Cranial Implant
A device that is installed into the brain.
Cardassian Cranial Implant
Highly classified Cardassian biotechnological device used by the Obsidian Order. The implants, which were placed into the skulls of the order's operatives, were designed to stimulate the pleasure centers of the brain. This would release large quantities of endorphins, making the operative impervious to pain in the event the operative were tortured by an enemy.
Garak created a control for his implant and used it to relieve the pain of being exiled to Deep Space 9. After continuous use over a two-year period, his body became dependent on the higher level of endorphins, so that when the implant malfunctioned in late 2370, it nearly killed him. In particular, the malfuctioning of the implant damaged his leukocytes (a type of white blood cell) and caused a build up of toxins in his lymphatic system. Doctor Julian Bashir was able to synthesize Cardassian-compatible leukocytes to replace Garak's damaged ones after receiving information on Cardassian biochemistry with assistance from Enabran Tain, who had been the head of the Obsidian Order at the time Garak received his implant.

Borg Cranial Implant
In 2374, Captain Kathryn Janeway accessed Seven of Nine's cranial implant with a microfilament to activate her Borg bioelectric field, enabling her to escape a cell on the USS Dauntless. (VOY: "Hope and Fear")
One of the Borg drone's cranial implants was an interplexing beacon. In 2375, Seven of Nine received a set of phase corrections through this cranial implant during USS Voyager's quantum slipstream flight, which collapsed the slipstream and saved Voyager from destruction. The message had been sent by a future Harry Kim, from an alternate timeline. (VOY: "Timeless")
