The authors took two half-second windows before the arrow's impact, from 700 to 200 milliseconds and from 1,200 to 700, and compared them with rest, bow down and eyes on the target. Even in the earlier window, between 1.2 and 0.7 seconds before impact, theta and beta are lower and alpha higher than at rest, in all three sessions: the difference from rest does not appear only in the last half second. The drop in beta involves almost the whole cortex and the drop in theta slightly less in this window, while the rise in alpha is less widespread on the first two days. Three things limit what can be said. The comparison is with rest rather than with another phase of the shot, so the difference also contains the drawn bow and the effort of holding it; no window reaches back beyond 1,200 milliseconds, so nobody knows when the state begins; and these are complete beginners who raise and draw the bow on command, not trained archers.claim:stato-mira-anticipo:revision:2026-07-29:2Wed, 29 Jul 2026 08:00:00 GMT https://matteocampagna.com/en/registry/mind/brain-activity-before-impactclaim:stato-mira-anticipo:new_claim:2026-06-13:riportatoSat, 13 Jun 2026 08:00:00 GMT
