From: Anterior-posterior gradient of plasticity in primate prefrontal cortex
Variability and correlation. a Fano factor values based on spike counts in the delay period are plotted along the anterior-posterior axis of the dorsal prefrontal cortex before training. Line represents linear regression. b Fano factor values in the ventral prefrontal cortex. c, d Fano factor values after training. Total sample size in panels (a–d): n = 3508 neurons. e Spike-count correlation values computed during the delay period are plotted along the anterior-posterior axis of the dorsal prefrontal cortex before training. f Spike-count correlation in the ventral prefrontal cortex prior to training. g, h Spike-count correlation values after training. Total sample size in panels (e–h), n = 4668 pairs of simultaneously recorded neurons from separate electrodes, spaced 0.5–1 mm apart
