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.

#gnuplot plots of the phase-delay oscillator's outputs.
In order to get #oscillations going, the #transient analysis includes the `UIC` directive which asks #Xyce to forgo the typical operating point calculation, and instead use the supplied initial values (see `.ic` line). The specific initial values used should be non-zero, it is simplest to set the battery terminal node (n0) to some non-zero value.
The #Xyce #simulation of the PDO is here: https://codeberg.org/rjp/diy-tm/src/commit/0b9b12dd28ad2b7ed67f2dd0c2df811469916dae/pdo/sim/osc.sp#
Great having Mark Schnitzer at today’s #iBehave lecture at the @dzne! Fascinating talk on cell-type specific #VoltageImaging 🧠⚡ of neural #spiking, #oscillations, #waves, and #MemoryDynamics. Showing that spike-resolution #imaging 🔬 in vivo is finally there 💪
Lissajous Figures – Nostalgia and Innovation
Where did the impulse to draw 3D Lissajous figures come originally? I was looking for a compact three-dimensional curved shape. It should be symmetrical enough to allow for "easy geometrical doubling" of some points. But it should be asymmetrical enough to look surprisingly different from different viewpoints! Finding uncommon ways of looking at 3D structures had been the idea behind my physics-based code art - and it should carry over to traditional drawings! Lissajous figures are built […]https://elkement.art/2025/09/24/lissajous-figures-nostalgia-and-innovation/
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.
