Efficient “Communication through Coherence” Requires Oscillations Structured to Minimize Interference between Signals
Figure 3
Comparison of optimized and biologically plausible gain modulations.
(A) Blue trace is the gain modulation generated by the optimized receiving network; brown trace is a gain modulation that oscillates around zero with the same waveform as the firing rate modulation of the target. (B) Frequency response of the filter that transforms the firing rate modulation of the target input into the optimized gain modulation. (C) Comparison of Fisher information for receiving networks using optimized and alternative gain modulations.
