Just how the human brain functions remains one of the greatest unsolved puzzles. To solve this mystery, brain-function imaging for visualization of brain functions has developed rapidly in recent years. In particular, in vivo optical imaging by functional near-infrared spectroscopy (fNIRS) has attracted attention as a technique that supports next-generation brain science. Utilizing its leading-edge science and technology, Shimadzu has developed the LABNIRS, thereby contributing to the still growing field of brain science.
