Each of the neurons is scattered in the plane and wired to its k nearest neighbors, forming an undirected dendrite graph. When a neuron fires it lights up, spawns a pulse along a random subset of its connections, and enters a short refractory (cooldown) period during which it cannot re-fire. Each pulse travels at a duration proportional to the edge length divided by the pulse-speed setting; on arrival it flashes the target neuron and, with high probability, triggers it to fire in turn — this is how activity cascades across the network. A depth counter caps any single chain at 4 hops so one spontaneous spike can't loop forever.
- Graph: k-nearest-neighbor, rebuilt live when k or neuron count changes
- Refractory period: ~0.35–0.65 s per neuron after it fires
- Cascade probability on arrival: 85%, depth-limited to 4 hops
- Spontaneous firing: a random neuron fires every ~0.12–0.34 s when enabled
