech production and perception.
