Signal Processing and Characterization of the Audio Evoked Cortical Response.
Russell Eugene. McWey · Calhoun: The Naval Postgraduate School Institutional Archive (Naval Postgraduate School) · 1974
The audio evoked cortical response to stimuli consisting of audio "clicks" of varied frequency was analyzed. Analysis of the encephalogram was accomplished through the use of a computer based signal processor which used signal averaging as the primary processing mode to produce a signal for analysis. A "unit response" wave form was identified and its relationship to the composite response to multiple stimuli was investigated. Using the unit response as a criterion with multiple audio click stimuli, concepts of initial reaction time and integrative processing were identified.
