Study shows how LSD interferes with brain's signalling

Scans of volunteers who took acid shows it disrupts information pathways in brain

A group of volunteers who took a trip in the name of science have helped researchers uncover how LSD messes with activity in the brain to induce an altered state of consciousness.

Brain scans of individuals high on the drug revealed that the chemical allows parts of the cortex to become flooded with signals that are normally filtered out to prevent information overload.
