Synaptic Pruning: Use It or Lose It (2D)

Interactive 2D Hebbian model of activity-dependent synaptic pruning: toggle which neural pathways get simulated use, watch a real Hebbian learning rule strengthen co-active synapses and weaken uncorrelated ones tick by tick, and see unused connections cross an elimination threshold and disappear.

A 2D companion to the 3D synaptic-pruning model, built around the same Hebbian "use it or lose it" rule but making the mechanism itself interactive: toggle the language, motor and visual pathways on or off to decide which parts of this simulated brain get real correlated activity, then run the developmental clock and watch a genuine per-tick Hebbian update — strength grows with co-activation, decays without it — carry synapses either to consolidation or across the elimination threshold and out of the network.

⚙ Under the hood

Adjust Hebbian learning rate and homeostatic decay. Watch synaptic pruning shape the language, motor, and visual pathways as the developmental clock runs.
