SSCx toy circuit with 6k neurons in SONATA format

This dataset contains a toy circuit model of the rat somatosensory cortex (SSCx) in SONATA format with 5,924 neurons and 568,717 synapses. The toy circuit represents all six layers of the shoulder regions (S1Sh) of the primary somatosensory cortex (S1), but built with a reduced neuron density of only 7% of its biological density.

Its intended use cases are testing, benchmarking, and tutorials of connectome manipulation and simulation experiments, such as the ones outlined under /examples in the Connectome-Manipulator software repository: https://github.com/BlueBrain/connectome-manipulator

Two circuit configs are provided:

• circuit_config.json ... Circuit with one nodes population "All" containing all neurons and one edges population "default" containing all synapses
• circuit_config__no_conn.json ... Circuit with one nodes population "All" containing all neurons but no edges population, i.e., no connectivity

ℹ️ For running network simulations, follow the simulation instructions of a larger model of SSCx in SONATA format released under DOI 10.5281/zenodo.7930275.
