Runtime Construction of Large-Scale Spiking Neuronal Network Models on GPU Devices

no code implementations16 Jun 2023 Bruno Golosio, Jose Villamar, Gianmarco Tiddia, Elena Pastorelli, Jonas Stapmanns, Viviana Fanti, Pier Stanislao Paolucci, Abigail Morrison, Johanna Senk

Simulation speed matters for neuroscientific research: this includes not only how quickly the simulated model time of a large-scale spiking neuronal network progresses, but also how long it takes to instantiate the network model in computer memory.

Connectivity Concepts in Neuronal Network Modeling

no code implementations6 Oct 2021 Johanna Senk, Birgit Kriener, Mikael Djurfeldt, Nicole Voges, Han-Jia Jiang, Lisa Schüttler, Gabriele Gramelsberger, Markus Diesmann, Hans E. Plesser, Sacha J. van Albada

We hope that the proposed standardizations will contribute to unambiguous descriptions and reproducible implementations of neuronal network connectivity in computational neuroscience.

Prominent characteristics of recurrent neuronal networks are robust against low synaptic weight resolution

no code implementations11 May 2021 Stefan Dasbach, Tom Tetzlaff, Markus Diesmann, Johanna Senk

For networks with sufficiently heterogeneous in-degrees, the firing statistics can be preserved even if all synaptic weights are replaced by the mean of the weight distribution.

Reconciliation of weak pairwise spike-train correlations and highly coherent local field potentials across space

1 code implementation25 May 2018 Johanna Senk, Espen Hagen, Sacha J. van Albada, Markus Diesmann

Based on model predictions of spiking activity and LFPs, we find that the upscaling procedure preserves the overall spiking statistics of the original model and reproduces asynchronous irregular spiking across populations and weak pairwise spike-train correlations in agreement with experimental data recorded in the sensory cortex.
