Using implanted electrodes, in two separate experiments, people have been able to control electronic activity outside the brain. :confused:

For me, slightly freaky cyborgperson stuff.



A new attempt to link brains to machines has enabled volunteers to make screen images appear and fade away simply by thinking.

The experiment, conducted in the US, involved 12 epilepsy patients surgically implanted with brain electrodes to locate the source of their seizures.

Neuroscientists used the electrodes to connect individual neurons deep inside the brain to images on a screen.

With practice, the volunteers were able to control the appearance of “hybrid” images consisting of one picture superimposed on another.

On cue they could quickly make a particular image, such as Marilyn Monroe or former US president George Bush, “fade in” or “fade out”.

During the tests, patients worked out their own strategies for conjuring up the right images.

Some simply thought of the picture, while others repeated the name of the image out loud or stared at a particular aspect of the image.

All the participants quickly mastered the task and were successful in around 70% of trials.

Dr Moran Cerf, from the California Institute of Technology (Caltech), who worked on the research reported today in the journal Nature, said: “The patients clearly found this task to be incredibly fun as they started to feel that they control things in the environment purely with their thought.

“They were highly enthusiastic to try new things and see the boundaries of ’thoughts’ that still allow them to activate things in the environment.”

Scientists have previously used the activity of neurons in the brain to control a cursor on a computer screen.

This was also achieved by the Caltech team. By thinking of individual images, the volunteers were able to move a cursor up and down and even play a computer game.

Well it's been said that we only use a fraction of what our brain is capable of. Would you call this a form of telepathy Cactus?

Yes, but we couldn't do it without the electrode. I bit more detail on how it works would be good.

This is a much better description of the experiment.

It's been written that Native Americans couldn't see the ships of Columbus et al as they had no experience to conceptualise what they were witnessing.

Some students of mine had neural impulse interpretation working in DCU in 2002, using slow brain waves called "mu waves" and standard sports science sensors. No surgery - sensors put on the cortex

neural impulse interpretation will soon be standard tech and eg neurosky has been trying to commercialize it
