A brain cylinder is a cylindrical, medium sized machine used by the Mi-go to transport humans to Yuggoth. It contains a living human brain, vivisected from its host and preserved in nutrient fluid. The cylinder can be connected with various devices that provide the faculties of sight, hearing and speech to the brain, allowing it to observe and interact with its surroundings.
