Figure 1

A schematic diagram suggesting the connections for a two-layer neuron network such that the firing rate of a secondary, coincidence neuron will vary proportionately more than the variance of a set of primary neurons. The input dendrite structures to the primary neurons may be absent when those neurons act as the sensory detector elements, as is the case for the warmth–cold systems (8).
