Can you have eyes in the back of your head ?

Researchers at Tufts University may have the answer following a bizarre experiment with tadpoles.

During the research, scientists removed the eyeballs from the tadpoles of African clawed frogs and then implanted them in to their tails. Using a special color-coded tank it was possible to determine that the new eyes were functioning correctly - the tadpoles were literally able to see out of their behinds. Even stranger, it turned out the eyes weren't connected up to the brain at all yet still appeared to be in full working order.

The research opens up the future possibility of performing transplants that don't require a direct connection to the brain. "There are many implications of this study, but the primary one from a medical standpoint is that we may not need to make specific connections to the brain when treating sensory disorders such as blindness," said study co-author Michael Levin.

"Get ready for custom eyeball transplants for people who absolutely must have eyes in the backs of their heads - or pretty much anywhere on their bodies."

Politicians have been talking out of their tails for many years! That's exactly what i was going to say.

Why did they transplant the Eyes onto the Tail, though? If they wanted to be altruistic and help the poor Tadpole see, they might at least have put them at the right end. The ppor thing won't know whether it's coming or going.

Politicians have been talking out of their tails for many years! Very true, and what they come out with is quite appropriate for the place it is exiting!

They don't address the most important question: What happens wheen the tadpole turns into a frog? Can it still see out the eye? Is the eye still on its back?

Could similar transplants be performed on vertebrates and higher level organisms in the future? Ok, so they have tried this out on tadpoles, I do not want to even think about how they will try this out on humans, but i would not be at all surprised if they are already trying it in some windowless lab somewhere. What could possibly the purpose of trying this out on other species if they have no intentions of trying it out on humans one day? Mutating animals is not mans right!

The guy was pretty clear: A primary goal in medicine is to one day be able to restore the function of damaged or missing sensory structures through the use of biological or artificial replacement components. There are many implications of this study, but the primary one from a medical standpoint is that we may not need to make specific connections to the brain when treating sensory disorders such as blindness. I.e. it may be possible to implant replacement eyeballs (and other sensory structures) into people with damage, without knowing exactly how to wire them up to the brain, because it'll fo... [More]

wow That's pretty awesome that they could see behind their tails but also pretty disturbing in the following sense & reasons.why would anyone in their right minds want their eyes in Their back of the head or their behind.also I am strongly against with science in messing around With nature.the only reasons I don't have no problem with science is if its finding natural ways to save endangered species or positive non harmful beneficial reasons behind them and purposes.but science is not to blame its the scientific community that lack morals,ethics and reason and a lock of respect of nature a...

Well, when it matures into a frog, it can see if its own ass is water tight.
