Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

DARPA Wants to Hack Your Brain to Make You Learn Faster

A great stroke association would take the results from here and create a stroke protocol to get survivors 100% recovered. But since we have fucking failures of stroke associations instead this won't be occurring. You are on your own. 

DARPA Wants to Hack Your Brain to Make You Learn Faster


If the brain is just a bunch of wires and circuits, it stands to reason that those components can simply be re-wired in order to create a better, smarter us. At least, that’s the theory behind a new project from the military’s secretive DARPA research branch announced on Wednesday, which aims to enhance human cognitive ability by activating what’s known as “synaptic plasticity.”
Recent research has suggested that stimulating certain peripheral nerves—those that relay signals between the brain, the spinal cord and the rest of the body—can enhance a person’s ability to learn, by triggering the release of neurochemicals that reorganize connections in the brain. Through its new Targeted Neuroplasticity Training program, DARPA is is funding eight different research efforts that seek to enhance learning by targeting those nerves with electrical stimulation. The end goal is to translate those findings into real-world applications that boost military training regimens—allowing a soldier, to say, soak up a new language in months instead of years. Should DARPA figure out a way to do that, its efforts will likely go on to impact all of us.
“TNT aims to deliver new knowledge of the neural processes that regulate cognitive functions associated with learning,” Doug Weber, the program’s manager, told Gizmodo. In other words, DARPA wants to study the basic biology at work here, and eventually, design neurostimulation devices that exploit our biological wiring to enhance learning.
One DARPA-funded team, at Johns Hopkins University, will focus on speech and hearing. These researchers will be experimenting with vagal nerve stimulation, exploring whether this can accelerate learning a new language. Another team at the University of Florida will study how vagal nerve stimulation impacts perception, executive function, decision-making, and spatial navigation in rodents. Yet another at Arizona State University will stimulate the trigeminal nerve, and study how that impacts visual, sensory and motor functions of military volunteers studying intelligence, surveillance, reconnaissance, marksmanship and decision-making.
Already, there are plenty of products on the market that claim to offer cognitive, psychological, and physical performance enhancement. (Basketball’s Golden State Warrior’s, for one, are known to rely on brain-zapping for a purported edge in their game.) But there is little understanding of how these devices work—and many scientists suspect they don’t. The aim of the DARPA program is to settle this debate, testing the efficacy of both implanted and non-invasive devices to understand not only whether they actually work, but if so, how.
“We are starting with a bit of knowledge about how the peripheral nerves are wired, but relatively little knowledge about the effects of neurostimulation on their function,” Weber said.
If, it turns out, there is a sufficient link between neurostimulation and improvements in learning, the second phase of the program will work to design devices that enhance training in foreign language learning, image analysis, and spatial navigation tasks.
“Most computer analogies for the brain idea are bad,” said Michael Kilgard, the lead researcher on the University of Texas at Dallas project. “But there really are wires from point A to point B. When you cut those wires you lose function. But after they’re cut they can make new connections. We have technologies now that allow us to see those connections.”
Kilgard’s work has, until recently, focused on repairing damaged circuits. Areas of research like deep brain stimulation (which involves implanting a chip deep in the brain) and transcranial direct stimulation (which changes brain chemistry using non-invasive electrical stimulation) have seen some success in using electricity to correct faulty wiring to, say, help treat mental health conditions. Kilgard has had success using targeted plasticity therapy to treat PTSD.
“Our idea was, after brain injury how do you get better? What you really need is to rewire circuits,” he said. “This is the next logical step. If you can help recover function you’ve lost, can you increase the rate at which you learn new things?”
Eventually, he envisions a device that, for a few hundred bucks, will non-invasively allow anyone to pick up a language at an accelerated pace. Under the current grant, he hopes to in five years have a (likely much more expensive) version of that device ready for FDA approval.
But there are plenty of hurdles. For one, that any of this will even work is still little more than an educated guess.
“We are leveraging state-of-art tools for probing the molecular and cellular processes underlying these functions, but even the most advanced instrumentation is limited,” said Weber.
What’s more, the very premise of the research is likely to stoke fears that DARPA is creating a race of cognitively enhanced super soldiers. The agency has several other brain projects in the works, which seek to use implanted chips to treat mental illness as well as to restore memories and movement to battle-wounded soldiers. For now, the aim of the program is to just give our brain’s a little boost—allowing us to learn a new skill maybe, say, 30% faster than we would naturally. But even the use of brain stimulants like Ritalin or Modafinil readily available on today’s college campuses is controversial.
Critics argue that such enhancement defies human nature. Supporters say that seeking out enhancement is human nature. The new research makes this debate, on how far we as a society are willing to take human cognitive enhancement, all the more urgent.
“Issues related to safety, equal access to the technology, and freedom of choice are often the earliest topics considered when new, breakthrough technologies are created,” Weber said. “It’s important that we carefully consider the broader impact of this work.”

