The idea of a robot that can learn and function on its own, without the need for any human help, might sound like the plot to the latest science fiction blockbuster.

But scientists have got one step closer to making this a reality with the creation of the first artificial brain connection that can learn autonomously.

The groundbreaking study represents a big step toward intelligent machines that learn without the need for human input.

A team of international researchers, led by scientists at the French National Centre for Scientific Research (CNRS) based in Paris, created the artificial connection (synapse).

The synapse changes its composition based on which 'brain signals' are fired.

When under heavy use, it adapted to drop its electrical resistance and make the signal pathway quicker and more efficient.

This, the researchers said, could one day build artificial intelligence that learns like the human brain.
