Researchers discover that marijuana users may have false memories.
Sometimes, our brains can trick us into remembering things that never happened.
These memory 'mistakes' are seen more frequently in psychiatric disorders and old age – and now researchers have revealed why they are also more common in cannabis users.
Using neuroimaging, researchers discovered that the brains of heavy cannabis have a less active hippocampus compared with the general population.
This is part of the brain that is responsible for storing and retrieving memories.
The study was conducted by the Biomedical Research Institute of Hospital de Sant Pau and the Autonomous University of Barcelona.Related Posts: "Even Casual Use of Marijuana Can Cause Brain Abnormalities"
