Effects of wavelength on transcranial laser stimulation: a Monte Carlo simulation study based on standard brain model (Conference Presentation)

Paper Abstract

Transcranial laser stimulation (TLS) is a neural type of photobiomodulation that has been shown beneficial effects on neurons. However, previous research in this field has used multiple wavelengths in the red to near-infrared range. It remains unclear which wavelength is optimal to stimulate the brain. In this study, Monte Carlo simulations are conducted to exposit the efficiencies of three representative wavelengths (660 nm, 810 nm and 1064 nm) in delivering photon energy into the brain. The results indicate that 1064 nm is the optimal, benefiting from its reduced tissue scattering.
