Comes with the Cybernetics skill in Illos Pro, not as a file. On a machine signed in with Pro, ask your agent for it, for example: "Add the Cybernetics brain to our hero".

## How it moves

1. a neuron reaches its threshold and fires.
2. the spike runs along its axon to the next neurons.
3. the cascade spreads and fades, and the cortex around it warms.
