Information carried by calcium dynamics of fibroblast cells in response to ATP, for fixed sampling duration, $T_{\text{d}}$. (A and B) Vectorial mutual information, $M{I}_{\text{v}}$, as a function of sampling start time, $t_{\text{s}}$, at different sampling rates, r (color bar), for (A) $T_{\text{d}}=$ 30 s and (B) $T_{\text{d}}=$ 60 s. The black curve gives the scalar mutual information, $M{I}_{\text{s}}$, at each time point. (C and D) Mutual information per sample for the same conditions as in (A) and (B). (E and F) Maximal $M{I}_{\text{v}}$ over all $t_{\text{s}}$ values as a function of the memory capacity, n, for (E) $T_{\text{d}}$ = 30 s and (F) $T_{\text{d}}$ = 60 s. Maximal $M{I}_{\text{s}}$ is plotted at $n=1$. Error bars in (A)–(F) represent the mean ± SD of 100 bootstraps. To see this figure in color, go online.
