"The “rotational waves” come from population activity looping through a stable subspace while a phase wave moves across the cortex.

In field terms, it’s a torsional coherence cycle, rotation in abstract state-space mirrored by a traveling wave in tissue. The same pattern re-aligns the brain after distraction.

Put simply: when focus returns, the brain doesn’t just switch back on, it spirals back into tune, like sound waves re-forming harmony after interference."
