Astrocytes, previously thought of as helper cells for neurons, have recently been shown to send signals themselves. The signals are chemical not electrical and astrocytes send them to neurons, vascular cells and other ...

Growing evidence suggests that there may be a link between diabetes and Alzheimer's disease, but the physiological mechanisms by which diabetes impacts brain function and cognition are not fully understood. In a new study ...

Astrocytes are a type of glial cell in the central nervous system that clear excess neurotransmitters, promote the formation of synapses (i.e., connections between neurons), and perform other functions. The development of ...
New research by scientists at UC San Francisco shows that one of the brain's fundamental self-protection mechanisms depends on coordinated, finely calibrated teamwork among neurons and non-neural cells knows as glial cells, ...

Synapses are small gaps between neurons through which signals are transmitted. This transmission of signals is what allows neurons to communicate and ultimately produce complex internal processes, such as thoughts and feelings, ...
Cells that normally nourish healthy brain cells called neurons release toxic fatty acids after neurons are damaged, a new study in rodents shows. This phenomenon is likely the driving factor behind most, if not all, diseases ...
