Brain tissue penetration and temperature. A Diagram of the NIR treatment device with light emitting diode arrays fixed to an aluminum heat sink. B Diagram of the surgical implantation of photodiode and thermocouple. C NIR penetration measurements, measured with an implanted photodiode at 4 cm performed through the swine head, measured at the hippocampus compared to unimpeded measured at 4 cm distance from the LEDs (i.e., without tissue between the LED and the power meter. D Temperature was measured during NIR treatment with thermocouples placed in the skin (0.2 cm), surgically implanted in the surface of the cortex (1.5 cm), and the hippocampus (4 cm). Data represented as Mean + SD
