The Integrate-and-Fire Neuron Model as a Sensory Neuron Model

In our previous tech brief on modeling a simple biomimetic joint, I proposed the use of the integrate-and-fire model as the model for the muscle spindle afferent sensory neurons. In the form presented previously, I used the equation for the ideal I&F neuron. In this tech brief I’d like to extend this model a bit and make it a better representative of our BAN circuit. I will also discuss some non-standard modifications to the model that make its response give a better reproduction of the biological behavior of the spindle afferent sensory neurons which produce the type Ia afferent feedback signal from the muscle spindle.
