🧠 New paper by Pachitariu … @computingnature: spontaneous brainwide activity in mice shows macroscopic coordination that resembles linear dynamics driven by a critically normalized random symmetric matrix.
#Cortical and brainwide recordings showed power-law variance spectra, slow global activity modes, and little rotational structure, unlike #CA1, which looked closer to an efficient, less correlated code.

🧠 Interesting new work on #cortical #PopulationCoding: Revah, Wolf, Gutnick & Neef show that the #encoding performance of cortical #neurons is not determined by single-cell properties alone, but by a combination of #dendrite size, #synaptic noise statistics, ion channels, and population size.

🧠 New preprint by Garcia-Garcia et al.: The authors show that cerebellar #GranuleCells do not simply expand #cortical activity into a high-dimensional code. Instead, they preserve low-dimensional cortical #manifold geometry while reorienting it across contexts. This rotation separates similar tasks, reduces interference, and supports flexible dual-task learning.

🧠 New study by Lempel et al. (2025): Visual experience after eye opening aligns #feedforward inputs (L4) and #RecurrentNetworks (L2/3) in mouse #VisualCortex. This improved alignment, together with enhanced orientation discrimination, creates coherent, reliable sensory codes, revealing how experience shapes stable #cortical representations:

📚 New preprint by Song et al.: Geometry of #NeuralDynamics along the #cortical #attractor landscape reflects changes in attention. They show that while attractor positions are determined by cortical organization, the geometry of neural dynamics on the landscape changes systematically with attentional states and contexts.
