Yes. but not quite what you think. They are currently working with monkeys on a thought controlled artificial limb. They have a small electrode implanted into the brain of a monkey. This electrode detects signals that are generated by the monkeys brain when it reaches for something. The signals are processed by a computer that has a robotic arm attached to it. They sit the monkey in a chair, restrain his arms down and then offer the monkey marshmellows. The monkey learns that they can control the robotic arm just by thinking. It only takes 3 or so days for the monkey to get the hang of it. The next step is to add more flexibility andd fingers to the arm. This is hoped to lead to lifelike replacement limbs for amputees.

No. The electrical signals picked up on the scalp (EEG) only represent averaged activity of the surface layer of neurons. Implanted electrodes could in theory detect the activity of groups of neurons deeper in, but that would obviously be much more invasive and risky. Some areas of the brain could never be accessed by any of these means. PET scans fMRI are methods of assessing which parts of the brain are working the hardest according to glucose uptake, blood flow, or other markers of metabolism. All of these methods yield crude information about brain activity. Reading "thoughts" (detecting, let's say, a secret password that the subject is told to think about) is completely impossible today. Not only is it limited by technology, but nobody knows how specific thoughts are actually encoded and implemented. We don't even know how memories are stored. Give it another two or three centuries of research!

I'm sure the machine will be able to measure moods or basic modes of thought based upon where the electricity is coming from but not the exact thoughts themselves.

60 Minutes had a report that seems like science fiction: Mind reading for real. Neuroscientists at Carnegie Mellon University used a computer and a functional MRI to read the mind of a CBS producer. http://www.huffingtonpost.com/2008/12/30/60-minutes-mind-reading-f_n_154370.html The subject was shown ten images (e.g. screwdriver, window, apartment building, etc.) while a computer noted which areas of the brain lit up on an MRi scan when each image was displayed. All ten images were correctly identified by the computer.

I read an article the other day about scientists in Asia that are developing a machine that can apparently put your dreams onto a computer screen so you can watch them like a movie. It seems a little far fetched to me but I suppose almost anything is possible these days.

yes there is its called a mind imager and it is scary
-
its called a mind imager its real i know because im a victim of it

They have created a device where a paraplegic can move the cursor on a computer screen with his mind. http://www.scientificamerican.com/article.cfm?id=tiny-chip-converts-parapl

I DOUBT IT, BUT PEOPLE IN THE NORTHWEST CAN READ OTHER PEOPLE'S MINDS AND OTHER THINGS WITH THEIR E.S.P., I BELIEVE THEIR BORN WITH IT. MY EXPERIMENTS PROVED THIS IS VERY TRUE.

I DOUBT IT, BUT PEOPLE THAT LIVE IN THE NORTHWEST AND NORTHEAST HAVE E.S.P. AND CAN READ OTHER PEOPLE'S THOUGHT. I PROVED IT 3 TIMES.
