Abstract

In many researches of cognitive processes, the afferent (bottom-up) signal flows were mainly investigated. However, recent reserches showed an increasing number of evidence of the existence of the efferent (top-down) information flow. Studies on the efferent phase will be important to explicate the higher cognitive processes. To find out time course of brain activation areas is necessary for these studies. Recently in some studies on mental rotation tasks with visual shapes (hands), activation of other modality which implies top-down process is observed. To study on this process, we measured subjects' neuromagnetic fields during a mental rotation task about character. In consequence, we estimated dipoles in right visual area (at about 150msec), left superior temporal region (at about 300msec) and superior parietal region (at 400msec and later). We found activation of motor regions at 300msec and later. We estimate an information processing model of the mental rotation from these result.
