OPTICAL PROPERTIES OF HUMAN BRAIN

Abstract

Abstract— Optical properties of the human brain in the wave‐length region from blue to near infrared are presented. There are significant variations in the optical penetration depth from the neonatal and to the adult brain. Typical values for the penetration depth in the adult brain are: 0.5 mm for blue/green, 1.5 mm for red and 3.5 mm for near infrared. The values for the neonatal brain are typically 2–3 times larger.
