Allen Brain Observatory Neuropixels data and causal manipulation show that narrowband gamma (50–70 Hz) propagates and synchronizes from LGN through V1 and multiple higher visual areas of the awake mouse, with ON- versus OFF-preferring LGN neurons firing at distinct NBG phases aligned across the cortical hierarchy — providing a cross-area phase code for visual features.

15. Methodological limits and emerging tools — what current mouse-cortex tools cannot yet measure about E→E recurrence (subthreshold network activity, fast plasticity in vivo, millimetre-scale dynamic connectomes), and what is on the near horizon
