Why Instagram Can Resemble Heroin To The Brain
- The brain treats social media like intoxicants because both trigger large bursts of dopamine in the nucleus accumbens.
- Chronic overexposure downregulates dopamine signaling, producing a dopamine deficit state that drives compulsive use and withdrawal symptoms.
Rats Took Selfies Showing Social Feedback Is Reinforcing
- Researchers in France rigged rats to take selfies and found rats would repeatedly take selfies even without sugar pairing, suggesting self-image cues are reinforcing.
- Anna Lembke used this study to illustrate how visual/social feedback alone can be addictive.
How The Brain Compensates For High Dopamine Hits
- Intoxicants work by releasing large, rapid dopamine bursts unlike natural rewards, forcing the brain to compensate by lowering baseline dopamine transmission.
- That compensation (reduced receptors/ transmission) produces withdrawal and increased need to use just to feel normal.
