Selected neuron V—

Each node is a leaky integrate-and-fire neuron: its membrane potential V decays toward rest and accumulates external drive plus synaptic current. When V crosses threshold, the neuron spikes (flashes), resets, and enters a refractory period. A spike propagates along its outgoing synapses, adding (excitatory, pink) or subtracting (inhibitory, blue) weighted current from connected neurons. Tap any node to inject a stimulating pulse directly.
