Abstract : A data acquisition, analysis and display system for time-shared use by a group of neurophysiological investigators is described. Applications of spectral analysis to a normative library of EEG data in states of sleep and wakefulness is described, with establishment of baselines for adult males in the course of simple alerting, vigilance task performance and in visual discriminations of increasing difficulty. Simple pattern recognition techniques were applied to such data from individual subjects, with good accuracy in automated recognition of EEG states accompanying different levels of focused attention. The use of computer analysis in analysis of intraneuronal wave records is described, and a physiological model of genesis of the EEG in a population of neuronal wave generators having independent and nonlinear characteristics is discussed. Possible future trends in electrophysiological data analysis are reviewed. (Author)
