Distributions of preferred intervals (PI) and preferred serial order (PS) for cells and LFPs simultaneously recorded in the same electrode. A, Distributions of PI for spiking activity (black line) and β (left) or γ (right) LFPs (red line) that were tuned to interval. B, Distributions of PS for spiking activity (black line) and β (left, red line) or γ-band oscillations (right, red line) that were tuned to serial order. C, Distributions of the difference in PI between spikes and LFPs for the β- (left) and γ-band (right). D, Distributions of the PS difference between spikes and LFPs for the β- (left) and γ-band (right).
