The growing recognition of spatial compartmentalization of intracellular calcium signals in glial cells such as astrocytes, is regarded as a potential biophysical correlate for the many functions that those cells could fulfill. Nonetheless, we currently miss any understanding of the biophysical mechanisms underpinning such compartmentalization. We present work in progress on an in silico model of astrocytic calcium signaling that combines diffusion of calcium with reaction-diffusion of inositol 1,4,5-trisphosphate. Consideration of different elemental branching configurations allows identification by analytical and numerical approaches of a variety of constraints of cell’s anatomy for the emergence of spatially-confined calcium dynamics.
