The Rebus theory in the context of Ketamine therapy refers to the idea that psychedelics can temporarily relax or “unlock” the brain’s rigid belief systems and mental models, allowing for a more flexible and fluid state of mind. The acronym “Rebus” stands for “Relaxed Beliefs Under Psychedelics.”

How Does Ketamine Fit into the Rebus Theory?

Although ketamine is not a classic psychedelic like psilocybin or LSD, it shares some common features with these substances, particularly in how it alters consciousness and promotes mental flexibility. Ketamine works by blocking NMDA receptors in the brain, which play a crucial role in learning and memory. This blockage leads to a temporary disruption in the brain’s default mode network (DMN), a network of brain regions associated with self-referential thinking and high-level beliefs.
Under the influence of ketamine, the DMN becomes less dominant, allowing for a temporary “loosening” of rigid thought patterns. This effect is akin to what the Rebus theory describes as the relaxation of beliefs under psychedelics. By disrupting the usual patterns of brain activity, ketamine can help patients break free from their negative beliefs and experience new ways of thinking and feeling.

The Therapeutic Process

The Rebus theory also helps explain why ketamine treatment is often accompanied by therapeutic support. While ketamine can create a window of opportunity for change by relaxing rigid beliefs, the therapeutic process involves guiding the patient through this experience. This guidance helps the patient explore and integrate new perspectives, leading to lasting changes in their mental health.
For example, during a ketamine treatment session, a therapist might help a patient confront and reframe negative beliefs about themselves or their past. The relaxed state induced by ketamine allows the patient to approach these beliefs with a sense of curiosity and openness, rather than fear or resistance. This can lead to profound insights and emotional breakthroughs, which are then reinforced through follow-up therapy sessions.
