Star Trek: 10 Secrets Of USS Voyager You Need To Know

One of the more novel technologies incorporated into the design of the USS Voyager was bio-neural circuitry, an organic computer system built to mimic fluid organic thought rather than rigid artificial computing. In essence, Voyager's bio-neural gel packs allowed the ship's computer to rationalize and make educated guesses where conventional computers would fail.

A side effect of this new, biological computer system, though, was that the bio-neural gel packs were susceptible to the same kind of diseases and maladies as the human crew. In the episode "Macrocosm", the gel packs came down with a case of macrovirus, in "One", Voyager's computer system was afflicted with radiation poisoning from a Mutara-class nebula, and, in "Learning Curve", the bio-neural gel packs were infected with bacteria from Neelix's cheese which could only be purged from the system by heating the ship and giving Voyager a fever to combat the illness.
