ABSTRACT:
In a system for displaying multichannel EEG data, data values received from a matrix of EEG electrodes are stored in a random access memory. Digital values to be displayed are interpolated from the input values by addressing selected ones of the inputs from memory, multiplying those inputs by predetermined coefficients taken from a coefficient memory and summing the products. Each element of the display can be determined in that way within one frame time of the display apparatus. The data can be interpolated in real time for a flicker free display at a rate of over 25 frames per second. By displaying separate values associated with each display element as a distinct color, the dimensionality of the display can be increased. The numeric matrix which underlies the expanded topographic display can be stored digitally and further utilized in further operations and displays.
