Brain networks shaping religious belief

Area of Science:

• Neuroscience
• Cognitive Science
• Psychology of Religion

Background:

• Previous fMRI studies identified three cognitive dimensions of religious belief linked to specific brain regions.
• The causal relationships and directional flow within and between these networks remained uninvestigated.

Purpose of the Study:

• To examine the causal flow within and between brain networks associated with religious belief.
• To test if theory of mind (ToM) regions drive non-ToM regions in religious cognition.
• To investigate if differences in directional brain connectivity correlate with religiosity levels.

Main Methods:

• Multivariate Granger causality analysis applied to fMRI data.
• Examined directional connectivity within and between brain networks underlying religious belief.
• Mapped cognitive dimensions of religious belief to specific neural pathways.

Main Results:

• Supported hypotheses that ToM regions are upstream and drive non-ToM regions, and connectivity differences correlate with religiosity.
• Religious individuals showed preferential pathways from inferolateral to dorsomedial frontal cortex for monitoring supernatural agent intent (intent-related ToM).
• Beliefs based on doctrine engaged language areas (Broca's to Wernicke's), while experiential beliefs involved imagery and fear regulation pathways.

Conclusions:

• Granger causality analysis reveals the causal binding of brain regions in religious belief processing.
• Neural pathways for monitoring supernatural agent intent and processing doctrine differ based on religiosity.
• Brain connectivity patterns provide insights into the cognitive underpinnings of religious belief and experience.
