Fig. 3.

fNIRS channel configuration at the 1-, 5- and 18-month age points. Highlighted are channels contributing to the ROI's at each point as identified by cluster permutation analyses. At the 1-month age point (top panel), a significant ROI based on the Fam1_NIRS trials was found over bilateral middle temporal regions (yellow). At the 5-month age point (middle panel), a significant ROI spanning middle to posterior temporal regions was found for the Fam1_NIRS trials (orange) and Novelty trials (light green). At the 18-month age point (bottom panel) ROI's were found over middle to posterior temporal regions for the Fam1_NIRS (red) and Novelty (dark green) trials.
