(8) Linear motion processing in the brain: A visual evoked potential study
¡¡¡¡12th European Conference on Eye Movements, p.PC6, 2003-8

In order to investigate linear processing in the brain, the authors recorded 19ch visual evoked potentials during the following oculomotor tasks. On a CRT screen, a white circle moves vertically (upward or downward) or horizontally (left or right) from each side of the screen (¡Èlinear¡É). The speeds of the circle were 0.43 pixel per msec (¡Ècontinuous¡É mode) and 0.25 pixel per msec (¡Èdiscrete¡É mode). Subjects were instructed to tract the moving circle with binocularity. In the control task (¡Ècontrol¡É), the circle moves randomly in space on the screen, and the subjects were requested to trace the stimulus. Single equivalent current dipole source localization (ECDL) was applied to the difference wave between ¡Èlinear¡É and ¡Ècontrol¡É tasks.
