The method of claim 7 wherein particular components of the SSVEP are extracted in real-time and used to make a control decision that can result in either a change in feedback, an automated decision, a switch closure, the triggering of an actuator, or another event.ġ2. The method of claim 7 wherein the subject receives, in real-time feedback specific to particular sensory and perceptual pathways of the brain, and receives feedback, of evoked-potential components that differentially reflect waxing and waning of independent generators in the brain, with real-time information facilitating operant or learned (volitional) conditioning of the brain.ġ1. The method of claim 7 wherein auditory feedback consisting of heard sounds is employed to reflect to the subject the subject's brain response to the applied visual, wherein the feedback trains the sensory/perceptual pathways of the brain.ġ0. The method of claim 7 wherein the EEG signal is used to control a stimulator which produces a visual stimulus, wherein the control trains an increase or decrease in the evoked response.ĩ. A method of measuring sensory and perceptual mechanisms of the brain, either separately or together, 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 filtered waveform outputs feeding back in real-time of the total evoked response comprising a steady-state visual evoked potential (SSVEP) waveform and reconstructing, in real-time, an estimate of the SSVEP waveform using the combined filtered waveform outputs for dynamically tracking latency and amplitude for the measurement of sensory and perceptual mechanisms of the brain.Ĩ.

The method of claim 1 wherein the composition of harmonic activity in the SSVEP is used in real-time to provide variations in an auditory feedback signal, so that the trainee hear, separately, the brain's visual primary and secondary sensory and perceptual response mechanisms in real time via an audio amplifier for training purposes.ħ.
