ABSTRACT OF THE DISCLOSURE A system for the on-line analysis and topographic display of human brain electrical activity is disclosed, it includes amplifying filtering and converter circuits for generating a plurality of signals, representing electrical activity at a plurality of predetermined data point locations on a patient's head in digital form. A first microprocessor and associated circuits preprocess the digital signals into a predetermined format, and a second microprocessor and associated topographic map generator form an image computation. A display unit receives th~ preprocessed digital signals as inputs from the image computation and display unit. The topographic map generator defines a map of a plan or elevation view of the brain containing a plurality of pixel points far in excess of the number of data points and interpolates the digital signals, so as to provide a value for each pixel on the map. The pixel information is provided as outputs in synchronism with a horizontal and vertical scan. A video monitor receives the output of the image computation as an input of a display unit.
