a, Schematic illustrating the spike–field pairwise phase consistency analysis. b, Interhemispheric (IH) spike–field PPC for fast and regular-spiking cells in expert mice (FS cells: 138, RS cells: 455, 7 mice, p = 8.9e−9, one-way ANOVA) and naive mice (FS cells: 78, RS cells: 287, 4 mice, p = 0.33 one-way ANOVA). c, Percent decrease in PPC between supragranular and infragranular field potentials in expert mice (FS cells: 138, RS cells: 455, 7 mice, p = 0.73, one-way ANOVA) and naive mice (FS cells: 78, RS cells: 287, 4 mice, p = 0.95, one-way ANOVA). d, IH spike–field PPC according to laminar location of neuron and using the infragranular field potential. Expert mice—41 neurons in layer 2/3, 103 in layer 4, 205 in layer 5 and 106 in layer 6. Naive mice—55 neurons in layer 2/3, 84 in layer 4, 118 in layer 5 and 30 in layer 6. e, Left, histogram of spike–field phase relationships in an example neuron for hit and CR trials. Right, change in phase preference between hits and CR in population of RS cells of expert mice shown in degrees (p = 2.7e−7, signed-rank test, n = 323, 7 mice). All error bars represent the mean ± s.e.m. All statistical tests were two-sided.
