Nonlinearcircuits Neuron / Difference Rectifier

Excerpt from description of the neuron circuit:

The neuron is from "A general purpose analog neural computer" by P. Mueller et al and modified for use in a synth. The circuit is an "idealized version of a typical biological neuron." It feeds thru the postive rectified portion of the input signal and mixes that with positive and negative going pulses (or spikes or gates) when the threshold (set by the offset pot ) is crossed. The 1st op amp stage is a summing rectifier. This stage output is fed to a comparator, the inverted positive rectified signal and the comparator output, via an attenuator, are summed and inverted at the final output stage.
