Temporal resolution of spike coding in feedforward networks with signal convergence and divergence

Decoding analysis of a noisy 4 Hz + 20 Hz stimulus
(A) The 5-layer network receives a sum of sines corrupted by noise, but is trained to encode the noiseless version at the output. The decoding is done with respect to the noiseless stimulus. (B) Decoding accuracy from spikes binned at resolution Δt, in each layer of the 5-layer model. Each gray trace represents an individual network seed. Black traces are the means across all network seeds (top). Distribution of slopes of best line fits to the R2 v.s. Δt curves (bottom). (C) Slope distributions versus layer. Results are shown for 25 independent network simulations.
