Perhaps you should try some spelling variations:
brain mapping » brain applying, brain imaging, brain machine
mapping min » mapping eine, mapping many, mapping can
hua brain » human brain, a brain, hua ban
zhong zhi » zhang zhi, zhong tai
hong ghi » hong g, hong hai
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 min ((hong ghi) OR (zhong zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yi) or (tan yi)) hua brain mapping min ((hong ghi) OR (zhong zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan yi) or (tan yi)) hua brain mapping min ((hong ghi) OR (zhong zhi)) ;*.
