%X Recent experimental evidence suggests an active roles of astrocytes in a number of brain functions and demon-strates coordinated neuronal and astrocytic activity in vivo [1]. In the cortex, astrocytes form non-overlappingdomains, each containing several hundreds of neurons and ~100,000 synapses [2]. Astrocytic processes arein close contact with synaptic terminals and affect synaptic transmission, plasticity, and neuronal excitability[3, 4]. Understanding the role of astrocytic mechanisms in brain functions and dysfunctions requires open-access tools for model implementation, simulation, and analysis. In the past decade, hundreds of new modelswith some form of neuron-astrocyte interaction dynamics have been proposed. However, their implementa-tion is rarely shared and not sufficiently documented to reproduce the findings [4, 5]. We developed a newmodule in the NEST simulator that allows efficient implementation and simulation of large neuron-astrocytepopulations. This includes an astrocyte model with internal calcium dynamics, a synapse model to commu-nicate between astrocytes and postsynaptic neurons, and user-friendly and efficient high-level connectivityfunctions, which allow probabilistic or deterministic pairing of neurons and astrocytes. This new module willimprove the convenience, reliability, and reproducibility of computational studies involving neuron-astrocyteinteractions.
