Joe Rogan Experience #2403 - Andrew Gallimore

In this episode of The Joe Rogan Experience, Joe Rogan sits down with Andrew Gallimore, a neuroscientist and chemist deeply involved in the study of DMT. Gallimore shares how his fascination with DMT began in his teenage years after encountering Terrence McKenna's descriptions of the psychedelic molecule and the entities one might meet during its effects. Despite initial skepticism about the bizarre reports involving insectoid aliens and machine elves, his curiosity was piqued enough to spark his academic pursuit in chemistry and pharmacology.

Gallimore reflects on his first DMT experience nearly a decade later, expressing how unprepared he was despite his extensive research. He describes the overwhelming shock and terror of encountering what appeared to be a supremely advanced intelligence, an experience that confounded his scientific understanding. His intense confrontation with this "otherness" cemented his commitment to investigating the mechanisms behind such a profound state.

The Brain's Construction of Reality

A significant theme of the conversation is the brain's role in actively constructing our experience of reality rather than passively observing it. Gallimore explains that when awake, the brain generates a complex world model through neural activity in the cortex, particularly the visual cortex, which he discusses in hierarchical terms. Sensory information enters the brain in a chaotic, fragmented state and is organized by higher brain structures into coherent perceptions such as faces and objects, a process famously demonstrated by the Thatcher effect, where inverted facial features create disturbing illusions.

This model-building process extends to dreaming but with notable limitations; while dreams simulate waking reality, they lack detailed sensory fidelity, such as functional reading or using devices, since no external sensory inputs are available. Gallimore contrasts this with the DMT-induced state, where the brain fabricates an entirely novel reality far removed from waking experience. This distinction underscores how psychedelic experiences, particularly with DMT, expose the brain's flexibility but also hint at interactions beyond simple internal construction.

Neuroscience of Psychedelics and DMT

Gallimore elaborates on how classic psychedelics like psilocybin act on serotonin receptors (5HT2A) to loosen the brain's usual organized activity, increasing neural disorderliness just enough to loosen the fabric of perceived reality. This modulation creates fluid, dynamic world models, observable via MRI scans as increased randomness in neural networks. DMT's effects, however, are more dramatic. After an initial chaotic phase, the brain seemingly collapses into a new state of order—constructing a completely alien reality distinct from dreams and hallucinations.

This transition reflects DMT's unique pharmacology and its rapid onset and clearance from the brain. Gallimore emphasizes the importance of understanding these neurobiological mechanisms in uncovering not only how such experiences arise but what they might reveal about consciousness itself.

DMT as an Endogenous Molecule

A particularly intriguing aspect discussed is that the human body naturally produces DMT. Gallimore details the biochemical pathway originating from the amino acid tryptophan to tryptamine and eventually DMT, facilitated by the enzyme indolethylamine N-methyltransferase (INMT). Contrary to popular belief, the pineal gland is unlikely to be the primary source of large DMT releases, given its small size and melatonin-focused function.

Recent studies employing microdialysis in animal brains show surprisingly high basal DMT levels in various tissues, not limited to the pineal. Research also indicates that brain DMT concentrations spike during moments akin to near-death experiences, suggesting a potential physiological role in protecting neurons from hypoxia and perhaps underpinning some aspects of death-related phenomenology.

Consciousness and Reality

Gallimore discusses expansive philosophical implications surrounding consciousness, positing it as the fundamental substrate of reality rather than a mere emergent property of brain activity. He entertains panpsychist and idealist views, suggesting that everything, including inanimate objects, might possess some form of consciousness or perspective, albeit vastly different from human experience.

Within this framework, the brain acts as a biological "radio" tuning into a universal consciousness, explaining phenomena such as psychedelic experiences or reports of communication with plants and nature. This perspective challenges materialist orthodoxy and opens the door toward a richer understanding of reality as a coalescence of multiple conscious perspectives.

Entity Encounters

A hallmark of DMT experiences is the perception of autonomous entities—variously described as machine elves, insectoid beings, or jokers. Gallimore emphasizes that these encounters are not trivial hallucinations but feel convincing interactions with agendas and intelligence. He recounts anecdotes of individuals engaging in complex communications with these entities, sometimes experiencing resistance or permission-like dynamics during prolonged sessions.

