Eigenmodes of the deep unconscious: the neuropsychology of Jungian archetypes and psychedelic experience.
Neurosci Conscious – October 18, 2025
Summary
Our brains might possess inherent patterns explaining universal symbols, like Jungian archetypes. Research investigated their neural basis, especially during psychedelic experience. Advanced neuroimaging revealed specific "eigenmodes"—fundamental brain activity patterns—strongly linked to archetypal imagery and profound insights. These findings suggest psychedelics illuminate the "deep unconscious," showing a neural substrate for universal psychological experiences and our brain's capacity for shared meaning.

Micro-phenomenology of immersion and perceived presences under DMT
PsyArXiv – May 14, 2025
Summary
The mind's capacity to create deeply immersive realities, complete with perceived "presences," is profoundly amplified by DMT. This investigation explored how individuals experience full immersion and interaction with these perceived entities. Researchers used detailed interviews to meticulously map the unfolding subjective experiences. Participants consistently described a profound sense of "being there," fully immersed in vivid, often interactive, environments. Many reported meaningful, positive encounters with perceived autonomous entities, feeling a strong sense of connection and communication. These findings offer unique insights into the brain's ability to generate complex, interactive realities, suggesting DMT can unlock profound states of consciousness where perceived presences feel remarkably real and often beneficial.

Eigenmodes of the deep unconscious: The neuropsychology of Jungian archetypes and psychedelic experience.
PsyArXiv – October 20, 2024
Summary
The brain's deep patterns may explain universal human experiences. Research suggests Jungian archetypes, like hero or shadow, correspond to specific, fundamental patterns of brain activity. Using neuroimaging during psychedelic states, scientists observed distinct neural signatures aligning with reported archetypal encounters. This powerfully indicates a biological basis for these profound unconscious structures, offering new insights into consciousness.
