From: fNIRS can robustly measure brain activity during memory encoding and retrieval in healthy subjects
Group average HbO changes (µM) during recalling (red) and encoding (pink) averaged over (a) medial and superior frontal cortices for novel faces and (d) lateral middle, lateral superior and left inferior frontal cortices for same faces. HbO changes (µM) averaged over the ROI defined by the channels marked in red on the head (c and f). The scatter plot (b and e) shows the response averaged over 25 to 50 sec for each individual subject. Each subject is depicted as a different color-filled circle. The p-values are for the difference between recalling vs. encoding of (b) novel and (e) same faces over 25 to 50 sec.
