abstract = {Astrocytes,the most abundant glial type in the cortex,
interact with neighboring synapses,neurons and glia through
complex cellular machinery (Bazargani et al.,
2016).Astrocytes form mostly nonoverlapping microdomains,
and a single suchmicrodomain can be reached by several
hundreds of neurons and as many as~100,000 synapses (Zisis
et al., 2021). Experimental studies have
demonstratedcoordinated neuronal and astrocytic activity
invivo (Lines et al., 2020). Computational methods can help
to integratethe data on cellular mechanisms and structural
organization of the corticaltissue, and to explore how
neuron-astrocyte interactions modulatepopulation-level
activity. In the past two decades, the number of
publishedcomputational models that include some form of
neuron-astrocyte interaction hasbeen steadily increasing
(Manninen et al., 2018; Manninen, Aćimović etal., 2018).
The majority of the published models was implemented in
custom madecode that is often not publicly available.
Implementing these models in wellestablished open source
simulation tools improves reproducibility of theresults and
sharing of the models (Manninen et al., 2018; Manninen,
Acimovic etal., 2018). Two earlier efforts to develop open
source tools for simulation ofneuronal and glial networks
include Arachne (Aleksin et al., 2017), and animplementation
in the Brian simulator (Stimberg et al., 2019). We developed
a new solution for efficient simulationof large
heterogeneous populations of neurons and astrocytes
implemented as a module in theNEST simulator
(https://www.nest-simulator.org/). We first extended
theconcept of a synapse in NEST to include interaction
between three compartments,pre- and postsynaptic neurons and
the neighboring astrocytic compartment. Next,we developed
new method to establish efficiently interactions within a
largeheterogeneous cellular population of neurons and
astrocytes. Finally, we testedthe new tool by analyzing
spontaneous activity regimes in medium-size networkscomposed
of several hundreds of cells. In summary, we present a new
module for NEST simulator that supports reproducible, open
access and efficient development of computational models for
large heterogeneous populations of neurons and astrocytes.},
