“…(The first presentation of the images we obtained through optical topography was made in 1994. 22 Chance also reported phased-array optical imaging of phantoms in 1996. 23 ) In the next section, we describe the concept of optical topography and explain what made it possible to obtain NIRS functional images.…”

“…These topograms are very similar to those we obtained in 1994 where we used optical switching and could not obtain real-time images. 21,22 The neuro navigator, which was invented by our collaborator, Watanabe, 49 was used to determine the exact position of the central sulcus since the motor area on the frontal cortex and the somatosensory area on the parietal cortex are situated across the central sulcus.…”

Near-infrared spectroscopy is discussed from the viewpoint of human higher-order brain function analysis. Pioneering work in this field is reviewed; then we describe our concept of noninvasive trans-cranial dynamic optical topography and its instrumentation. Also, the validity of its functional images is assessed from both physical and physiological viewpoints. After confirming the validity of this method, we have applied it to a wide variety of fields such as clinical medicine, cognitive science, and linguistics in collaboration with researchers at several other institutes. Further application possibilities and the future of trans-cranial dynamic optical topography are also discussed. © 1999 Society of Photo-Optical Instrumentation Engineers.
