Electric fields generated by neural activity aren't just a side effect. They actively expand the dimensionality of population activity and improve decoding. Ephaptic coupling improves the neural population code doi.org/10.64898/202... #neuroscience

🚨 📝 New preprint: Ephaptic coupling improves the neural population code Ephaptic coupling has always been a point of debate between the neural-code and the field-activity crowds. We find a network's own field improves its code, but the same field imposed from outside wrecks it. 👇(1/3)

Our paper is out in JNeuro! We introduced KIASORT, a geometry-free spike sorting method that tracks each neuron’s own drift instead of assuming the whole probe moves as one block. In benchmarks with messy, neuron-specific drift it beat Kilosort4 www.jneurosci.org/content/46/2... Also: Kiasort.com
