Abstract

Injury to brain may result in transient or time-varying changes in evoked potential (EP) signals. This paper tests the hypothesis that injury may precipitate a nonlinear response that may be irreversible. An adaptive algorithm is presented for coherence estimation from noisy, time-varying EP signal measurements. An analysis of experimental data from cats made hypoxic reveals that adaptive coherence analysis rapidly detects the injury to brain, and that injury-related response is nonlinear.
