Do you know how Albert Einstein’s brain is different from the rest of ours? It contains more astrocytes in the left parietal region (region associated with mathematical thinking)!
Astrocytes are a type of glial cell (cells in the nervous system that do not produce impulses) that are found at synapses (gaps between two neurons through which signals pass). They provide nutrition to neurons, maintain ion concentration and help recycle neurotransmitters.
Although there is still a lot to learn about astrocytes, they must be important as they make up around half of all glial cells!
