3.2. fNIRS Results
Channel-based one-sample student t-test revealed different activity
profiles for subject relative clause (Fig. 3A) and object relative
clause (Fig. 3B) conditions. In the SRC condition, a limited significant
hemodynamic activity was found in three channels (P<0.05).
These channels roughly correspond to Brodmann Area (BA) 9 in the middle
portions of the prefrontal cortex and the left frontopolar area (BA 10)
and DLPFC (BA 46). On the other hand, ORC revealed more widespread
hemodynamic activity across the prefrontal cortex (P<0.05) as
well as greater hemodynamic activity in the left prefrontal cortex
including DLPFC.
