New technological processes that allowed the development of ever smaller and more performing electrodes and simultaneously the advancement of research in AI field has made possible to integrate machine with human body, leading to significant progress in neuroscience field. This new technology is expected to allow neuroscientists to make great strides working on brain signals decoding where large number of channels are generally required as in the case of EEG and in particular of ECoG. Eventually, this progress is expected to lead to a new generation of brain-computer Interfaces (BCIs) that have the potential to restore lost sensory motor function, caused for example by spinal cord injury or neurodegenerative disease.
