🧠 Why Your Brain Treats a Feed Like a Tribe

Interactive 3D brain and network visualization where users adjust simulated social-media notification frequency and watch a stylized reward-circuit and tribal-alert response fire more intensely.

Neuroscience & Biophysics3DModerate60 FPS🔥 Fire

A stylized 3D brain shows a tribal-alert hub and a dopamine reward hub firing in sequence every time a simulated social-media notification arrives, illustrating why checking your phone can feel both urgent and irresistible.

🔬 What It Demonstrates

Each notification triggers the tribal-alert hub first (evaluating social threat or exclusion) and the reward hub second (evaluating whether the update is worth attending to), on an unpredictable variable-ratio schedule that mirrors real social feeds.

🎮 How to Use

Raise notification frequency and sensitivity sliders to see the tribal-alert and reward circuits fire harder and more often, isolate a single pathway with the circuit view selector, and toggle habituation to see dopamine tolerance build with repeated checking.

💡 Did You Know?

Because ancestral survival depended on a small group's approval, the brain's threat-detection circuitry treats social exclusion cues with a speed and priority similar to physical danger — a mismatch a modern feed of thousands of strangers can exploit continuously.
