Transneural matrix
From Memory Alpha, the free Star Trek reference
A transneural matrix is the central component of a Borg vinculum, responsible for producing the neural interlink frequency that interconnects all Borg drones.
In 2375, the crew of the USS Voyager deactivated a vinculum infected with Species 6339's synthetic pathogen by targeting its transneural matrix with a dampening field. (VOY: "Infinite Regress")
