Global perception depends on coherent work of bilateral visual cortices: Transcranial magnetic stimulation (TMS) studies被引量：2
《Science China(Life Sciences)》2007年第4期557-565,共9页ZHANG Xin1 & HAN ShiHui1,2 1 Department of Psychology, Peking University, Beijing 100871, China 2 Learning & Cognition Lab, Capital Normal University, Beijing 100875, China 
Supported by the National Natural Science Foundation of China (Grant Nos. 30630025, 30225026, and 30328016);the Ministry of Science and Technology of China (Grant No. 2002CCA01000)
Previous research suggests that the right and left hemispheres dominate global and local perception of hierarchical patterns, respectively. The current work examined whether global perception of hierarchi-cal stimuli ...

This work was supported by National Natural Science Foundation of China （Grant Nos. 30225026 ＆ 30328016）;the Ministry of Science and Technology of China （Grant No. 2002CCA01000）;the Beijing Key Laboratory.
Prior behavioral studies suggested that global perception of compound stimuli is modulated by the way the local elements are grouped into global structures. The current work examined whether dis- tinct neural mechanis...
