Stimulus-dependent Maximum Entropy Models of Neural Population Codes
Figure 10
Surprise and information transmission estimated from the pairwise SDME (S2) model.
(a) Surprise rate (blue) is estimated from the static ME and S2 models assuming independence of codewords across time bins. The instantaneous information rate (red) is the difference between the surprise and the noise entropy rate, estimated from the S2 model (see text). The information transmission rate is the average of the instantaneous information across time. (b) Population firing rate as a function of time shows that bursts of spiking strongly correlate with the bursts of surprise and information transmission in the population. (c) The stimulus (normalized to zero mean and unit variance) is shown for reference as a function of time.
