Local RNA Editing in Squid Giant Axon (IMAGE) Marine Biological Laboratory Caption Top, schematic of squid anatomy showing the location of the "giant axon," an unusually large neural projection that partly controls the squid's jet propulsion system, used for very fast movement, attacks and escapes. Below, schematic of a neuron, showing the location of the nucleus where all RNA editing was previously thought to occur, and the axon, where local RNA editing was identified in squid.
