You can find below the scripts developed in my research projects.
IP3R-dependant Ca2+ signaling in fine astrocytic processes
- ODEs: deterministic, well-mixed implementation of the model with XPPAUT software
- Gillespie: stochastic, well-mixed implementation of the model in Python
- Particle-based: stochastic, spatial, in 2 spatial dimensions, implemented in C language
- Voxel-based: stochastic, spatial, in 3 spatial dimensions, implented in python, using STEPS software
Simulations in idealistic 3D geometries of fine processes based on recent super-resolution microscopy data
Simulations published in Denizot et al., bioRxiv, 2021. Reaction-diffusion simulations were performed in 3D meshes that were designed from the latest data available from super-resolution microscopy on astrocytes from Arizono et al., Nature Communications, 2020. The high spatial resolution of this model allows to propose plausible mechanisms by which astrocyte morphology at the nanoscale, notably shaft width, can influence local calcium dynamics and thus affect specialized neuron-astrocyte communication. The simulation code and 3D meshes designed in this study can be downloaded here.
Analysis of geometrical properties of 3D meshes
Generation of realistic perisynaptic astrocytic processes meshes with various endoplasmic reticulum distributions and constant shape
Scripts implemented in python to generate 3D meshes of perisynaptic astrocytic processes with various ER distributions and constant shape using Blender software. The code and resulting meshes are available here and were used in Denizot et al., bioRxiv, 2022.