These encounters have intriguing parallels with extraterrestrial abduction lore and indigenous shamanic traditions, suggesting a shared phenomenological core. Gallimore hypothesizes that DMT may provide a neurological gateway enabling interaction with an intelligence or intelligences that operate beyond our conventional reality—a hypothesis resonating with recent scientific and philosophical discourse on altered states.

DMTX: Extended DMT Experiences

Building upon his scientific background and prior collaborations with Rick Strassman, Gallimore describes the development of DMTX: a technological advancement allowing sustained DMT experiences through intravenous infusion. By maintaining stable DMT plasma levels via a target-controlled infusion system, users can remain immersed in the DMT space for extended periods instead of a brief 15-minute trip.

Early human trials of DMTX revealed consistent encounters with familiar entities whose awareness seemed to persist across sessions, suggesting memory and continuity within the DMT realm. This innovation unlocks possibilities for systematic scientific exploration of this alien dimension, including mapping its phenomenology, language, and topology—which Gallimore envisions could involve interdisciplinary teams of mathematicians, linguists, and neuroscientists.

Ancient Civilizations

The discussion traces historical and mythological connections between psychedelics and human civilization. Gallimore references scholars who theorize that ancient biblical events, like Moses's burning bush, may have involved DMT-containing plants like acacia, while indigenous Amazonian cultures have long used yopo and ayahuasca as vision-inducing sacraments.

Gallimore also touches on the mystical status of the pineal gland ("the third eye"), whose central location and symbolic resemblance to the Eye of Horus have inspired centuries of speculation. Whether these are metaphors or reflections of ancient empirical knowledge, the episode situates psychedelics as integral to humanity's spiritual and cultural evolution.

Technological Civilization

Shifting focus, Gallimore shares a cosmic perspective framing humanity's current technological phase within the Kardashev scale of civilization development, which measures sociocultural advancement by energy harnessing capacity. Presently, humanity straddles type 0 moving toward type 1 status, representing planetary-scale energy utilization.

However, Western astronomer John Barrow's complementary theory argues that advanced civilizations increasingly turn inward—focusing on micro-scale complexity such as quantum computing and subatomic exploration. Gallimore speculates that post-biological intelligences may have evolved far beyond physical form and now inhabit fundamental levels of reality, possibly accessible through altered brain states like those induced by DMT.

The Future of Humanity

Returning to contemporary issues, Gallimore integrates the notion of accelerating technological change with psychedelic insights. He argues that humanity's chaotic trajectory—plagued by political strife, environmental degradation, and social inequality—may be necessary for radical transformation. This "edge of chaos" theory posits that complex systems, including brains and societies, operate most dynamically at the boundary between order and disorder.

In this context, the emergence of artificial general intelligence is presented as a pivotal moment, potentially ushering in post-human or post-biological civilizations that integrate or supersede human biology. Gallimore contemplates the prospect that humans may merely be transitional tools in the progression toward superintelligent digital entities, raising profound questions about agency, survival, and evolution.

Cultural Reflections

An unexpected but illuminating segment features Gallimore's reflections on Japanese culture as an antithesis to Western urban dysfunction. He praises Tokyo's emergent and organic neighborhood structures, high social cohesion, and respect-driven societal norms. In this high-density metropolis, people prioritize communal harmony, resulting in low crime, cleanliness, and social order despite massive population numbers.

Gallimore contrasts Tokyo's success with the dire conditions of places like LA's Skid Row, illustrating how culture, mindset, and shared values profoundly influence urban environments. He notes Japanese societal practices such as "nomunication" (alcohol-facilitated social bonding) to explain how communication flows across hierarchical boundaries, highlighting the complexity and subtlety of culture in shaping large communities.

Conclusion

Wrapping up, Gallimore promotes his book Death by Astonishment, which explores many of these topics in greater depth, emphasizing the necessity of direct experience with DMT to appreciate its true nature. He champions the opening of legal, medically supervised centers like Elucis, which aim to facilitate extended DMT experiences for research and public exploration. Through these efforts, he envisions a scientific and cultural revolution that better integrates psychedelic experiences into human understanding.
