An optimization algorithm for hurtless location of epilepsy foci

Summary form only given. To determine painlessly the location of epilepsy foci the authors always adopt a method which solves the EEG or EMG inverse problem with the model of equal current dipoles. The optimization algorithm used has a great effect on the validity of the computed results. This paper proposes a kind of genetic algorithm (GA) which aims at correcting defects of previous optimization algorithms. At the same time, the authors have located foci of several epileptics by collecting multi-channel EEGs. The result shows that GAs have certain practical benefits in the painless location of epileptic foci.
