swarms of ultra thin nano scaled electrodes can cross the blood brain barrier without a 'carrier's" consent or knowledge
Connecting a human brain to a computer is as much a materials science problem as a biology one. What kind of interface is delicate enough not to damage nerve tissue, but resilient enough to last decades?
Researchers have come up with what they call a “stealthy neural interface” made from a single carbon fiber and coated with chemicals to make it resistant to proteins in the brain.
“We wanted to see if we could radically change implant technology,” saysTakashi Kozai, a researcher at the University of Pittsburgh and the first author on the paper, published today in the journal Nature Materials.Researchers need long-lasting electrodes in order to improve brain-machine interfaces. see “New Brain Machine Interfaces”).
The latest work, done in the University of Michigan’s Neural Engineering lab, was led by Daryl Kipke, a researcher who is also CEO of a company, NeuroNexus, that sells neural recording equipment. Kipke said a patent application had been filed on the work.
*A micrometer (sometimes expressed using the obsolete term, micron ), is one-millionth of a meter and can also be expressed as:
- 10 -6 meter
- One thousandth of a millimeter
- One 25-thousandth of an inch
A human hair is said to be about 50 micrometers wide.
Phineas P. Gage (1823–1860)"the original "Lawnmower Man" was an American railroad construction foreman remembered for his improbable survival of a rocking blasting accident in which a large iron rod was driven completely through his head, destroying much of his brain's left frontal lobe, and for that injury's reported effects on his personality and behavior over the remaining 12 years of his life, effects so profound that (for a time at least) friends saw him as "no longer Gage".
