Scientists Develop Cyborg Interface Algorithm 110

Posted by Zonk from the universal-man-machine-interface dept.
StCredZero writes "A ZDNet article discusses advances in the translation of brain activity to electronic control being made at MIT. Their approach allows a paralyzed individual to manipulate a prosthetic - but that's not the important advance. 'Other scientists have already done that, and built prototypes for neural brain-to-machine devices that can work for animals or humans. But each team has taken a different approach to the problem, such as developing algorithms for measuring activity in a specific brain region, or measuring them through EEGs vs. optical imaging. MIT said that it has developed a unified algorithm that can work within the parameters of these different approaches. Lakshminarayan "Ram" Srinivasan, lead author of a paper on the subject, said MIT's new graphical models are applicable no matter what measurement technique is used. "We don't need to reinvent a new paradigm for each modality or brain region," he said in a statement.'"

      Actually, it's pretty funny you bring that up, as there's a Ghost In The Shell episode [wikipedia.org] in which this very sort of situation occurs.

      A man with cybernetic limbs shoots and kills a woman. During the court trials, his defense lawyer (highly experienced with defending people with cybernetic prosthetics) says that the defendant wasn't used to his newly upgraded/installed cybernetic body parts (and the new control software for them) and thus fired the gun unintentionally.

      When I saw this episode, it was a bit of a shock to consider those kinds of situations where the natural self-control we take for granted could potentially no longer be in place, if we were to start to rely on technology to take the place of our physical bodies...
      • Why do we make the assumption that humans are inherently more reliable in controlling their own body than some alternative interface? I suppose the problem is that we have nothing with which to compare. We can't look at how many people simply go crazy and kill people and compare that percent to how many cyborgs do the same. Damn you ethics. I want my chainsaw arms now.
        • it's not an "assumption" that it's "inherently" more reliable. It's a practical reality that there is no interface as reliable as the one we are born with, in large degree because every interface we have so far built or conceived of uses the existing one in some way and tries to interpret the results and thus are -at least- as unreliable as our own body interface.

    General Purpose Filter Design for Neural Prosthetic Devices [physiology.org]

    Lakshminarayan Srinivasan1*, Uri Tzvi Eden2, Sanjoy K. Mitter3, and Emery N Brown

    Brain-driven interfaces depend on estimation procedures to convert neural signals to inputs for prosthetic devices that can assist individuals with severe motor deficits. Previous estimation procedures were developed on an application-specific basis. Here we report a coherent estimation framework that unifies these procedures and motivates new applications of prosthetic devices driven by action potentials, local field potentials (LFP), electrocorticography (ECoG), electroencephalography (EEG), electromyography (EMG), or optical methods. The brain-driven interface is described as a probabilistic relationship between neural activity and components of a prosthetic device that may take on discrete or continuous values. A new estimation procedure is developed for action potentials, and a corresponding procedure is described for field potentials and optical measurements. We test our framework against dominant approaches in an arm reaching task using simulated traces of ensemble spiking activity from primary motor cortex (MI), and a wheelchair navigation task using simulated traces of EEG-band power. Adaptive filtering is incorporated to demonstrate performance under neuron death and discovery. Finally, we characterize performance under model misspecification using physiologically realistic history dependence in MI spiking. These simulated results predict that the unified framework outperforms previous approaches under various conditions, in the control of position and velocity, based on trajectory and endpoint mean squared errors.
