A new theory is reshaping how we understand psychedelics and the brain. It proposes that substances like psilocybin and LSD may temporarily empower the right hemisphere. The model, called HEALS (Hemispheric Annealing and Lateralization Under Psychedelics), suggests this shift could heighten empathy, creativity, and emotional intelligence. This could advance therapeutic use of psychedelics, according to researchers and clinical observers.
For Thailand and much of Asia, where mental health stigma and treatment gaps persist, these findings carry meaningful implications. Thai authorities are already exploring innovative approaches to mental wellness, including careful consideration of traditional therapies. Global advances on neuroplasticity and mindful healing are increasingly relevant to Thai care providers and patients.
HEALS moves beyond the simple left-brain/right-brain divide. Under typical conditions, the two hemispheres work together: the left brain tends to control analysis, attention to detail, and step-by-step tasks, while the right brain processes holistic perception, emotion, and social cues. The HEALS theory argues that psychedelics disrupt this balance, releasing right-hemisphere activity from left-brain inhibition.
One senior researcher at a renowned U.S. university explains that psychedelics can create a neural harmony between different ways of perceiving the world. Neuroimaging shows increased activity in the frontal areas of the right hemisphere during altered states, suggesting a shift toward social insight and emotional clarity.
This rebalancing appears to correlate with reported experiences of deeper empathy, psychological flexibility, insight, and creative problem solving. The theory combines neuroimaging data, clinical observations, and comparisons with other altered states such as deep meditation and trance. The Journal of Psychopharmacology has published analyses that frame these ideas within a broader context of brain networks and behavior.
Understanding how each hemisphere processes reality helps explain the effects. Damage to the right hemisphere can limit spatial awareness and social perception, while left-hemisphere damage may reduce detailed analysis but leave broader awareness intact. The HEALS researchers draw a parallel between these patterns and psychedelic experiences, noting similarities in how the brain reorganizes during altered states.
Traditional explanations of the psychedelic state emphasized a general release of cognitive control due to reduced frontal-lobe regulation. HEALS emphasizes a more nuanced rebalancing: lifting some left-brain inhibition to reveal enhanced right-brain functions that underlie the distinctive mental and emotional breakthroughs reported in studies and rituals.
Neuroimaging supports this view, with right-leaning activity seen after psychedelic ingestion. Right-frontal regions show increased blood flow and metabolism, linked to social cognition, emotional clarity, and a broader attentional focus. Users often report heightened connection, harmony, and self-insight.
Interestingly, the HEALS model aligns with findings from long-term mindfulness practice. Meditation practitioners show strengthened right-hemispheric networks, hinting that psychedelics might offer a rapid path to some benefits that meditation builds over years. With careful follow-up and safeguards, researchers suggest these gains could be sustained and enhanced.
The Thai context adds a unique layer. Mindfulness and Buddhist meditative traditions ground much of Thai mental wellness culture. The potential of scientifically guided therapies that enhance compassion and social connectedness resonates with local priorities. Universities and hospitals in Thailand increasingly collaborate with international research groups on mental health innovation, signaling broad interest in combining old wisdom with new science.
Despite optimism, experts urge caution. The neuroscientist behind HEALS cautions against relying on a single model to explain brain function. Ongoing imaging and clinical trials are essential to clarify how neural activity, consciousness, and therapy intersect.
Global developments are notable. In the United States and parts of Europe, supervised psychedelic therapies are edging toward broader approval for depression, PTSD, and end-of-life anxiety. In Thailand, anxiety and depression remain leading causes of disability, making safe, evidence-based approaches to mental health a priority. Thailand’s health authorities emphasize careful regulation and robust safeguards as research advances.
Cultural and regulatory realities must be navigated. Psychedelics remain tightly controlled under Thai law. Any move toward research or clinical use would require consultation with medical authorities, Buddhist communities, mental health professionals, and policymakers. Yet the growing international evidence base and Thailand’s openness to mindful practice create a foundation for thoughtful dialogue.
Historically, Thailand has a rich tradition of herbal healing and spiritual care, with a long-standing interest in mental well-being. Contemporary urban centers host meditation retreats and mindfulness programs that attract large participation, reflecting a broad desire for well-being and self-understanding. These threads may help local audiences relate to advances in right-brain research.
Moving forward, Thailand can explore practical applications that respect culture and safety. Right-brain empowerment concepts could influence education, workplaces, and clinical care—aiming for deeper learning, better empathy, and more collaborative problem-solving. Careful safeguards and ethical oversight will be essential.
Thai readers can contribute to the national conversation by engaging with mindfulness and emotional intelligence practices. Mental health professionals, educators, and policymakers should monitor international research, participate in ethical discussions, and seek collaborative opportunities with neuroscience communities abroad.
For those living with mental health challenges, the priority remains seeking care from licensed professionals in appropriate settings. As research evolves, Thailand’s blend of tradition and science may pave a thoughtful, culturally grounded path toward holistic well-being.
