Details of To imagine thought 2

The neuroscienza will read in the thought, directly in the brain, as it was a code to decipher. It is what they support John-Dylan Haynes, of the Max Planck Institute for Human Cognitive and Brain Sciences di Lipsia, and a team of Japanese and English investigators, that they have lead one study published on Current Biology. "the intentions R-with regard to the future and programmed activities do not reside in single neurons, but they are codified in an entire area of the brain", has asserted Hayes. For monitorare and interpreting the cerebral activity that brulica in this area, in the front part of the corteccia prefrontal of the brain, is enough of the complex algorithms and a machinery for the magnetic resonance works them.

The experiment that has demonstrated it is served of eight volunteers, to which it has been entrusted one chosen R-with regard to the removal or to the sum of two numbers: before still that the numbers on which operating they came reveal to you, before still that the intention was translate in action, moment in which the cerebral activity it is moved hardly in the region of brain situated behind that front prefacade, the neuroscienziati ones are resolutions to read the intentions to embezzle or to add, observing like in the cerebral area are activated determine to you pattern, of the outlines that they differ and they resort with regolarità, based on the various intentions of the subjects. After forty minuteren of training based on "the analysis and the location of varying of parameters in the cerebral maps emerged from the scansions of the brain multivaried pattern recognition" (), the computers have learned to recognize the various outlines of cerebral activity, preconizing the actions put in action from the subjects, with succeeding 70% of.

The neuroscienze already catch a glimpse revolutionary developments. Haynes, interviewed from LiveScience, has spoken about a future in which the multivaried ones pattern recognition it will be able to be applied to the videogiochi, in order to amplify the experience of immersion in the game (experiment, moreover, already carried out, ndr). At the moment, but, the costs would be forbidden to you, since a machinery for the magnetic resonance works them not coast less than two million than dollars. Hayes thinks also to applications in the within of prostheses for the disabilità motorie, showing able neurali interfaces to receive commandos from the brain directly.

The reading of the thought, al.di.là.della found sensational, still remains fantascienza, even if the neuroscienziati ones of sure will not abandon the plan. To the fair for the medical equipment of Dusseldorf, in Germany, it has been introduced the interface for the "Brain Computer", an able computer science device to transform the thoughts in words, visualizzabili on the screen. The plan, called "g.EEGcap", is of the g.tec, a company that has studied a system of electrodes to apply, through a caschetto, to the head of the customers. That, incredibly, they will be able to see on the screen of portable the own thoughts, like shown from some photos that turn on the net. At the moment, they are ignored is the times necessary in order to complete the plan is the eventual cost of the apparatus.

To the University of Padova, Giuseppe Sartori, teacher of cognitive neuroscienze, new machine has planned one of the truth, based on the times of answer and the unconscious associations, in a position to giving a percentage of exact answers that goes from the 90 to 93% (in phase of advancing experimentation). A 10-13% in more regarding blots some traditional, based on parameters which the cardiac variations, the pressure and the sudorazione, than they are stopped to 80%. The machine has been head up to now on a some thirty of criminals already judges to you, on as many victims and approximately 300 subjects of laboratory, all volunteers.

The system is considered from the new and revolutionary scientific world. And someone is already ready to bet that the world of the "lie will channel in one new direction detection". From the scientific point of view, the initiative of the padovano teacher represents one absolute innovation. They do not serve will inhibitor vials, they do not serve drugs more or less dangerous for the health in order to make to speak the suspicion. And even if suda to excess, and you strike yourself of its turned out heart accelerates to you, even for a cardiac problem, or a strongest moment of emotional stress, the padovana machine does not let to trick. "the system is based on the times of reaction and of answer of the suspected one" Giuseppe Sartori explains.

A simple computer and a dedicated program are, that is, in a position to completing those miracles that until much time it does not perform were not not even imaginable. Monica Marchetti, expert psychologist in psicopatologia forense watches already to the future. And it says: "If this machine of the truth had to work indeed it would mean that we are in order to send in attic a lot of that it has been made until today. Insomma: they could it are to us little test it projects to you, little directed observation on the suspected one and sinks more express towards the heart of the problem ".

For the report, they are in via of sperimentrazione also blots some of the truth based on the technique of the magnetic resonance works them (fMRI).
