What is "brainship"

The concept brainship in science fiction literature refers to an interstellar starship that is created by inserting the disembodied brain and nervous system of a human being into a life-support system, and connecting it surgically to a series of computers via delicate synaptic connections (a brain-computer interface). The brain "feels" the ship (or any other connected peripherals) as part of its own body. Flying, taking off, landing, and controlling all the other features of the ship are as natural as moving, breathing and talking are to an ordinary human. Being wired into a computer speeds their reactions, but still allows their human brains to make intelligent decisions based on calculations.
