Visualizing the structure of the models through the dwell times in sampling.
A. Distributions of dwell times for three sample states, estimated over 104 separate instantiations of MC sampling from the full model. The persistence indices for states 1,2 and 3 were 0.092, 0.54, and 0.92, respectively. B. For the same states as in (A), distributions of dwell times estimated on shuffled (independent) data. C. Across the N = 3187 states with K = 12 spiking cells recorded in the data (M1, light) we measured the average dwell time (over 103 MC runs) in the full (red) and independent (blue) models. These are plotted vs. the PI given by the full model. Note the logarithmic scale on the y-axis. D. The persistence indices for the same group of states are estimated using the maximum entropy model fitting the natural movie in the light (x-axis) and the dark (y-axis) adapted conditions.
