Figure 4. Evaluating model complexity.

Figure 4

a) Correlation (mean ± 2 SEM for repeated measure designs) between the true and inferred spike rate comparing the STM model (black) with a flexible multilayer neural network (dark grey) and a simple LNP model (light grey) evaluated on the four different datasets collected under anesthesia/ex-vivo (with n=16, 31, 19 and 9, respectively). Markers above bars show the result of a Wilcoxon signed rank test between the STM model and the LNP model (see Methods, * denotes P<0.05, ** denotes P<0.01). The evaluation was performed in bins of 40 ms.

b) Information gained about the true spike train by observing the calcium trace performing the same model comparison described in a).
