The fNIRS sensor, designed to image the PFC of adult humans, covers the forehead. The fNIRS sensor consists of reusable flexible circuit board that carries the near-infrared light sources and detectors, a replaceable cushioning material, and a disposable single-use medical-grade adhesive tape that serves to attach the sensor to the participant’s forehead. The flexible sensor, developed in the Drexel Biomedical Engineering laboratory, consists of four LED light sources and 10 detectors, which cover the forehead using 16 voxels with a source-detector separation of 2.5 cm. The 16-channel sensor (see ) has a temporal resolution of 500 ms per scan with 2.5 cm source-detector separation allowing for approximately 1–1.25 cm penetration depth, which has been used to detect hemodynamic changes in response to cognitive challenges and reported in previous studies ( –). The light sources (manufactured by Epitex Inc., Kyoto, Japan; type L4X730/4X805/4X850-40Q96-I) contain three built-in LEDs having peak wavelengths at 730, 805, and 850 nm, with an overall outer diameter of 9.2 ± 0.2 mm. The photodetectors (manufactured by Burr-Brown, Tucson, AZ; type OPT101) are monolithic photodiodes with a single-supply transimpedance amplifier. Communication between the data analysis computer and the task presentation computer is established via a serial port connection to time lock fNIR measurement to computer-generated task events (see ).
