Note that in this example the neuron's state can fall below zero due to its inertia. Short but strong impulse gives similar results to a weak and long one. Later signal changes do not influence the output. Neuron properties can be changed by some special genotype elements inside neuron descriptions. In each simulation step, the neuron state is modified towards the value calculated from input excitations.
Force determines how fast the value is changed.
Maximum value of 1.0 gives instant reaction. Low Inertia values have very little influence on the state. Slow state change. Note the instant reaction after the input signal pulse when inertia is disabled. Final state is achieved after several oscillations.
