Psychedelics Don't Hallucinate - They Break Reality's Filter

New brain research shows psychedelics like LSD don't create hallucinations but instead weaken the brain's "reality filter."
A study used fMRI scans on 17 people to reveal psychedelics reduce activity in key brain hubs that build our sense of reality.
This could lead to better mental health treatments by safely mimicking the brain effects of trips without drugs.

Researchers at University College London ran brain scans on volunteers given LSD and found it disrupts the brain's predictive coding system, which normally filters sensory data to create a stable reality. Instead of inventing hallucinations, psychedelics let raw sensory chaos flood in, explaining the trippy experiences. The study matters because it challenges old ideas about psychedelics and opens doors to non-drug therapies for depression and addiction.
