WASHINGTON, Aug. 12 (Xinhua) -- The U.S. scientists have mapped a part of the molecular machinery that helps the brain maintain long-term memories, providing new targets against Alzheimer's disease characterized by memory loss. The study published on Monday in the Proceedings of the National ...
Of 100 billion nerve cells in the human brain, how many form after birth? For years, the official answer was "zero". Scientists thought people were born with all the neurons they'd ever have. But from 1980s, biologists overturned that doctrine, finding a reservoir of stem cells that beca...

C. By zapping the brain cells of mice with light, researchers are able to create, erase, or alter their memories, good or bad. D. Many fancy ideas in science fictions or movies that are based on them actually draw greatly upon scientific achievement. Questions 18-19 (Suggested completion t...
synapse is a junction where electrical signals from neurons are communicated to another cell. The neuron-neuron synapse is the mostly widely known and was the first to be discovered; however, neurons form synapses with other brain cells too. The synapse between the axon and OPC is one such...
people do not have many skills for cooking, mostly they only boil, steam and bake the food. By the way, western people are very good at making desert and chocolate. They can make very good cake and chocolate. They are very sweet but it’s sort of food which make you become fat ...

How to Activate Brain Cells Scientists used to think that your brain stopped growing new cells once you reached adulthood. Happily, current research shows that it isn’t true! As you get older, you can continue to grow new brain cells. Get regular aerobic(有氧的) exercise. Research shows ...
