Abstract
Using NIRS, we investigated brain activity in subjects searching for target characters in given text. Visual stimuli consisted of two different contrasts: positive and negative. Both stimuli were displayed for 30 sec on a cathode-ray tube (CRT: 21 inches). The subjects were instructed to watch a visual display on the CRT. This display included text without meaning. When target characters were detected, subjects were instructed to perform three tasks: (1) count the number of target characters by visual observation, (2) tap a button with the thumb and fingers of their left hand carefully and as fast as possible and (3) operate a mobile phone.
