AB  - imulators have been developed, each specialized on one or few spatial and temporal scales [1]. But thereliable and reproducible simulation of such complex systems as the brain is a very demanding challenge.Thus, the Computational Neuroscience community concentrated on a few reliable and widely used simula-tion tools in recent years. This concentration was not least the result of a series of large-scale EU fundedprojects, such as FACETS, BrainScaleS and the recently announced Human Brain Project.From its humble beginnings as a PhD-student project 20 years ago, the Neural Simulation Tool NEST [2]saw its first incarnation as the SYNOD simulator in 1995 [3]. By tightly coupling software development withcomputational neuroscience research [4], simulator technology evolved steadily, facilitating new scientificinsight at almost every step. Some key examples were parallelization [5,6], exact integration of modelequations [7], precise spike times in a time-driven simulator [8,9], spike-timing dependent [10] and neuro-modulated plasticity [11], and a Topology module for spatially structured networks [12]. Streamlined datastructures [13] allow NEST to efficiently exploit the capabilities of some of the largest computers on Earth forsimulations on the brain scale [14]. Systematic quality assurance through testsuites [15] and continuousintegration technology [16] ensure simulator reliability. With a user-friendly Python-based interface [17],integration with PyNN [18] for simulator-independent scripting and MUSIC support [19] for integrated multi-scale simulation, NEST is a powerful simulation tool for brain-scale simulations today.
