Claim 0:
1. A system comprising:
a light source;
a photodetector; and
electrical circuitry,
wherein the electrical circuitry
causes the light source to emit at least one pulsed light with which a user is illuminated,
causes the photodetector to detect internal scattering components included in at least one reflection pulsed light that returns from the user, the internal scattering components being diffused in a brain of the user,
causes the photodetector to detect surface reflection components included in the at least one reflection pulsed light, the surface reflection components being reflected by a surface of the user,
generates a first signal indicating an amount of change in brain blood flow of the user based on the internal scattering components, and
generates a second signal indicating an amount of change in facial blood flow of the user based on the surface reflection components.
