- Scientists study a psychedelic drug for mood and addiction.
- The drug can change how the brain works.
- Blood flow in the brain is a common scan signal.
- Researchers gave the drug to mice and watched effects.
- Neural firing no longer matched blood flow after dosing.
- A second medicine blocked a receptor and fixed blood flow.
- They tested another psychedelic and saw similar changes.
- Human brain scans showed similar blood-flow changes too.
- This result matters for doctors using brain scans.
