The study, conducted by an international research team which also participated in the Psychology Department of Milano-Bicocca, italy, has shown that our brain applies the tactile perception of the body to an object, such as an extension of the body. The experiment opens up new avenues for the realization of prosthesis more and more precise, able to adapt to your body. It has been shown that to recognize the exact position of the impacts on the stick can also a person devoid of sensibility to an arm, thus confirming that the impacts on the instrument are encoded only through the mode of touch.
"These results," commented Nadia Bolognini , professor of Psychobiology and physiological psychology, Milan-Bicocca and co-author of the study - suggest that it will be possible in the not too distant future, designing neuro-prostheses, less-invasive and high-performance generating them touch signals that provide optimal answers in the contact with the objects. This could be achieved by exploiting the mechanism identified in our study, which will allow the patient to localize tactile stimuli on a prosthesis in a natural way and facilitado so the use of the prosthesis as if it were a real sensory organ extended".
