Remote operated rats!!

Home automation, robotics and all kind of devices that can be controlled by means of a remote is now under the shelves of consideration because now it’s the age of controlling living things by a remote. Scientists have implanted rats with electrodes in brain with battery backpacks. These electrodes transmit pulses generated by a computer into the brain, thus they can be remotely controlled. These pulses are provided to specific locations in brain and are rewarded by stimulating a pleasure center in the brain, so that the rat moves as being commanded. The thing more off concern including the ethical issues is that what if it spreads to human beings?
