The present invention relates to methods and systems for profiling evoked potentials in brain electrical activity which apply steady state response concepts to analysis of longer latency responses reflective of activity of brain regions beyond the brainstem, up to an including the cortex. The use of repeated stimuli within a single analysis window produces a quasi steady-state response and permits a high-resolution spectral analysis. Response amplitudes were measured at repetition rates from 80 to below 1 Hz, using trains of repeated tone-burst stimuli. An amplitude measure introduced and defined as the harmonic sum was incorporated into the spectral power of the response carried by both the fundamental frequency, and the harmonics thereof. Additionally, time ensemble averaging can be employed to improve signal to noise ratio.

The evoked potential processing system includes, in one embodiment, a spectral averaging method. Time based, digital pre-stimulus and post-stimulus electroencephalographic (EEG) signal streams are obtained and are converted into frequency spectrum signals. A differential spectrum is obtained. The differential spectrums from a plurality of sweeps are summed. The summed differential spectrum is then converted into a time based signal stream which contains the evoked potential (EP) signal therein. The EP signal can also be obtained utilizing a two-dimensional filter. Pre- and post-stimulus EEG signal streams for a sub-group of stimuli, wherein each stimulus in a group has the same intensity or frequency, are filtered by conventional averaging or spectral differential averaging. The time based, filtered, post-stimulus EEG signal streams are placed in an array and the array is then filtered by a two-dimensional Fast Fourier Transform (FFT) filter. The array is then filtered by a mask and the masked array is then transformed into a time based format by an inverse FFT.
