Mutual information analysis. a Mutual Information values based on spike counts in the 1.5 s of the delay period are plotted along the Anterior-Posterior axis of the dorsal prefrontal cortex before and after training. Each point represents the Mutual Information value of one neuron, prior to training. Line represents linear regression. b Mutual Information values in the ventral prefrontal cortex. c–d Mutual information values after training. Total sample size, n = 3508 neurons
