PC based EEG mapping system

Abstract

A PC based program has been designed for analysis of EEG data using brain electrical activity mapping technique. It operates under control of MS-DOS operating system and can be used as a stand alone program or incorporated into a digital EEG system. The program can apply different map interpolation algorithms from nearest neighbours methods to spherical spline functions. It performs analyses in the time and frequency domain. It applies different mapping parameters like amplitude, spectral values and a new one - first time derivative of amplitude. The program is being successfully used in clinical tests of epilepsy and Parkinson disease in our laboratory.
