A lacking detail is, for example, information on thedistribution of in- and outgoing connections, resulting in substantial differences in networkdynamics. For reproducible research, unambiguous network descriptions and correspondingalgorithmic implementations are necessary [1]. Here, we review simulation software (e.g., NEST[2]), specification languages (e.g., CSA [3]), and published network models made available by thecommunity in databases like ModelDB [4] and Open Source Brain [5]. We investigate the networkstructures computational neuroscientists use in their models and the terminology they use todescribe these models. From this, we derive a set of connectivity concepts providing modelers withguidelines to specify connectivity in a complete and concise way. Furthermore, this work aims toguide the comprehensive and efficient implementation of connection routines in simulationsoftware like NEST, thereby facilitating reproducible research on network models.$\qquad$References: $\qquad$1.
