Mechanism that repairs brain after stroke discovered
A previously unknown mechanism through which the brain produces new nerve cells after a stroke has been discovered by researchers. A stroke is caused by a blood clot blocking a blood vessel in the brain, which leads to an interruption of blood flow and therefore a shortage of oxygen. Many nerve cells die, resulting in motor, sensory and cognitive problems. The researchers have shown that following an induced stroke in mice, support cells, so-called astrocytes, start to form nerve cells in the injured part of the brain.
