Figure 2

(A) The medial optode column of a 3 × 3 fNIRS optode patch was placed over the midsagital line and directly above the brow. Four three-channel regions (colored triangles) were identified a priori. The anterior edge of a 2 × 3 fNIRS optode patch as placed over the interauricular arc and directly above the T4 10/20 location.
