Paper Abstract

A NIRS imager is used as a real time monitor in psychological test to record the response in blood oxyhemoglobin state and blood flow of the frontal gyri of human subject. The imager has 9 lamps and 4 dual detector pairs and an area of 9*4 cm. In mental work and pattern recognition test, we recorded oxygen consumption and blood flow changes of the volunteer's frontal gyri. The psychological results showed that down part of the left frontal gyri has intensive relation with pattern recognition and has definite boundaries. However, the mental work involved more zones of frontal gyri and it may be a more complicated think model. The results also suggested that brain have an exquisite and complicated adjust ability. As a result, the oxygen supplement in excited area increased as the neuron excited.
