Neural correlates of mystical experience

Area of Science:

• Neuroscience
• Cognitive Psychology
• Psychiatry

Background:

• Mystical experiences are widely reported across cultures and history.
• Previous theories suggest executive brain functions underpin these experiences.
• Causal links require structural brain lesion studies, which have been limited by small samples or inadequate cognitive measures.

Purpose of the Study:

• To investigate the causal relationship between brain injury and mystical experiences.
• To identify specific brain regions involved in modulating mystical experiences.
• To test the hypothesis that executive functions down-regulate mystical experiences.

Main Methods:

• Voxel-based lesion-symptom mapping analysis was conducted on participants from the Vietnam Head Injury Study.
• 116 participants with penetrating traumatic brain injury (pTBI) were compared to 32 matched healthy controls (HC).
• Lesion locations in frontal and temporal regions, including the dorsolateral prefrontal cortex (dlPFC) and temporal cortex (TC), were analyzed in relation to mystical experience scores.

Main Results:

• Lesions in frontal and temporal brain regions were significantly associated with increased mystical experiences.
• Specifically, damage to the dorsolateral prefrontal cortex (dlPFC) was linked to markedly increased mysticism.
• Longitudinal analysis of pre-injury data ruled out pre-existing individual differences in cognitive function.

Conclusions:

• Findings support the role of executive brain functions in mystical experiences.
• Executive functioning, particularly involving the dlPFC, causally contributes to the down-regulation of mystical experiences.
• This research provides neurobiological evidence for the modulation of profound subjective states by specific brain regions.
