Currently searchers are getting more interests in evaluating the brain functions on writing and typing activities. In order to discover the different effects of writing and typing on the brain, we establish experiments to test the oxygen consumption level in three areas of brain. We chose the Near-Infrared Spectroscopy (NIRS) to monitor hemoglobin changes. Subjects are required to type and write in the same environments while NIRS is used to record the hemoglobin dynamics. We used SPSS program as a statistical method. Image fusion was also applied to illustrate data from NIRS. The results turn out that when subjects are writing, oxygen concentration inside the brain increase more than when that inside the brain when they are typing. The experimental results show the brain has to work harder to control writing activity. By another word, writing excites brain more than typing. This fundamental information extends our knowledge of understanding on the brain behavior.
