The gel packs formed the basis of the bio-neural circuitry, which was essentially an organic computer system. The packs contained neural fibers surrounded in a blue gel with metallic interfaces on the top and bottom. They helped store more information and operated at faster speeds than isolinear circuitry. The USS Voyager was one of the first starships equipped with the technology. (VOY: "Caretaker") Gel packs could not be replicated. (VOY: "Learning Curve") Voyager stored their spare gel packs in engineering locker Gamma 5. (VOY: "Renaissance Man")
