21-12-01 进入寒冷的冬季，很多人都有早上起床困难的问题。不管闹钟响了几次，总是感觉睡不醒，被窝里面好暖好舒服，哪里都不想伸出来。 这是咋回事儿？难道一到冬天，人也会像有些动物一样需要冬眠吗？今天我们就从科学角度详细说说，为什么冬天起床更困难。 A study conducted...

16-01-31 Researchers have successfully demonstrated how it is possible to interface graphene - a two-dimensional form of carbon - with neurons, or nerve cells, while maintaining the integrity of these vital cells. The work may be used to build graphene-based...

15-08-07 Two labs in China have independently succeeded in transforming skin cells into neurons using only a cocktail of chemicals, with one group using human cells from healthy individuals and Alzheimer's patients, and the other group using cells from mice....

14-09-03 When we learn, we associate a sensory experience either with other stimuli or with a certain type of behaviour. The neurons in the cerebral cortex that transmit the information modify the synaptic connections that they have with the other neurons. A...

13-10-28 Dendrites（树突） , the branch-like projections of neurons, were once thought to be passive wiring in the brain. But now researchers at the University of North Carolina at Chapel Hill have shown that these dendrites do more than relay information fr...

13-10-20 Schizophrenia patients usually suffer from a breakdown of organized thought, often accompanied by delusions（妄想） or hallucinations（幻觉） . For the first time, MIT neuroscientists have observed the neural activity that appears to produce this di...

12-11-15 The human nose has millions of olfactory（嗅觉的） neurons grouped into hundreds of different neuron types. Each of these neuron types expresses only one odorant receptor, and all neurons expressing the same odorant receptor plug into one region in...

11-11-16 For decades, scientists have dreamed of building computer systems that could replicate（复制，折叠） the human brain's talent for learning new tasks. MIT researchers have now taken a major step toward that goal by designing a computer chip that mimi...

11-06-23 Two studies featuring research from Weill Cornell Medical College have uncovered surprising details about the complex process that leads to the flow of neurotransmitters（神经传导物质） between brain neurons -- a dance of chemical messages so delica...

11-05-29 The New York Stem Cell Foundation (NYSCF) a non-profit organization dedicated to advancing cures for major diseases through stem cell research today applauded（赞同，称赞） the announcement by Stanford University scientists, led by NYSCF Robertson I...
