With each passing year, the boundary between man and machine gets slimmer. Bionic ears have become commonplace, motorized prosthetics allow wounded soldiers to care for themselves, and electronic eyes are just over the horizon.

Neuroscientists have almost jacked rodents into the matrix: They have used electrodes to read signals from individual mouse brain cells as the critters wandered through a virtual maze. Monkeys can feed themselves with robot arms wired directly into their brains. Here are ten clips of inventions that unite nerves with electronic circuits.
