neuron

The surface of one neuron in the brain's instanced neuron cloud. It lights itself from the instance data the brain's integrate kernel writes each step (lane 0: activity trace, normalised membrane, spike flag) and the class colour the module writes once (lane 1): dim at rest, brighter as the membrane depolarises, flaring to full emission on a spike and fading with the trace. rest_brightness, membrane_brightness and spike_brightness set those three levels on the material.
