From: Anterior-posterior gradient of plasticity in primate prefrontal cortex
Receiver operating characteristic analysis. a, b ROC values are plotted along the Anterior-Posterior axis of the dorsal prefrontal cortex before and after training (n = 3040). Each ROC value was obtained in a 250 ms bin across time, and at across the AP axis, and then smoothed with a Gaussian. Cue presentation is indicated between horizontal lines spanning the time interval of 1.0–1.5 s in the plot. First delay period spans the interval of 1.5–3.0 s. This is followed by the sample stimulus (both match and nonmatch pooled together). c Difference of pre- and post-training stages. d Each point represents the mean ROC value of the 250 ms bins tiling the delay period of each individual neuron, prior to training. Line represents linear regression. e ROC values of each neuron, during the delay period, in recordings obtained after training. Total sample size, n = 3040 neurons
