N2 - Although symmetry is known to be an important determinant of visual processing and an appreciation of visual symmetry has been studied in several electroencephalography (EEG) experiments, it remains not well clear the mechanism of visual symmetry processing. To investigate this, we measured the processing of symmetrical stimulus (diagonal) and asymmetrical stimulus (control) with two levels of intensity by measured visual evoked potential (VEP). Our results showed significant difference in P8, P4 and O2, the right hemisphere for symmetry processing. In addition, the activity of visual related cortex for diagonal was weaker than that for control during the period of (160-190 ms), whereas the relationship was inverse during the period of (220-280 ms) in all intensity. This work provides a new account of neural mechanisms involved in visual symmetry perception.
