Religious and Mystical Experiences as Artifacts of Temporal Lobe Function: A General Hypothesis

Mystical and religious experiences may arise from brief, electrical microseizures in deep temporal lobe structures, particularly the amygdala and hippocampus. The specific brain regions involved shape the content of these experiences, such as out-of-body sensations, distortions of time and space, intense meaningfulness, and dreamlike scenes. While cultural context and personal history influence details, shared temporal lobe properties across humans produce cross-cultural similarities. These experiences exist on a continuum from mild daily highs to intense, recurring religious conversions. Predisposing factors include genetic or biochemical conditions that increase temporal lobe instability. Life crises and near-death situations are common triggers. Because these microseizures activate brain reward regions and reduce death anxiety, they can become learned responses to existential trauma, powerfully shaping human behavior.

Abstract

Mystical and religious experiences are hypothesized to be evoked by transient, electrical microseizures within deep structures of the temporal lobe. Although experiential details are affected by context and reinforcement history, basic themes reflect the inclusion of different amygdaloid-hippocampal structures and adjacent cortices. Whereas the unusual electrical coherence allows access to infantile memories of parents, a source of good expectations, specific stimulation evokes out-of-body experiences, space-time distortions, intense meaningfulness, and dreamy scenes. The species-specific similarities in temporal lobe properties enhance the homogeneity of cross-cultural experiences. They exist along a continuum that ranges from "early morning highs" to recurrent bouts of conversion and dominating religiosity. Predisposing factors include any biochemical or genetic factors that produce temporal lobe lability. A variety of precipitating stimuli provoke these experiences, but personal (life) crises and death bed conditions are optimal. These temporal lobe microseizures can be learned as responses to existential trauma because stimulation is of powerful intrinsic reward regions and reduction of death anxiety occurs. The implications of these transients as potent modifiers of human behavior are considered.
