Today scientists are growing brain cells of animals in petri dishes and then putting electrodes into them and using the brain cells to do tasks based on stimuli and then move the electrical impulses into other electrodes. Scientists and researchers are also using human and chimpanzees in experiments where by the subject thinks a thought and is able to fire an electrode to more something else on a computer screen.
This is just the beginning and indeed these scientific endeavors will help people see who are blind via optic sensors. Allow people who are deaf to hear thru electro-mechanical devices and vibration sensors and even amputees move limbs wirelessly by thought alone. Very cool stuff and the medical implications are true miracles and marvels of science.
Although a brain transplant has not been done yet, eventually a person whose body is worn out may be able to hook themselves up to a machine which will regulate a steady
