A ‘mind-blowing’ discovery has been made about the way the human brain works.

A study of people born with one hand suggests that areas of the brain are organised by functions rather than individual body parts.

The finding could fundamentally change our understanding of how the brain works and therefore how we treat brain injuries.

WHAT THE STUDY FOUND

Scientists had previously thought that certain areas of the brain are associated with certain limbs.

So one area of the brain controlled the hands, while another controlled the legs, etc.

A new study recorded the brain activity of people with one hand.

It found that the area of the brain associated with the subjects’ missing hand was activated when they used different body parts such as the mouth, foot or arm.
