Telepatia... artificiale!

Charles Xavier degli X-Men

La telepatia è, secondo la definizione del vocabolario, la facoltà di trasmettere o percepire messaggi senza l’uso dei sensi. Ad oggi, secondo la comunità scientifica, there is no satisfactory evidence that there are people with telepathic abilities.

However, there are people unable to move and speak in a very serious because paralyzed as a result of serious injury or terrible diseases such as ALS (amyotrophic lateral sclerosis ) that they would derive great benefits from telepathy.

On the site of "Le Scienze", the Italian version of Scientific American's news absolutely fascinating to me. In short, a group of researchers at the University of Utah, conducted by Bradley Greger published an article on Journal of Neural Engineering which explains a technique for decoding words by patients think reading the electrical potential of the cortical surface of the brain ...

I quote the abstract of the article:

pathological conditions such as ALS (amyotrophic lateral sclerosis) or damage to the nervous system can sink patients, severely paralyzed but fully conscious, in a condition called locked in syndrome . The disclosure in these cases is often reduced to select letters or words one at a time using the movements with residual fatigue. A more intuitive and faster communication could be restored by interfacing directly to the areas of language the cerebral cortex.

We used a grid of micro electrodes close together and not penetrating to record local electrical potential (local field potentials or LFP) directly on the facial motor cortex and Wernicke's area. From these LFP we were able to successfully classify a small set of words at levels much higher than pure chance.

The prototype captures the brain signals through two grids of 16 micro-electrodes implanted beneath the skull without penetrating the cortex in two brain areas known to be centers of language and was tested on a patient with severe of epilepsy. The patient repeated

Sometimes a more than ten words and the researchers recorded data from grids, computer processing to recognize patterns of neuronal activation corresponding to each word.

The items selected for the experiment were those that might be more useful to a patient completely paralyzed: yes, no, more, less, hunger, thirst, cold, heat, hello and goodbye.

The experiment showed that the most requested when patients had pronounced the words the facial motor cortex, involved in the control of facial muscles to produce sound, while the area of \u200b\u200bWernik was activated more when the patients were thanked by researchers, indicating the involvement of this part of the brain in high-level understanding of language.

The researchers found that the patterns of activity concerned in different ways different columns of neurons below the electrodes.

The identification of words is not yet perfect, but well above the pure randomness (ie recognizing a word out of 10 with a precision much higher than 10%, the percentage that would be obtained guessing), and researchers think of using for the next step of the grids with multiple elements (121 per grid), which can provide huge amounts of data from which should be possible to obtain not only greater accuracy but also the recognition of more words.

irony of fate, while the parapsychology has not yet been able to demonstrate in a scientifically acceptable that someone can read your mind, the much insulted "official science" begins to really do it!
