Medical science has developed the ability to map the human brain and determine which parts of the brain control which parts of the body.

This is commonly done using electrodes attached the skull, with the changes in electrical impulses being mapped by computer.

How long do you think it will be before those impulses can be transferred from one person to another, for example someone who is suffering from a brain injury?

The record of impulses created by a healthy brain could be uploaded to a robotic device in the not too distant future, couldn't they?

Surely, a similar process can be used as a Lie Detector mechanism, to replace the long and loudly criticised systems currently in use?

If the answer to my questions are all in the affirmative, how far are we really away from Artificial Intelligence?

Would really appreciate members opinions here, after all, it could be just around the corner.





It's not that I was born in Ireland,
It's the Ireland that was born in me.

Yes, the difficulty is understand what the impulses mean. I looked at it a little bit during uni. The signal is very complicated and noisy. We use correlation algorithms to attempt to make sense of them but the process is not reliable. Eg, EEGs from drowsy people look like such and such. The best data is obtained from electrodes implanted below the skull. Much more success has been obtained that way, however there aren't too many people who want brain surgery to implant some electrodes.

An experiment was performed last year, or maybe the year before where two mice, one in brazil, one in the US, were hooked up with electrodes implanted in the motor cortex of their brains. The signals were connected over the internet. In order for the mice to get food they both had to operate a lever in their enclosures at exactly the same time. The mice figured it out, and successfully got the food. They were essentially communicating telepathically through the internet.

Yes. There are numerous programs centred around connecting nerve endings of severed limbs to robotic replacements. They have had some success, but not quite to the level of Luke Skywalker robot hands. Other research groups are trying to bypass the nerves and have prosthetics controlled straight from the brain. It is quite possible we will see robotic limb replacements in the next 20-30 years.

As far as I am aware that is above our current capability. We could perhaps make a system that told you when bad liars were lieing, but good liars would be able to beat it.

Very long way off. IBM are kicking some goals in the field (like winning Jeopardy and Chess) but there are still plenty of games AIs can't compete in, let alone life.
