Minding brains

Leading neurologist Wang Yongjun has made it his life's work to tackle cerebrovascular disease - a common killer in China - head on, Li Yingxue reports.

Wang Yongjun knows a lot of trivia about the human brain. "An adult's brain weighs around 1,500 grams, and 78 percent of it is water. There are about 100 billion nerve cells in an adult brain, and if they became excited all at once, the power could light up a 25-watt bulb," Wang tells the audience during the filming of the TV show, Voice.

The 57-year-old executive vice-president of Beijing Tiantan Hospital and the chief physician at its neurology department is also a postgraduate supervisor of Capital Medical University. He is well experienced in the diagnosis and treatment of cerebrovascular disease, including stroke prevention, first aid and acute-stage treatment.
