Abstract

The evolutionary pattern of different astrocyte types across animal species remains unresolved. In a recent study, Falcone and colleagues revealed that varicose projection astrocytes, a rare form of astrocyte characterized by long varicosities-containing processes, are exclusively found in hominoid brains while being absent from other primate brains.

Keywords: cortex cell type; evolution; glia; human; primates.
