Neural parasite aliens attempted to infiltrate the Federation's Starfleet Command in 2364, by physically infiltrating high-ranking admirals within the organization. Perons who fell victim to infiltration included Admiral Gregory Quinn, Admiral Aaron, and Admiral Savar.
The neural parasite's mother create had infiltrated Dexter Remmick. The mother creature was destroyed by heavy phaser fire at the hand of Captain Jean-Luc Picard and Commander William Riker of the USS Enterprise-D, thereby also killing all other parasite infiltrators on Earth. (TNG: "Conspiracy")
