Performance of the nonlinear inhibitory plasticity rule under varying postsynaptic firing rate with dynamic excitatory and inhibitory LTD/LTP threshold matching.

A. Adding noise to the postsynaptic firing rate. Top: E-to-E (wEE, blue) and I-to-E (wEI, red) as a function of time. Middle: Excitatory (, blue) and inhibitory (, red) postsynaptic LTD/LTP threshold as a function of time. Bottom: Postsynaptic rate dynamics (νE, gray) as a function of time. B. Same as A but after adding a sinusiodal input to the postsynaptic firing rate. (EPS)
