The description of astrocytes as information processors is technical, not metaphorical. Astrocytes integrate calcium-encoded signals across their processes and produce outputs that shape neural network behavior.

§ 1

Local computation

Individual astrocyte processes can exhibit locally distinct calcium activity, suggesting some capacity for spatially resolved computation.181,180


§ 2

Networks of astrocytes

Astrocytes are coupled via gap junctions into networks that can propagate signals across brain regions.186
