The medulla is the first part that I would prioritize because the medulla is a part of the brainstem which regulates the cardiac, respiratory, and nervous system. It has connections to the central and peripheral nervous systems. It also contains 10 of the 12 cranial nerves. The medulla oblongata specifically relays information from the spinal cord to the brain. Any injury to the medulla will cause balance problems, vision problems, loss of pain and temperature sensation, and movement problems. 

The frontal lobe has the premotor and motor cortices which is important in the movement of an individual. Aside from the motor functions it holds, it is also responsible for decision making, problem solving, and planning. 

Although my quality of life would be diminished as I would have deficiencies and disabilities with the other aspects of being a human being such as emotions, memory, and so on, I would still have my autonomic functions intact, and I would somehow still be capable of thinking and moving.
