Perhaps you should try some spelling variations:
brain machine » ai machine, man machine
brain mapping » brain applying, brain imaging, bic mapping
min zhong » min hong, tin hong, amin hong
zhong zhi » zhang zhi, hong ghi, zhong tai
yan yi » yang yi, yan zi, yin yi
tan yi » tang yi, tan li, tan ying
wang » wing, wan, lang

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan yi) OR (tan yi)) hua ((brain mapping) OR (brain machine)) min zhong zhi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yi) or (tan yi)) hua ((brain mapping) OR (brain machine)) min zhong zhi ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan yi) or (tan yi)) hua ((brain mapping) OR (brain machine)) min zhong zhi ;*.
