Abstract:

Inter-hemispheric interaction is an objective index of reflecting brain function on the physiological basis of corpus callosum connecting the two brain hemispheres. The degree of handedness can show participants’ levels of inter-hemispheric interaction and the stimuli of eye movement can for the moment facilitate participants’ levels of inter-hemispheric interaction. So, inter-hemispheric interaction could be used as an independent variable to investigate its effect on cognitive activities. The related researches indicate that inter-hemispheric interaction has a significant impact on such cognitive activities as cognitive control, memory and decision making.

Key words: inter-hemispheric interaction, handedness, eye movement stimuli, cognitive activities
