Provided is a method for mapping a neural area involved in speech processing, including applying a plurality of recording electrodes to a surface of a cortex of a human subject, presenting a plurality of auditory stimuli to the subject wherein some of the plurality of stimuli are speech sounds and others of the plurality of auditory stimuli are non-speech sounds, recording brain activity during the presenting of the plurality of auditory stimuli, and identifying one or more brain areas wherein activity changes more after presentation of speech sounds than it does after presentation of non-speech sounds, wherein the human subject does not speak during the presenting and the recording. Also provided is a method for mapping a neural area involved in speech production wherein the human subject does not speak during presenting speech stimuli and recording neural activity.

Rapid mapping of language function and motor function without subject participation

The present invention includes a responsive neural stimulator having electrodes, a filter, a processor, a recording medium, an extractor for extracting instantaneous voltage amplitudes of biased oscillatory activity with asymmetrically distributed peak/trough amplitudes, and a neural stimulator connected to the processor configured to apply neural stimulation via the neural stimulator when a predetermined state of neuronal excitability is detected, a state of relatively higher neuronal excitability corresponding to a relatively lower instantaneous voltage amplitude extracted by the extractor. Also provided is a system for providing neurofeedback including electrodes, a filter, a processor, a recording medium, an extractor for extracting instantaneous voltage amplitudes of biased oscillatory activity with asymmetrically distributed peak/trough amplitudes, and an output device configured to communicate changes in, increases in, decreases in, or maintenance of instantaneous voltage amplitudes, or any combination, to a participant in a neurofeedback session.
