Here is a direct follow-up on this, now showing how to implement #GapJunctions in a network of #spiking #neurons (#SNN) using the #NESTsimulator. We simulate a network of 500 inhibitory neurons with gap junctions and analyze the effects on #synchrony and #oscillations. The code is also available on GitHub. Feel free to modify and expand upon it 🤗

📝 New blog post: #GapJunctions (#ElectricalSynapses) enable direct electrical and chemical communication between #neurons, synchronizing activity and supporting rapid signal propagation. Their #modeling is crucial for understanding #NeuralNetworkDynamics, #oscillations, and #brain 🧠 function. Here is a brief summary including a small #PythonTutorial using the #NESTsimulator.

Gap junctions allow transfer of metabolites between germ cells and somatic cells to promote germ cell growth in the Drosophila ovary
Gap junctions allow transfer of small molecules between cells, but it is unclear if cells can use this process to promote cell growth. Here, the authors show that gap junctions allow the exchange of metabolites between germ cells and somatic cells to promote germline growth during Drosophila oogenesis.

Gap junctions in Turing-type periodic feather pattern formation
Gap junctions mediate direct exchanges of ions or small molecules between cells, enabling rapid long-distance communication. This study shows that inhibition of gap junction intercellular communication can stimulate new feather bud formation in specific topological positions in developing chick skin explants, which can be predicted with mathematical simulations of consecutive waves of Turing’s instabilities.
