Relative-coding network states cause negative reciprocity. Reciprocity as a function of \(f_{bc}\), the fraction of bicolored nodes, in networks that follow random transition graphs. Reciprocity decreases linearly with \(f_{bc}\), approaching zero as \(f_{bc}\) approaches zero. Mean ± SD are shown, n = 30 networks for each \(f_{bc}\). Networks were constructed with target FR = 0.5 spikes/ time step, and with the same number of neurons and network firing states as T + F networks constructed with \(\tau = 7\) and \(f_{r} = 4\).
