Is amazing what they can do with brain implants nowdays...

Brain implants help paralyzed man drink coffee on his own for 1st time in years
Mar 28, 2017, After years of paralysis, a man was able to pick up a cup of coffee and take a sip, thanks to experimental technology that allowed brain signals to control his arm with the help of a computer.

The researchers at Case Western Reserve University and University Hospitals Cleveland Medical Center documented their work in a new study published today in The Lancet medical journal. The study explains how a special electrical device, including implants in the brain and arm, allowed the man to control the movement of his right hand and arm years after being paralyzed from the shoulders down. Dr. A Bolu Ajiboye, assistant professor of biomedical engineering at Case Western Reserve University and lead study author, explained their patient was the first to have such a high level of paralysis and yet still be able to move his arm via the device called BrainGate2. "He literally cannot do anything on his own," said Ajiboye of the study subject, who was paralyzed eight years before he took part in the study. "With [this] system, he's been able to scratch his nose or be able to take a take a drink of a cup of coffee ... he now has the ability to do things."

To help the unnamed patient, doctors used the experimental neural interface system, BrainGate2, which is being studied in clinical trials at various institutions in the U.S. The system works by using electrical chips in the brain to transmit data to a computer, which then sends electrical signals to the muscles to move. In this case, two small chips were implanted in the man's brain in order to transmit data via a cable to a computer. The researchers also implanted small electrodes in his right arm, so that electrical impulses can cause the muscles to move. In a person with full mobility, a desire to move the arm will result in an electrical signal down the spinal cord to the muscles that will result in the arms moving. The devices recreates that by having the implant "read" data from the patient's brain, which the computer translates into action that is then triggered by electrical signals to implants in the patient's arm. "What we are doing in this project is circumventing the spinal injury by taking [the] pattern of brain activity to directly stimulate the muscles," Ajiboye explained.

Ajiboye said the patient was excited to take part in the study despite the invasive surgery in order to be able to do things for himself again. "He said, 'You know what I really want to [do is] drink coffee,'" Ajiboye recalled. "We showed him drinking through a straw and drink coffee [via the device]." He also has gotten to feed himself and even itch his nose with the device. However, since the device is experimental, the patient can only use it in the lab, but researchers hope to eventually have a device that he can use at home. "He definitely keeps us wanting to innovate," said Ajiboye. "We want to give him more functionality."

Dr. Ben Walter, medical director of the Deep Brain Stimulation Program at University Hospitals Cleveland Medical Center and co-author of the study, said that this is still an early prototype with limitations. For example, the patient can't "feel" what he's holding; instead, he has to visually judge how much force to use in order to pick something up. "In this particular application, he is not sensing the pressure and able to modulate the force based on feedback," Walter explained. "He can see what he's doing, but he can't feel." While experimental, Walter said the implant is still an important move forward and could become much more streamlined in the future. "In this case, he just thinks about moving and he moves," Walter said. "We're really putting things back together the way they're meant to be."

They have come far in the advances of (I may get this term wrong) Electro-neural impulse. Those who have been impaired or lost the connection that fires the muscular response, have received implants and other means of inducing the electrical impulse that helps them with movement.

I'm not fully versed in all the terminology, so please forgive. I was told the basics when someone I know was having to go through some of this after a car accident had severed (?) nerves from the brain to their legs.

That being said, when I saw Brain Salad Surgery, I was thinking someone posted a ELP video.

Cap-like device that makes electric fields to fight cancer improved survival...

'Sci-Fi' Cancer Therapy Fights Brain Tumors, Study Finds
April 02, 2017 | WASHINGTON — It sounds like science fiction, but a cap-like device that makes electric fields to fight cancer improved survival for the first time in more than a decade for people with deadly brain tumors, final results of a large study suggest.
Quote:
Many doctors are skeptical of the therapy, called tumor treating fields, and it's not a cure. It's also ultra-expensive - $21,000 a month. But in the study, more than twice as many patients were alive five years after getting it, plus the usual chemotherapy, than those given just the chemo - 13 percent versus 5 percent. “It's out of the box” in terms of how cancer is usually treated, and many doctors don't understand it or think it can help, said Dr. Roger Stupp, a brain tumor expert at Northwestern University in Chicago.

He led the company-sponsored study while previously at University Hospital Zurich in Switzerland, and gave results Sunday at an American Association for Cancer Research meeting in Washington. “You cannot argue with them - they're great results,” and unlikely to be due to a placebo effect, said one independent expert, Dr. Antonio Chiocca, neurosurgery chief at Brigham and Women's Hospital in Boston. Dr. George Demetri of the Dana-Farber Cancer Institute in Boston and a board member of the association hosting the conference, agreed but called the benefit modest, because most patients still die within five years. “It is such a horrible disease” that any progress is important, he added.

About the treatment

The device, called Optune, is made by Novocure, based in Jersey, an island near England. It's sold in the U.S., Germany, Switzerland and Japan for adults with an aggressive cancer called glioblastoma multiforme, and is used with chemo after surgery and radiation to try to keep these tumors from recurring, as most do. Patients cover their shaved scalp with strips of electrodes connected by wires to a small generator kept in a bag. They can wear a hat, go about their usual lives, and are supposed to use the device at least 18 hours a day. It's not an electric current or radiation, and they feel only mild heat. It supposedly works by creating low intensity, alternating electric fields that disrupt cell division - confusing the way chromosomes line up - which makes the cells die. Because cancer cells divide often, and normal cells in the adult brain do not, this in theory mostly harms the disease and not the patient.

What studies show

In a 2011 study, the device didn't improve survival but caused fewer symptoms than chemo did for people whose tumors had worsened or recurred after standard treatments. The U.S. Food and Drug Administration approved it for that situation. A second study, in newly diagnosed patients, was stopped in 2014 after about half of the 695 participants had been tracked for at least 18 months, because those using the device were living several months longer on average than the rest.

The FDA expanded approval but some doctors were leery because the device wasn't compared with a sham treatment - everyone knew who was getting what. Study leaders say a sham was impractical, because patients feel heat when they get the real thing, and many would refuse to shave their heads every few days and use an inconvenient device for years if the treatment might be fake. Some doctors said they would withhold judgment until there were long-term results on the whole group.
