Ice patterns can look like neurons: the Silhouette Fallacy and ephaptic coupling
neurovium · x · 2026-10-05
Companion blog to a new arXiv paper by Nima Dehghani arguing that neurons generate surrounding electric fields that feed back on their own activity (ephaptic coupling). The "silhouette fallacy": ice-crystal patterns can mimic neuron morphology without the missing state variables, with lessons for dendritic computation and NeuroAI.
