a Snapshots of the Allen Neuropixels visual coding dataset showing spiking activity (vertical bars), and LFP oscillations filtered in the gamma band (50–250 Hz, blue line) and theta band (3–5 Hz, orange line) for one trial of the flashes stimulus in the mouse primary visual area (V1). b Same as (a) but for the latero-medial visual area (LM). c Time-frequency spectrograms of the LFP traces in V1, after detrending the aperiodic component. d Same as (c) but for the LM. e Theta phase–gamma amplitude comodulogram during flash-evoked bursts in V1. f Distribution of Hilbert phases at each spike time during evoked theta bursts in V1 (n = 830, 723). g Median performance across mice when predicting V1 spikes from LM spiking activity using reduced-rank regression during evoked theta bursts (dark circles) and non-burst activity (light triangles). Error bars depict the upper and lower quartiles across 9 mice. Source data can be found in Supplementary Data 1.
