Man has create machines that are a zillion times stronger (construction equipment), faster (rockets) and with greater recall and logic skills (computers) than man. Then next frontier will most likely be biological - genetics, DNA and the brain - and biologically integrating these machines with man. And here it is...NYTimes Reports: Two monkeys with tiny sensors in their brains have learned to control amechanical arm with just their thoughts, using it to reach for and grab food andeven to adjust for the size and stickiness of morsels when necessary.
The monkeys had their own arms gently restrained while they learned to
use the added one.
Then, just beneath the monkeys’ skulls, the scientists implanted a grid about the size of a large freckle. It sat on the motor cortex, over a patch of cells known to signal arm and hand movements. The grid held 100 tiny electrodes, each connecting to a single neuron, its wires running out of the brain and to a computer.
The computer was programmed to analyze the collective firing of these 100 motor neurons, translate that sum into an electronic command and send it instantaneously to the arm, which was mounted flush with the left shoulder.
Most astounding is the ability to capture the biological motor neurons fromthe brain and translate them into motor coordination.
