Detailed mapping of 1.2 million brain cells has revealed that not all cell types age in the same way and that some – found in a specific ‘hot spot’ – are more sensitive to the aging process. It opens ...

The human brain contains nearly 86 billion neurons, constantly exchanging messages like an immense social media network, but neurons do not work alone – glial cells, neurotransmitters, receptors, and ...

Neurons are the cells in the brain responsible for sending messages to the rest of the body, and scientists have long thought that they are settled into one subtype once they develop from stem cells, ...

The brain's immune system is getting attention at the Society for Neuroscience in Chicago. A lot of research is now focused on the interaction of neurons, glial cells and other immune cells. There's a ...

A new study finds that mitochondria in our brain cells frequently fling their DNA into the cells' nucleus, where the mitochondrial DNA integrates into chromosomes, possibly causing harm. As direct ...

The question of whether adult brains grow new brain cells has been debated for more than 60 years. Known as "neurogenesis", this process has been observed in the brain of other adult animals, yet its ...

Anxiety disorders are some of the most common mental health conditions in America, affecting about one in five people nationwide. But much remains unknown about the roots of anxiety in the brain. Now, ...

Scientists have developed a 'molecular GPS' to guide immune cells into the brain and kill tumors without harming healthy tissue. Researchers have found a way to program immune cells to attack ...

In recent experiments, rat brain cells filled in for lost neurons in mouse brains, raising new possibilities for growing donor tissues across species. When you purchase through links on our site, we ...

Scientists have found a way to restore brain cells impaired by a rare and life-threatening genetic disorder called Timothy syndrome. "It's immensely exciting because we now have the tools," says Dr.
