Averaging, spatio-temporal mapping and dipole modelling of focal epileptic spikes.
A computer-based technique is described for the acquisition, spatio-temporal mapping and dipole modelling of epileptic spike events. Spike acquisition is operator-controlled and subsequent data processing is performed off-line. Preliminary averaging and topographical display of wave forms provide complementary information on the spike field. The method promises to be a useful adjunct to conventional EEG in spike analysis.
