trending towards significancep = 0.059
For between layer comparison, we found two time points during the encoding and early delay period (10-12 s) where the superficial layer showed stronger WM load decoding than the deep layer, with this time period trending towards significance at a temporal cluster level ( p = 0.059, d cluster X̄ = 0.85, two-tailed permutation test; Fig. 3a , black hollow diamonds).
