Understanding brain injuries with astrocytesRSS Feed
Scientists in Sweden have found that common brain cells known as astrocytes affect the nerve signals that make our brains work, in a development that could help with the understanding and treatment of brain injuries.
Researchers from the University of Gothenburg have shown that the astrocytes play a previously unknown role in the process of signals being transmitted between the neruons (nerve cells).
It had been previously thought that these cells played a "housekeeping" role such as the regulation of blood flow between different areas of the brain.
My Andersson, a researcher from the university, said: "This means that astrocytes should be given more attention in future when looking for causes of diseases that affect signalling between neurons."
The team found that the astrocytes modulate the effectiveness of signalling between neurons by reducing the release of glutamate, a neurotransmitter.
Recently, scientists at Arizona State University tested a system of non-invasive ultrasound therapy that could be used to treat brain injury patients.
