Abstract

We report on a time-resolved instrument for diffuse NIR-reflectance topography of the adult head. It consists of 4 detection channels and one laser source the output of which is sequentially directed to 9 positions. The instrument allows to measure distributions of times of flight of photons on a grid of 4×4 positions. First results will be presented of time-resolved monitoring of the motor cortex area during finger tapping.
