Cannabis Compound THC Disrupts Brain Network Communication
Researchers have discovered that a moderate dose of THC, the psychoactive component in cannabis, lowers connectivity between key brain networks in young adults.
This change, visible on brain scans, may help explain the effects of cannabis use on mood, attention, and perception during intoxication.
A new study published in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging provides evidence that THC weakens communication between brain networks in young adult users.
- Even a moderate dose of THC reduced internal connectivity in brain circuits responsible for emotional regulation.
- Bodily awareness, sensory processing, and higher thinking were also affected.
The findings help explain the mental and behavioral changes experienced by many people when intoxicated with cannabis.
