Examples of rate estimate revision and Kullback–Leibler divergence. a, b For neuron N15 shown in Fig. 1, optimized neural activity (ONA; lower panel) was calculated using transient SNA (TSNA; solid line in upper panel), shared neural activity (SNA; magenta line in middle panel), and the parameter \(\alpha\) that regularized their contributions. The dotted lines in the upper and middle panels represent the TSNA and SNA included in ONA, as determined by \(\alpha\). c, d Examples of Kullback–Leibler divergence of a single neuron (DONA) for neuron N15; pairwise Kullback–Leibler divergence of single pairs of neurons (PDONA) of the reference neurons N2 (black), N7 (magenta), and N12 (cyan) to the target neuron N15. The vertical lines demark the behavioral epochs, i.e., S: sensory epoch; D: delay epoch; and R: response epoch. Examples are the averages of all the trials in the given session. Shaded regions denote the standard error of the mean (SEM)
