Sensors should increment a sensory neuron State, not fire it

[jurkstas]

Sensors use PingNeuron() to stimulate cennectome. This approach forces neurons in question to fire completely disregarding state of the neurone. Also, there is no way to include weight of the stimuli. Using AddToNextState() or similar function to "charge" a sensory neuron might represent biological behavior more accurately: neuron would fire whenever it has cumulated certain State and sensory data would increment the State more rapid.

This issue becomes apparent when trying to use weak sensory signals (real worm can sense huge dynamic range of certain chemicals).

P.S. amazing project!
