Paralyzed Patient Communicates with Brain Implant
Brain-machine interfaces continue to advance.
Adding Sensation to Robotic Limbs
Recently scientists have managed to stimulate the brain in such a way that approximated some of the sensations of a natural limb in a paralyzed subject. No, they did not regain sensation, but the research is a powerful proof of concept. It shows that it is possible to produce natural-feeling sensation through electrical stimulation of the cortex, an important step for brain-machine...
Communicating with the Locked In (update)
Researchers have made an incremental advance in using imaging and computers to communicate with patients who are completely locked-in. Let's review the state of this technology.
Bad Reporting about Uploading Memories
The Mirror declares, ‘Scientists develop Matrix-style technique of ‘feeding’ information directly into your brain.’ Discovery News went with, “Novices ‘Download’ Pilots’ Brainwaves, Learn To Fly.” Most other outlets spoke of ‘uploading’ information to the brain, and learning in seconds. The one thing I was certain of from reading these headlines is that this was not what was happening. Brain-machine interface technology is...
Helping the Paralyzed Walk
One of our primary goals at SBM is to advocate for high standards of science in medicine. This means that we spend a lot of our time discussing claims and practices that fall short of this standard. This is very useful – exploring exactly why a claim falls short is a great way to understand what the standard should be and why....
Hacking the Brain – A New Paradigm in Medicine
The word “paradigm” is over misused and overused, diluting its utility. Thomas Kuhn coined the term in The Structure of Scientific Revolutions to refer to an overarching explanatory system in science. Scientists, according to Kuhn, work within a paradigm during periods of “normal science,” punctuated by occasional “paradigm shifts” when the old explanatory model no longer sufficed, and a radically new explanatory...
Brain-Machine Interface
We spend a great deal of time in the pages of Science-Based Medicine taking down every form of pseudoscience in medicine. Of course, what we see as pseudoscience, proponents often see as emerging or cutting edge science. They are taking advantage of the fact that there is a great deal of legitimate emerging science, and they hope they can sneak past the...
Communicating with the Locked-In
Facilitated communication is exploitation supported by false hope and good intentions. Brain-machine interfaces are progressing with agonizing slowness, but offer true potential in actually permitting paralyzed people to communicate and even regain movement.
