Balance of excitation and inhibition.

Abstract

(a) After learning in the simulation using the DVS stimulus, the excitatory (red) and inhibitory (blue) currents into an example neuron are tightly balanced, with inhibition lagging slightly behind excitation. (b) Cross-correlation between the excitatory and inhibitory currents in (a). The inset corresponds to the central peak with the same axes units. The currents are strongly correlated with a small time lag of 1.5 ms.</p
