Neuromagnetic topography of photoconvulsive response in man

摘要: Abstract The neuromagnetic method was applied to the study of photoconvulsive responses. identification specific magnetic field distributions over scalp achieved by: (a) a stimulation paradigm consisting series trains flicker stimuli randomly presented epileptic patient, after eye closure, get responses while avoiding seizures; (b) novel procedure for data analysis, select consistent These patterns, when sufficiently stable in time and dipolar shape, were used source localization usual biomagnetic framework equivalent current dipole representation. results this approach suggest that different cortical areas are repeatedly activated, involving mainly frontal, occipital temporal areas, often with hemispheric prevalence.
