The rate that the capacitor discharges is tied to the resistor that is pulling the input to the inverter to the negative.
Probably the most utilized Nv Net topology in BEAM, the Bicore consists of two neurons placed in a loop that alternates current to the output.
Other larger network topologies include the Tricore, and Quadcore which are laid out in a similar way the bicore is, except with more Neurons in the loop.
An example of this can be seen in a simple BEAM walker robot utilizing a bicore network (2 neurons).
This affected pace is often used to alter the walking gait of a robot in order to steer it based on the input from its sensors.
