Abstract:
1. A method of measuring sensory and perceptual mechanisms of the brain, and training these mechanisms with feedback, comprising the steps of: securing electrodes to a subject's scalp; displaying stimuli to the subject; receiving an electroencephalographic (EEG) signal from the subject while the stimuli is being displayed; transmitting the resultant EEG signal to a filter; narrow band filtering the EEG signal to a predefined frequency; reconstructing the total evoked brain activity by combining the filter outputs; feeding back in real-time of the total evoked response comprising at least one steady-state visual evoked potential (SSVEP) component amplitude; and monitoring, in real-time, the short-term changes in each of the SSVEP component amplitudes, for the interpretation of waxing and waning behavior to reflect variations in sensory and perceptual vigilance for use as criteria for providing feedback for at least one of training, monitoring, and assessment purposes.
