Neural scan interface
A neural scan interface was a technology invented by Lieutenant Reginald Barclay while under the influence of a Cytherian probe in 2367.

After having his intelligence drastically increased by the probe, Barclay used the holodeck to create the necessary equipment, and tied his brain into the 's main computer core, instructing the computer on how to perform the procedure. This had the effect of integrating Barclay's thought processes into the Enterprise-D itself, essentially allowing him to act as the ship's computer. Utilizing this interface, Barclay generated a highly-charged graviton field from the warp nacelles, creating a powerful subspace distortion which transported the Enterprise-D 30,000 light years away, to the center of the galaxy. There, the crew encountered the Cytherians, who disconnected Barclay from the computer and returned his intelligence to normal. ()
