Topographic anova
WebAug 17, 2024 · The statistics of GMD were validated by a topographic ANOVA with 5,000 permutations (P < 0.05). Notably, GMD is independent of field strength and a significant GMD is indicative for different neural generators across 6 dimotif lattice conditions. Significant results of GMD were corrected by a duration threshold (20 ms). WebJun 12, 2010 · Finally, a topographic ANOVA (TANOVA, Kondakor et al. 1995; see also Murray et al. 2008) was performed between conditions on the maps computed from the N400 peak effect in individual difference waves to test if these peak maps differed between tasks in terms of their field configurations (i.e. topographical organization).
