Source localization of brain electric field frequency bands during conscious, spontaneous, visual imagery and abstract thought / D. LEHMANN in Cognitive Brain Research, 1-4 (December 1993)
[article]
Titre : Source localization of brain electric field frequency bands during conscious, spontaneous, visual imagery and abstract thought Type de document : Texte imprimé et/ou numérique Auteurs : D. LEHMANN, Auteur ; B. HENGGELER, Auteur ; M. KOUKKOU, Auteur ; C.M. MICHEL, Auteur Année de publication : 1993 Article en page(s) : p.203-210 Langues : Anglais (eng) Mots-clés : Source-localization EEG-frequency-band Mentation-class Consciousness Spontaneous-thought Visual-imagery Index. décimale : PER Périodiques Résumé : This paper addresses the issue of mind-brain correspondence, using a novel way to reduce brain electric field data in the frequency domain to estimates of intracerebral model source locations, and applying this method to brain electric data collected during the 2-s epochs immediately before the randomly solicited reports of spontaneous, conscious, covert experiences from 12 normal volunteers. The mentation reports were classified into visual imagery and abstract thought. The mean locations of the EEG model sources associated with abstract thoughts were generally more anterior and deeper than those of visual imagery, particularly significant for the delta/theta band; the finding was common across subjects. Thus, different brain functional states involving different geometries of activated neural populations exist during conscious, spontaneous, task-free mentations of the visual imagery type and of the abstract thought type.
