A program is presented which allows the digital integration of evoked responses. Initially the operator has the possibility of displaying the averaged response and controlling its characteristics. Afterwards, input data are provided as: (1) number of recording electrodes; (2) number of levels, initi

β¦ Synopsis
Three LINC programs are described which can be used to calculate and display several statistical indicators of a sampled cortical evoked potential waveform. These indicators are: the sample averages, the sample variances, means and variances of the peak value of the initial phase (between 10 and 20 msec following the stimulus) and its latency, and a running plot of both the average and the variance of the peak values of a moving set of 16 consecutive evoked potentials from a total run of a maximum of about 900.

We have developed a computer program for Wiener filtering of evoked potential data. The basic algorithm involves computation of the difference between the power spectrum of the sweep sum and the sum of power spectra of individual sweeps. Power spectra axe computed by means of the discrete Fourier tr
A computer program for the PDP-12 is described that reduces a series of discrete time points representing an evoked potential to a set of fundamental waveform specifications in amplitude, latency, duration, etc., for principal potential deflections or waves. To derive a basis function the program as
A sequence of three programs is described for the collection and subsequent analysis of auditory evoked potentials using a PDP-12 computer. The first program (AVEF) controls stimulus generating equipment, and collects, tags, displays, and stores individual responses. The second program (SUPRSNAP) pe
