(120223) -- HANGZHOU, Feb. 23, 2012 (Xinhua) -- A monkey named Jianhui prompts a mechanical arm to make a hand gesture via brain signals in a lab in Hangzhou, capital of east China's Zhejiang Province, Feb. 23, 2012. A tiny sensor implanted in Jianhui's brain is allowing the animal to use its mind to prompt a mechanical arm to reach and grab food and drinks, scientists with east China's Zhejiang University announced Monday afternoon. The technology, Brain-Machine Interface (BMI), is a real blessing for people with paralyzing conditions, according to Zheng Xiaoxiang, the professor leading the research group.
