Brain networks in newborns and infants with and without sensorineural hearing loss: A functional near-infrared spectroscopy study

Figure 1 Overview of functional near-infrared spectroscopy channel positions and optode placement. A: Spatial arrangement of 63 channels on a head template with channel numbers ranging from 1 to 36; B: Layout of the functional near-infrared spectroscopy (fNIRS) sources and detectors, with the fNIRS source depicted in red and the detector shown in blue. Source 7 is positioned at the center of the layout design and corresponds to the frontal region of the brain, as indicated in A.
