Evidence from studies on long-range horizontal connections and traveling waves within the neocortex supports the fact that neural signals can travel significant distances intracortically without needing to pass through white matter tracts.

The analysis

The retrieved papers include studies showing that long-range horizontal connections within the neocortex mediate intracortical communication and shape intrinsic traveling waves, confirming the claim.
