Fig 2. Changes of the astrocytic surface to volume ratio (SVR) and the volume ratio of internal Ca2+ stores compared to the intracellular space (ratioER) for astrocytic compartments along the astrocytic process.

Fig 2

A small ratioER corresponds to astrocytic compartments close to the synapse (perisynaptic astrocytic processes (PAPs)) and a high ratioER corresponds to astrocytic regions at the soma.
