Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

Transcranial Light Therapy involves non-invasive and invisible beams of light that increase energy metabolism in the brain. Transcranial light therapy has been found to promote brain metabolism. The purpose of the study is: To asses the change in cerebral blood flow induced by the Transcranial Continuous and Pulse Near-Infrared Light Therapy in healthy subjects. To correlate with cognitive performance the change in cerebral blood flow induced by the Transcranial Continuous and Pulse Near-Infrared Light Therapy in healthy subjects. To correlate with skin pigmentation the change in cerebral blood flow induced by the Transcranial Continuous and Pulse Near-Infrared Light Therapy in healthy subjects. To assess the safety and tolerability of the Transcranial Continuous and Pulse Near-Infrared Light Therapy in healthy subjects
