Small-world brain functional network altered by watching 2D/3DTV

• Studying the difference between the visual fatigue caused by 3D and 2D video.
• Using fMRI imaging and small-world networks to investigate the brain mechanisms caused by watching 3DTV.
• Suggesting the visual fatigue caused by watching 3DTV is related to temporal lobe and occipital lobe.

With the development of display technology, the healthy problems caused by watching 2D/3DTV have received more and more attention. This paper utilized resting-state functional magnetic resonance imaging to study the changes of small-world brain network before and after one-hour 2D/3DTV watching, and explored the brain fatigue mechanism caused by watching 2D/3DTV. We conclude that one-hour watching of 2DTV will not increase the burden of brain. On the contrary, one-hour watching of 3DTV requires the brain to regulate the efficiency of brain areas, such as temporal lobe and occipital lobe, which may explain the fact that watching 3DTV can easier cause brain fatigue than watching 2DTV.
