The study abstract below finds that photobiomodulation therapy increases the speed of information processing and enhances brain function. Researchers are now celebrating more and more confirmatory evidence that photobiomodulation offers the opportunity to reverse dementia in many cases and is a viable therapy for persons diagnosed with Alzheimer’s.
Transcranial photobiomodulation-induced changes in human brain functional connectivity
Biomed Opt Express. 2020 Sep 22;11(10):5783-5799.
Transcranial photobiomodulation (tPBM) with near-infrared light on the human head has been shown to enhance human cognition. In this study, tPBM-induced effects on resting state brain networks were investigated using 111-channel functional near-infrared spectroscopy over the whole head. Measurements were collected with and without 8-minute tPBM in 19 adults. Functional connectivity (FC) and brain network metrics were quantified using Pearson’s correlation coefficients and graph theory analysis (GTA), respectively, for the periods of pre-, during, and post-tPBM. Our results revealed that tPBM (1) enhanced information processing speed and efficiency of the brain network, and (2) increased FC significantly in the frontal-parietal network, shedding light on a better understanding of tPBM effects on brain networks.
