LUNTIC DODGEMS. “Here we show that rhesus monkeys can learn to navigate a robotic wheelchair, using their cortical activity as the main control signal....monkeys employed the wireless BMI to translate their cortical activity into the robotic wheelchair’s translational and rotational velocities.” https://lnkd.in/ddkn2wJ View in LinkedIn

MONKEY DATA. “We demonstrate for the first time that kinesthetic feedback can be used together with vision to significantly improve control of a cursor driven by neural activity of the primary motor cortex (MI). Using an exoskeletal robot, the monkey's arm was moved to passively follow a cortically controlled visual cursor, thereby providing the monkey with kinesthetic information about the motion of the cursor.” http://www.jneurosci.org/content/30/50/16777.full View in LinkedIn

EARLY RESULTS. “We demonstrate for what we believe is the first time the ability of the same ensemble of cells in closed-loop mode to control two distinct movements of a robotic arm: reaching and grasping. In addition, we demonstrate how the monkeys learn to control a real robotic actuator using a BMIc.” (BMIc = brain–machine interface). http://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.0000042 View in LinkedIn

BRAIN-MACHINE INTERFACE. “Here we demonstrate that primates can learn to reach and grasp virtual objects by controlling a robot arm through a closed-loop brain–machine interface (BMIc) that uses multiple mathematical models to extract several motor parameters (i.e., hand position, velocity, gripping force, and the EMGs of multiple arm muscles) from the electrical activity of frontoparietal neuronal ensembles.” https://lnkd.in/d4WXCSr View in LinkedIn

EARLY MONKEY DATA. “The activity of motor cortex (MI) neurons conveys movement intent sufficiently well to be used as a control signal to operate artificial devices, but until now this has called for extensive training or has been confined to a limited movement repertoire. Here we show how activity from a few (7–30) MI neurons can be decoded into a signal that a monkey is able to use immediately to move a computer cursor to any new position in its workspace.” https://lnkd.in/d-wie9E View in LinkedIn

SENDING THOUGHTS. “IBM has various prototypes that read electrical impulses in parts of the brain associated with movement. In 2010 ZDNet UK visited an IBM research laboratory and was able to drive a remote-controlled car by 'thinking' of the direction it should go in.” https://lnkd.in/d93j7cx View in LinkedIn

FRAGMENT FROM NATURE deals with the genetic phenomenon called alternative splicing. By this mechanism, organisms can significantly amplify the number of proteins at their disposal, with a relatively small number of genes, thus making these new proteins available for adaptation and new functions. This illustrates how nature has arrived at an ingenious solution to generate, once again, the many from the few. View in LinkedIn

DURABLE IMPLANTS. “Two monkeys with brain implants have steered wheelchairs using only their minds, researchers said Thursday, in another step forward for a field seeking to mobilize people with paralysis. And the brain implants that made the mind-to-computer interface possible have lasted in the monkeys for seven years.” https://lnkd.in/dQvunCh View in LinkedIn

MEDICAL USES. “BrainGate that allows fully paralyzed patients to control devices with their thoughts. BrainGate works by inserting a small chip, studded with about 100 needlelike wires—a high-tech brush—into the part of the neocortex controlling movement. These motor signals are fed to an external computer that decodes them and passes them along to external robotic devices.” http://www.wsj.com/articles/SB10001424052702304914904579435592981780528 View in LinkedIn
