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 becam...
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 ...

Whichever theory it may be studies find the cells have a poor grasp of longer interval. Time does seem to slow during an empty afternoon and race when the brain focuses on challenging work. Stimulants (兴奋剂) including caffeine tend to make people feel as if time is passing faster; complex...

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 ...
A trio of studies are investigating the role our brain’s immune cells play in the progression of Alzheimer’s disease. Researchers are revealing these cells can contribute to neurodegeneration, and how they may be harnessed to prevent neuron damage.
Scientists have known that a type of brain cell circuit helps regulate a variety of innate and learned behavior in animals, including theirtemperaturepreferences. What has been a mystery is whether or not this behavior stems from a specific set of neurons (brain cells) or overlapping sets. ...
Of course, many of these are beyond your control, like childhood events, but some are entirely within your control, such as diet, exercise, stress management, and emotional states. The last two factors are directly dependent on your thoughts. Your Biology Does Not Have to Be Your Destiny ...
You don't have to think about breathing because your body's autonomic nervous system controls it, as it does many other functions in your body. If you try to hold your breath, your body will override your action and force you to let out that breath and start breathing again. The respira...
