Bio-neural circuitry was a technology which was incorporated into Bio-neural gel packs, which were first installed aboard Federation starships in the early 2370s. The circuitry was designed to supplement and eventually replace the isolinear circuitry, as bio-neural circuitry was shown to process information more efficiently, and speed up computer response time as a result. The Intrepid-class starships that entered service in 2370, was one of the first starship classes to be equipped with bio-neural circuitry.
Using this technology, a starship's main computer processor was capable of simultaneous access to 47 million data channels, of transluminal processing at 575 trillion calculations per nanosecond, and having operational temperature margins from 10 ° to 1790 ° Kelvin. The bio-neural circuitry sped up the computer's data functions and improved overall performance.
Vanguard[]
Starships assigned to Vanguard Command have all been equipped with bio-neural circuitry. Flagships belonging to the Invincible-class, Suzerain-class, and Dauntless-class are large enough to be equipped with both bio-neural circuitry and isolinear circuitry.
