5、le.actually taking hold of a ball).Any problems with mirror neurons may well result in problems with behavior. Much research suggests that people with social and behavioral problems have mirror neurons which are not fully functioning. However, it is not yet known exactly how these discoveries might

6、help find treatments for social disorders.Research into mirror neurons seems to provide us with ever more information concerning how humans behave and Interact(互动). Indeed, it may turn out to be the equivalent(相等物) for neuroscience of what Einstein s theory of relativity was for physics. And the nex

These colourful and sweet jewels from British Columbias fields are little powerhouses of nutritional protection.Of the common berries, strawberries

Cloning was regarded with extreme doubts when it was first developed

25、 but became widely accepted after the birth of Louise Brown, the first “testtube baby”. He said, “When my first frog experiments were done, an American reporter asked how long it would be before these things could be done in mammals or humans.
