From: Activity of frontal pole cortex reflecting hedonic tone of food and drink: fNIRS study in humans
Experimental procedure. (A) Locations of optodes and channels. Red circle, emitter; blue circle, detector; square, channel with number, Fpz, a point defined in accordance with the International 10/20 system used in electroencephalography. The distance between emitters and detectors was set at 3 cm. The left side of the figure shows the cortical location of channels on a rendered brain. (B) Experimental design with a sample recording. Red trace, oxyHb level; blue trace, deoxyHb level; green trace, totalHb level.
