Brain to Muscle Link in the Monkey

I am a little late to this party, but I do want to talk about this paper in Nature Neuroscience. Moritz et al. implanted an electrode into a monkey’s motor cortex. The electrode was designed to only record from a single neuron at a time. Then the output of that cell — after a little…

Here is a different approach to measuring brain activity in humans. Researchers in Japan are placing a sheet of electrodes inside the skull but on top of the cortex. Researchers at Osaka University are stepping up efforts to develop robotic body parts controlled by thought, by placing electrode sheets directly on the surface of the…

Doctors at the University of Navarra have implanted an auditory brainstem implant (ABI) in the youngest patient ever attempted — a 13 month-old girl: A team of ear, nose and throat specialists and neurosurgeons at the University Hospital of Navarra, led by doctors Manuel Manrique Rodriguez, specialist in ear, nose and throat surgery and Bartolome…

Totally effective, side-effect free treatment of Parkinson’s continues to elude physicians, but a study by Deuschl et al in the NEJM shows that we are definitely making progress. Deuschl et al performed a randomized study that assigned patients into one of two groups. The control group recieved the standard treatment for Parkinson’s — which right…

The most recent issue of Nature has a paper by the Donoghue lab at Brown about their project implanting an ensemble of electrodes into the motor cortex of a paraplegic. Signals from the electrodes were decoded and used to run a computer program so the patient can literally move the cursor with their mind. This…

Misha at Mind Hacks has a great update on brain-computer interface advances.

Neuroprosthetics

Popular Science has a great article on the recent advances in prosthetics. They hit on one of the topics that I think has been really under-researched: neural to machine interfaces. What you would really like to do with a prosthetic is have it communicate directly to and recieve information directly from the central nervous system.…
