Document Summary
Brain machine interfaces: basic science to neurological rehabilitation. Edmond and lily safra international institute of neuroscience of natal, brazil. Problem with neuroscience: only recording one neuron at a time, need to study how the billions of neurons (10 billion) interact. 100 neurons recorded of a monkey"s hand grasping movements. Recording sensors used in machines that can be implanted in brain tissue, 3d printed, made with microfilaments. Able to record action potentials via hairlike filaments placed b/w cells. Created brain machine interface: links living brain tissue to devices with wireless control so that brain activity can control anywhere this device is located. Ex. monkey studied in durham able to control robot arms in japan. Moore"s law for number of neurons studied simultaneously!!! Same as what we discussed regarding computer chips and storage!! Designed bmi to strap a monkey to a recording machine and toggle a lever to hit a flashing circle. Brain control can be achieved even without arm movements.
