Robin Carhart-Harris - The Central Importance Of Psychological And Neurobiological Connectedness

Psychedelic-assisted therapy acts through the reduction of ego-defenses, fostering a sense of psychological and neurobiological connectedness. Psilocybin, through its agonist action on the 5-HT2A receptor, facilitates acute plasticity, which is a state of malleability where therapeutic outcomes are optimized by environmental context. This process promotes a shift towards a state of interconnectedness, helping individuals move past rigid, depressive thought patterns. Interconnectedness manifests as a unity with the self, with others, and with the world. This experience, often described as an emotional release or "breakthrough," is a central predictor of long-term depression relief. By moving beyond pharmacological reductionism, this framework incorporates personality traits, set, and setting as key components in the therapeutic journey.
