Neural processor
A neural processor was a device implanted in the nervous system of every Borg drone containing a record of all the information received from the Collective.

After the  traveled back in time from 2373 to 2063, Captain Jean-Luc Picard removed the neural processor implanted in the newly-assimilated Ensign Lynch, located in the abdomen. Attaching it to a tricorder, Picard was able to access the processor and discovered the Borg's plot to transform the Enterprises deflector dish into an interplexing beacon with which to establish a link with the Borg living in the 21st century.

Later in 2373, in the Delta Quadrant, a group of former Borg drones were able to activate their processors by using a portable neural transponder, re-linking their brain patterns. This allowed them to generate a neuro-electric field which, combined with a small neural transceiver attached to the base of the skull, was able to heal serious injuries sustained by Commander Chakotay, first officer of the , upon being fired upon by a particle weapon.
