Acute Effects of Near Infrared Light Therapy on Brain State in Healthy Subjects as Quantified by qEEG Measures.

What the authors concluded

Change in reaction time significantly differed between treated and control, with a mean of 23.8 msec improvement compared with controls (p = 0.035). Amplitude increased an average of 0.81 μV in treatment versus 0.22 μV in controls and did not reach significance." "The data suggest that NIR light may have an acute effect on reaction time and amplitude in certain subject subsets. There were no adv
