Hodgkin-Huxley action potentials spreading across a 2D neural sheet
Threshold0.35
Refract Period5
Coupling0.4
Modeled after excitable media — the foundation of action potential propagation. Each neuron follows a simplified Hodgkin-Huxley rule: a resting cell fires if enough neighbors are active (excitation), then enters a refractory period (cannot re-fire), then recovers. This produces travelling waves, spiral reentry patterns, and target waves — the same phenomena seen in cardiac tissue and cortical spreading depression.
