39 healthy volunteers received 60 J/cm^2 of 850 nm infrared LED transcranially. They experienced improved attentional performance in the Go/No task.

In a 2017 study, 31 healthy volunteers received 903 nm LED LumiWave light transcranially. They experienced improved reaction time in the qEEG event-related response test.

In a 2015 study, 25 healthy elderly women received 627 nm transcranially at four sites, two times per week for four weeks. They experienced increased cerebral artery velocity at both systolic and idastolic measurements.

Gen Therapeutics, LLC (Dallas, TX, USA) 1064 nm 250 mW/cm2, 60 J/cm2, 8 min, one irradiation session, CW Transcranially;
2 sites, lower and upper portion of right lateral forehead at EEG map sites: FP2, F4, and F8 sites Improved prefrontal rule-based learning; no significant effects on information-integration learning

In a 2016 study 12 healthy volunteers were irradiated with a 1064 nnm laser light dose of 13.75 J/cm^2 per minute for 10 minutes. Light shone on the center forehead and right side. Treated subjects exhibited higher oxygen concentration in hemoglobin across the two hemispheres. Oxygenation increased during treatment and continued at least 6 minutes … Read more
