  1. New preprint/model: the Rosa-Margin Hypothesis. When the vCA1 safety buffer shrinks (<~5 mV), everyday network transients trigger involuntary replay of emotional engrams → SZ/MDD/PTSD trajectories.
    Falsifiable endpoints: MEG γ-burst ↓ ≥35%, HRV rMSSD +≥5 ms.

  2. 📚 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.

  3. 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.

  4. Sometimes, #chemical reactions do not solely run stationary in one direction, but they show #spatio-temporal #oscillations. At TU Wien, a transition to #chaotic behavior on the #nanometer scale has now been observed.

  5. Hi folks! Here is my #introductionpost. I am a #neuroscientist & #psychiatrist based in NYC. I started a lab at Columbia in 2021 focused on how #stress disrupts the #brain #circuits that govern social, cognitive & reward seeking #behavior. We use #electrophysiology & #optogenetics in freely moving mice to study how dynamic #neural activity, eg, #oscillations yield insight into #susceptibility #resilience #anhedonia & new treatments. I also post about #cooking. #twitterMigration #NeuroMastodons
