Rare photos of Einstein’s brain reveal abnormalities that could have contributed to genius
Albert Einstein is widely regarded as a genius, but how did he get that way? Many researchers have assumed that it took a very special brain to come up with the theory of relativity and other insights that form the foundation of modern physics.
A study of 14 newly discovered photographs of Einstein’s brain, which was preserved for study after his death, concludes that the brain was indeed highly unusual in many ways. But researchers still don’t know exactly how the brain’s extra folds and convolutions translated into Einstein’s amazing abilities.
The story of Einstein’s brain is a saga that began in 1955 when the Nobel Prize-winning physicist died in Princeton, N.J., at age 76. His son Hans Albert and his executor, Otto Nathan, gave the examining pathologist, Thomas Harvey, permission to preserve the brain for scientific study.
Harvey photographed the brain and then cut it into 240 blocks, which were embedded in a resinlike substance. He cut the blocks into as many as 2,000 thin sections for microscopic study, and in subsequent years distributed slides and photographs of the brain to at least 18 researchers around the world. With the exception of the slides that Harvey kept for himself, no one is sure where the specimens are now, and many of them have probably been lost as researchers retired or died.
This is good & bad, because we just nday never know & his brain is scarred everywhere for no reason now
Thought-controlled prosthesis is changing the lives of amputees
The world’s first implantable robotic arm controlled by thoughts is being developed by Chalmers researcher Max Ortiz Catalan. The first operations on patients will take place this winter.
“Our technology helps amputees to control an artificial limb, in much the same way as their own biological hand or arm, via the person’s own nerves and remaining muscles. This is a huge benefit for both the individual and to society”, says Max Ortiz Catalan, industrial doctoral student at Chalmers University of Technology in Sweden.
Ever since the 1960s, amputees have been able to use prostheses controlled by electrical impulses in the muscles. Unfortunately, however, the technology for controlling these prostheses has not evolved to any great extent since then. For example, very advanced electric hand prostheses are available, but their functionality is limited because they are difficult to control.
“All movements must by pre-programmed”, says Max Ortiz Catalan. “It’s like having a Ferrari without a steering wheel. Therefore, we have developed a new bidirectional interface with the human body, together with a natural and intuitive control system.”
Today’s standard socket prostheses, which are attached to the body using a socket tightly fitted on the amputated stump, are so uncomfortable and limiting that only 50 percent of arm amputees are willing to use one at all.
This research project is using the world-famous Brånemark titanium implant instead (OPRA Implant System), which anchors the prosthesis directly to the skeleton through what is known as osseointegration.
“Osseointegration is vital to our success. We are now using the technology to gain permanent access to the electrodes that we will attach directly to nerves and muscles”, says Max Ortiz Catalan.
Hope they dont start truong to make robots that function by our thoughts…

All I’m saying is, this would make the world’s best tire swing.
Yes it would & you could swing like tarzan to!
