Watch the fascinating behaviour of a mass-spring-damper system as it transitions from overdamped (where motion is slow and heavily resisted) to undamped (where it oscillates freely without energy loss). This animation beautifully demonstrates how varying levels of damping impact motion and energy dissipation in mechanical systems.

I recently played around with #RateModels using #NESTsimulator. Compared to #SNN, RM focus on average firing rates of #NeuronPopulations, simplifying analysis of large networks. They effectively capture collective dynamics like #oscillations and #synchronization, though they miss precise spike timing details. Thus, both approaches have their merits. Here is a brief overview:

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.

📚 New article by Lopes-dos-Santos, Brizee & Dupret: Spatio-temporal organization of network activity patterns in the #hippocampus. They use a low-dimensional embedding of #CA1–#DG #LFP in behaving mice to reveal layer-specific #GammaRhythms and distinct firing motifs aligned with hippocampal microcircuit architecture – offering a data-driven view of how #oscillations coordinate #InformationFlow across hippocampal layers.

A few days back, I posted some #AnimatedGifs of the exact solution for a large-amplitude undamped, unforced #Pendulum. I then thought to complete the study to include the case when it has been fed enough #energy to allow it just to undergo #FullRotations, rather than just #oscillations. Well, it turns out that it is “a bit more complicated than I first expected” but I finally managed it.

The brain processes sensory information via gamma #oscillations, while top-down control is mediated via alpha/beta; how do these interact? This study provides a mechanistic account of the integration of these separate streams of information flow in visual attention @PLOSBiology https://plos.io/4iksxM3

Quantum heat dynamics toggled by magnetic fields: Research team of @HZDR, #unibonn and #cnrs discovers unknown mechanism of #heat conduction which causes dramatically enhanced heat #oscillations in the #quantum material #ZrTe₅.
