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 ...
To enjoy the scent of morning coffee and freshly baked cookies or to perceive the warning smell of something burning, the brain needs two types of cells, neurons and astrocytes, to work closely with each other. Research has ...
