Comparative analysis of four reaction-diffusion simulation tools for astroglial geometries

Summary

Researchers systematically compared MCell, STEPS, NeuroRD, and NEURON by implementing equivalent calcium diffusion and calcium-calmodulin reaction-diffusion models across simplified and realistic astroglial geometries. All tools produced consistent results, but fine-scale branchlet morphology from human astrocytes and mouse Bergmann glia led to distinct calcium signaling, highlighting the need for accurate geometry representation in simulations.
