Brain implants could give us a 'sixth sense' by making us see infrared

It has been put to good use by comic book superheroes and by alien predators hell-bent on wiping out mankind, but soon humans could also be able to see infrared light. Scientists have used brain implants to give rats a'sixth-sense' that enables them to detect and react to the normally invisible light source. The research proves it is possible for the adult brain to adapt to new forms of input and opens up the possibility of enabling humans to gain an array of superhuman senses. Scientists have connected infrared sensors to the brains of rats using electrical implants to allow the rodents to detect the normally invisible light. They found the rats were able to spot infrared light and react to it by pressing a button beneath an infrared source to get food. Researchers say it may be possible to attach sensors for other forms of light such as ultraviolet, microwaves and even x-rays using brain implants.
