In mouse #BarrelCortex, slow recurrent background fluctuations appear to compensate for the tiny dendrites of L4 spiny stellate #neurons, allowing even single #thalamocortical #spikes to be reliably represented at the population level with millisecond precision.

🧠 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 paper by Tafazoli et al. (2026): The authors show that the brain reuses the same lowdim #NeuralSubspaces across tasks. #Sensory features & #MotorActions are encoded in shared population #subspaces, & task switching occurs by flexibly engaging & transforming activity between these representations. Monkeys adapt by updating internal task beliefs & routing activity through the appropriate shared subspaces.

Thoughtful overview of how #SystemsNeuroscience approaches emotional states, from #PopulationCoding to representational limits. Featuring comments from Tatiana Engel, David Anderson, Juan Gallego @juangallego , and Vivek Jayaraman.
