Threshold for reporting for all higher-level contrasts was p < 0.000001 and cluster p < 0.001 for FWE for humans and p < 0.001 and cluster p < 0.05 for FWE for dogs. All peaks ≥16 mm apart are reported.
aAt p < 0.001, these two peaks result from D > H as a single cluster's two main peaks. When checked with a stricter p < 0.0005 threshold, a left and a right cluster-corrected significant cluster is obtained, with the same peaks. Thus, in dogs, the main and the subpeak are reported but in humans, in the absence of single bilateral clusters, subpeaks are not reported.
