a, Left, inter-neuronal firing rates between neurons in the same hemisphere in an example expert mouse. Right, mean area of inter-neuronal synchrony for all expert mice (p = 3.7e−23, signed-rank test, 867 neurons, 9 mice). b, Same as in a, but for naive mice (p = 0.87, signed-rank test, 744 neurons, 6 mice). c, Left, joint-PSTHs between neurons in same hemisphere of an example expert mouse. Right, all responsive neurons in expert mice (p = 2.3e−36, signed-rank test, 867 neurons, 9 mice). d, Same as in c, except in naive mice (p = 0.87, signed-rank test, 744 neurons, 6 mice). e, Left, within hemisphere spike–field PPC for RS cells in an example expert mouse (n = 134), Right, all stimuli responsive RS cells (p = 2.3e−11, signed-rank test, 810 neurons, 9 mice). f, Same as in e, except in naive mice (p = 0.004, signed-rank test, 743 neurons, 6 mice). g, Left, within hemisphere spike–field PPC according to horizontal location of field potential in an expert mouse (98 neurons). Right, all stimulus-responsive cells during hit stimulus (p = 1e−11, two-sample t test, 566 neurons, 9 mice). h, Same as in g, except in naive mice during HM stimulus (p = 4.7e−8, two-sample t test, 499 neurons, 6 mice). All error bars represent the mean ± s.e.m. All statistical tests were two-sided.
