Is Seeing Believing (BBC Horizon) (2010)

This episode asks the question "Is seeing believing?" And is a great watch!
Can seeing some illusions (rather than seeing through one) be inherent from birth, by studying the effects of illusions on babies we find answers to such questions. This episode delves into the ability of certain blind people to use "echo location", much in the same way as bats do, to then create an image in ones visual aspects of the brain. We are shown how what we see can literally change the way things sound, taste and even feel, with some VERY unique experiments!

Have you ever heard of synestesia? Well you will have by the time this episode is over… and wow, what an area to look into! Seeing sounds, tastes and even touch!

And then we are even shown how scientists in Germany are trying to unlock a totally new sense in man, being able to sense the earth's magnetic field!

I hope you all enjoy this as much as I did!

Broadcast on Mon, 18 Oct 2010, 21:00 on BBC Two

Horizon explores the strange and wonderful world of illusions - and reveals the tricks they play on our senses and why they fool us.

We show how easy it is to trick your sense of taste by changing the colours of food and drink, explain how what you see can change what you hear, and see just how unreliable our sense of colour can be.

But all this trickery has a serious purpose. It's helping scientists to create a new understanding of how our senses work - not as individual senses, but connected together.

It holds the intriguing possibility that one sense could be mapped into another. This is what happened to Daniel Kish, who lost his sight as a child. He is now able to create a vision of the world by clicking his tongue which allows him to echolocate like a bat.

And in a series of MRI scans, scientists are now looking to find out if Daniel's brain may have actually rewired itself enabling him to use sound to create a visual image of the world.
