Figure 3. fNIRS channels showing statistically significant activity for within-condition investigation (p<0.05) were mapped onto a standard head model with a thresholded t-statistics. Significantly active channels in A) SRC, and B) ORC .
For between-condition comparisons, paired sample student t-test revealed significant activations in channel 2 (t12=2.41, P=0.33); channel 7 (t12=2.35, P=0.37); channel 12 (t12=2.27, P=0.46); channel 20 (t12=2.66, P=0.24) (Fig. 4). These channels correspond to right BA 45 and 46; left BA 9, 10, 11, 45, and 46 (Mutlu et al., 2020). These channels are further explained in the Discussion section.
