A method of analyzing individual cortical responses to auditory stimuli

Abstract A method is proposed which quantifies the degree to which a specified response is present in each single acoustic stimulus. The specified response is described by a second order linear differential equation. This wave form is preset in a function generator. The EEG and this template are multiplid in an analog computer. The second integral of these products is read out on an EEG oscillograph as the degree to which the specified response is present. The variables involved in this analysis are discussed.
