I don't know about earlier (don't see it mentioned), but as of DC 1.4005 that Brain teleports you out of the Bloodsucker Den, then spawns a Controller. Even after killing the controller, the brain will continue to teleport the player out of the room.

Edit: Nevermind, it's part of a quest for Sakharov.
