Fig. 4. Individual variability of LI of the temporal cortices: symmetrical or right-lateralized activation was observed in 22 of 27 subjects (81.4%) under the rSEN-SND contrast in the temporal cortices. Although 9 of 27 subjects (33.3%) showed symmetrical or right-lateralized activation under the SEN-SND contrast in the temporal cortices, all subjects showed left hemisphere dominance under the SEN-rSEN contrast. *, P < .05; **, P < .001.
