The conceptualization of the ongoing neuroelectric activity as a stochastic time series has provided a framework for the utilization of the small computer in the laboratory. Laboratory computers provide extensive computational, filing, and control capabilities which are being incorporated into the routine investigation of neurophysiological phenomena. The computational procedures implemented include both time and frequency domain techniques. Equipment utilized includes special-purpose digital computers, general-purpose minicomputers, and minicomputers with graphics capability used as intelligent terminals to larger machines.
