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.
