Mediumship and spirit possession are cultural phenomena found worldwide. The Spiritism, popular in Brazil, is a religious tradition that emphasizes mediumship. The "absorption hypothesis" (the association of marked increases in focused attention with concomitant decreases in self-awareness) is one of the neuropsychological explanatory theories for these experiences. We measured electroencephalographic (EEG) spectral power in frontal electrodes within theta, alpha and beta bandwidths, as well as cross-regional cortical coherences, in female Spiritist experienced mediums (n = 10) and in female non-medium control subjects from the same religious context (n = 10). Scalp EEG signals were captured simultaneously from participants in each of the two groups in three different moments: before, during and immediately after mediumistically speaking. Compared to non-medium controls, the mediums had greater beta power on some electrodes in all phases of the experiment, greater theta power on one electrode at the communication phase and greater alpha power on one electrode at the post-communication phase. No condition effects (within-group comparisons) were detected in any group. No group effects were noted for cross regional cortical coherences. No ictal EEG pattern was observed, except for one participant in the mediums group. These findings support the hypothesis that absorption could have a mechanistic role in anomalous sensorial experiences such as mediumship. The coherence pattern in mediums during the anomalous experience differed from prior studies on pathological dissociation and on hypnotic states. Cognitive control processes seem to be engaged during the anomalous sensorial experiences.Bastos Jr. MAV et al. / Arch Clin Psychiatry. 2016;43(2):20-6

“…Human learning relies upon neuronal systems related to separable brain structures: explicit (mediated by frontal and medial temporal lobe) and implicit/procedural learning (mediated by striatum and prefrontal areas) [3]. Subjects under hypnosis show disruption in internal (prefrontal and precuneal areas), external (lateral frontoparietal regions) brain networks, and sub-cortical areas [4]. Studies have shown enhancement of learning performance associated with the use of hypnosis in healthy subjects that could be attributed to the disruption of attentional control and the executive system involved in learning processing [3].…”

RésuméLe cancer et ses traitements ont de nombreux effets secondaires :d ouleurs, fatigue, difficultés de sommeil, nausées, vomissements, bouffées de chaleur,d é tresse émotionnelle. Ces symptômes impactent négativement la qualité de vie des patients et perdurent souvent pendant des années après les traitements. Malgré la difficultéàtraiter ces effets secondaires au moyend 'approches pharmacologiques, l'hypnose as ouvent été laisséed ec ôté en oncologie. L'hypnose est définie comme un état de conscience modifié au cours duquel des processus d'attention et de concentration focalisées permettent au sujet une absorption dans son monde intérieur associée à une relative mise en suspens de la conscience de l'environnement. Durant cette procédure, un professionnel suggère au patient des changements dans ses sensations, perceptions, pensées ou comportements. Plusieurs études ont mis en évidence l'efficacité de l'hypnose pour diminuer la douleur provoquée par les traitements et procédureso ncologiques. L'hypnose est également utile dans le cadre de la gestion de la fatigue liéea uc ancer.D es interventions combinant hypnose et thérapie cognitivocomportementale ou auto-bienveillance ont montré des effets positifs à ce niveau. Para illeurs, l'hypnose permet une amélioration de la détresse émotionnelle liéeaux procédures médicales et du bien-être psychologique général, ainsi qu'une diminution de certains symptômes physiques comme les nausées et les bouffées de chaleur.L es techniques de neuro-imagerie mettente né vidence des processus cérébraux spécifiques à l'état d'hypnose. Nous pouvons ainsi mieux comprendre les mécanismes sous-jacents aux modifications comportementales rapportées par les patients qui bénéficient de l'hypnose dans leur prise en charge. Mots-clés
