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...
You can grow new brain cells. Here's how: 1. The growth of new brain cells can help with bad mood and mental diseases such as depression. 2. Learning and doing sports that can bring blood to your brain can increase new growing brain cells. 3. Stress, lack of sleep and growing older...

How many times do you think families see each other after their kids get married? KI-JUNG (scoffs) Crazy fuck. KI-WOO You hear about people hiring actors to stand in for their parents at weddings. We’ll do the same thing. A lot of TV extras do that kind of work. Ki-Woo ...
When a person thinks, speaks, eats, walks, or just sits comfortably with all bodily systems functioning normally, the billions of cells that make up the brain and the rest of the nervous system are hard at work. The brain is an information-processing organ, and the brain cells that ...
The study published on Monday in the Proceedings of the National Academy of Sciences, outlined how a protein called CPEB3 primes neurons to store memories that stand the test of time in mouse cells. The findings offered a never-before-seen view into one of the brain's most universal and ...
根据文章第五段The scientists then conducted another test in the opposite order:They implanted human brain cells which could respond to blue light,and then trained the rats to expect a "reward" of water from a pipe when blue light shone on the neurons via a cable in the animals...
Ca2+ is a ubiquitous second messenger in many cell types, underlying several physiological processes such as excitability, contractility, exocytosis, and differentiation [7]. However, there is an emerging role of Ca2+ and related proteins in cell motility, growth, migration, proliferation and tumor ...
Mitochondria play an essential role in maintaining cellular health. When damaged, they are removed through a recycling process called mitophagy, which is crucial for the function of long-lived cells, especially in the brain. Impaired mitophagy has been strongly associated with neurodegenerative disorders...
in the journalCell Stem Cell, showed that thesebrain cellsare characterized by markers of stress as well as changes in which thecellsbecome less specialized. Interestingly, many of the alterations seen in these cells are similar to what's been observed in cancer cells—another disease linked to...
