Where Astrocytes Live in the Brain
A tour of astrocyte distribution — cortex, hippocampus, brainstem, and beyond.
Astrocytes populate every region of the central nervous system, but their density, morphology, and functional properties vary by region — a mapping neuroscience is still refining.
§ 1
Cortex and hippocampus
Gray-matter regions are populated by protoplasmic astrocytes occupying non-overlapping anatomical domains.198
§ 2
White matter
Fibrous astrocytes predominate in white matter tracts, where they interact closely with myelinated axons.
§ 3
Specialized regions
