  • Abstract
  • Look Inside

A computer-aided method, dipole tracing system, allows to estimate the location of the generator of brain potentials and has the advantage of non-inva-sive recording in physiological state. In this experi-ment, a two-dipole model and a four-dipole model of the active electrical sources of the cognitive component P300 of event related potentials have been examined by using dipole tracing method innormal human subjects. We have recorded P300 in a group of 3 healthy females aged 19-24 years, using somatosensory stimuli requiring a button-press response.
