Some parts of our bodies bounce back from injury in fairly short order. The outer protective layer of the eye—called the cornea—can heal from minor scratches within a single day. The brain is not one ...

Resting brain stem cells hardly differ from normal astrocytes, which support the nerve cells in the brain. How can almost identical cells perform such different functions? The key lies in the ...

Brain stem gliomas very rare growths that begin in the glial cells of the brain stem. Doctors can diagnose brain stem glioma using neurological exams and scans. Treatment may involve chemotherapy, ...

Aging affects all of us and leads to cell and tissue loss of function, multiple diseases, and eventually death. And, even after decades of robust research and billions of dollars spent, there are only ...

When someone has a stroke—a leading worldwide cause of death and disability—time is of the essence. Almost nine out of 10 cases are ischemic strokes, caused by restricted blood flow in the brain, and ...

Clues to keeping the brain’s regenerative cells youthful and energetic into old age have emerged by applying CRISPR gene editing to mice 1. Age impedes the ability of the brain’s stem cells to churn ...

Like the seeds of a forest, a few cells in embryos eventually sprout into an ecosystem of brain cells. Neurons get the most recognition for their computing power. But a host of other cells provides ...

Some parts of the body can recover from injury fairly rapidly. The cornea, for example, can heal from minor scratches within a single day. The human brain, however, is not one of these fast-healing ...

Researchers have created model embryos from mouse stem cells that form a brain, a beating heart, and the foundations of all the other organs of the body -- a new avenue for recreating the first stages ...

Scientists who study the brain have long tried to unlock the neural mysteries of schizophrenia and bipolar disorder. They can be difficult to diagnose and even harder to treat. The scientists began ...
