Cerebral Cortex Conduit

The Cerebral Cortex Conduit is an experimental device developed on Vohl by the Wraith for the purpose of giving the Wraith new ways to prepare and consume the life force of other beings, as well as probing the minds of their prey.

The Cerebral Cortex Conduit probes a subject's brain for information, as well as causes hallucinations. While this happens, the device drains the subject's blood in small controlled amounts.

The Wraith used this device on Major John Sheppard in an attempt to learn the location of Earth.
