Axon-like active signal transmission.

ABSTRACT: Any electrical signal propagating in a metallic conductor loses amplitude due to the natural resistance of the metal. Compensating for such losses presently requires repeatedly breaking the conductor and interposing amplifiers that consume and regenerate the signal. This century-old primitive severely constrains the design and performance of modern interconnect-dense chips¹. Here we present a fundamentally different primitive based on semi-stable edge of chaos (EOC)^2,3, a long-theorized but experimentally elusive regime that underlies active (self-amplifying) transmission in biological axons^4,5. By electrically accessing the spin crossover in LaCoO₃, we isolate semi-stable EOC, characterized by small-signal negative resistance and amplification o
