Robustness to spike time jitter. A, Mean estimation accuracy as a function of the spike time jittering for an example electrode in V1 (spontaneous activity). For each value of σ_jitter, we randomly shifted each spike train by an amount taken from a Gaussian distribution with mean of 0 and standard deviation σ_jitter (see scheme at the top). We show the mean estimation accuracy averaged across all test trials. Error bars indicate 1 SEM. r₀ denotes the estimation accuracy obtained for σ_jitter = 0. The continuous line indicates a fit with the following function: r = r₀ −

, where ₅₀σ_jitter and n are free parameters. B, For each electrode, we repeated the procedure described in A and normalized r by dividing it by r₀ (“Normalized estimation accuracy”). We show the mean normalized estimation accuracy across all electrodes (n = 88) using the electrode-specific filters. C, Distribution of ₅₀σ_jitter for all V1 electrodes recorded during spontaneous activity (n = 88). The black arrow shows the position of the example from A. The dashed vertical line indicates the mean value: the mean value of ₅₀σ_jitter was 172 ± 89 ms (mean ± SD). Bin size of 25 ms.