New Exoskeleton Suit from UC Berkeley Helps Paraplegics Walk

This should be able to be repurposed for hemiplegics if our fucking failures of stroke associations wanted to actually do something for survivors.

http://www.rdmag.com/news/2016/02/new-exoskeleton-suit-uc-berkeley-helps-paraplegics-walk?
By Greg Watry, Digital Reporter
It’s been an over a 10-year journey. In 2000, Univ. of California, Berkeley Prof. Homayoon Kazerooni began working with a team to develop a series of exoskeletons. The research was funded by the Defense Advanced Research Projects Agency (DARPA).
Recently, SuitX, founded by Kazerooni and spun off from the university’s Robotics and Human Engineering Laboratory, unveiled the Phoenix, a 27-lb exoskeleton that can help paraplegic users achieve a walking speed of 1.1 mph.
“We can’t really fix their disease,” said Kazerooni. “We can’t fix their injury. But what it would do is postpone the secondary injuries due to sitting. It gives a better quality of life.”
Adaptable to a users’ size, the Phoenix, on a single charge, can walk for four hours continuously, or eight hours intermittently. The battery is stored in a backpack carried by the user.
The exoskeleton is controlled by users via crutches, which are outfitted with buttons, allowing the user to control standing up, sitting down, and walking.
The Phoenix costs around $40,000. While that’s a hefty price tag, it’s more affordable and lightweight than competitors like the ReWalk suit, which costs around $70,000 and weighs 50 lbs, according to MIT Technology Review.  
Kazerooni told the media outlet that one of the goals is to design a Phoenix model for children, which may be able to assist in walking training for those with neurological disorders.
“My injury came about from a BMX bicycle accident,” said Steven Sanchez, one of the Phoenix’s test pilots, in a video. Sanchez’s fall resulted in him breaking his back. He was paralyzed instantly.
“I feel much more with myself and human-like being in this device, being able to stand up eye-to-eye with somebody,” Sanchez said in the video, while footage of him kicking a soccer plays. “It’s strange that this robot makes me feel more a part of this planet than a wheelchair does.”
As the technology continues to advance and the price decreases, these devices may one day be monetarily feasible options for paraplegics.

DARPA’s Humanoid Robots Take a Slow-Motion Leap Forward

I'm not that interested in the robots even though they are cool. I'm interested in The Challenge. Which is something a great stroke association would do to get solutions to all the problems in stroke.
Or we could have the NINDS put this challenge out;

Stroke goals in 10 years


ASA, NSA, WSO; Are you all f*cking afraid of doing something like this? Which might make you obsolete? A stroke survivor would gladly run the organization to make itself obsolete.
https://www.yahoo.com/tech/darpas-humanoid-robots-take-a-slow-motion-leap-121243370784.html
So DARPA did what DARPA does best: It offered a Challenge, open to anyone daring enough to enter — universities, companies, or individuals. It offered $3.5 million in prizes to teams who could successfully complete eight tasks in a simulated power-plant rescue scenario:
1. Drive a vehicle to the plant, stop and park; 
2. Get out of the car; 
3. Walk to the plant’s doorway, open its human-sized handle, and walk through; 
4. Turn a valve handle one full rotation; 
5. Pick up a power drill, turn it on, and cut a hole out of a sheetrock wall big enough for a person to escape; 
6. Climb over (or push aside) a room full of rubble;
7. Exit by climbing a metal staircase; and
8. A surprise task.

Work Begins on Brain Stimulator to Correct Memory - stroke uses?

Maybe in the future when we have a great stroke association that has a stroke strategy to solve all the problems in stroke will this finally come to fruition.
http://www.technologyreview.com/news/536331/work-begins-on-brain-stimulator-to-correct-memory/
For some of the approximately 10 million people worldwide with traumatic brain injury (TBI), forming and holding onto new memories can be one of the hardest things they’ll do in a day. Now imagine a device implanted in the brain that can help them encode memories by means of small electric shocks.
Initial steps toward such a memory neuroprosthetic are being taken at the University of Pennsylvania, where researchers have started tests on brain surgery patients to try to locate, and influence, the processes that control memory formation.
When people suffer brain injuries, several things happen. Neurons might be damaged from the initial impact or from bruising or swelling in the brain afterward. The axons that connect brain regions might be severely jarred during impact, in some cases literally separating from neurons.
The brain is “a complex network of neurons that all have to communicate with each other,” says Matthew Kirschen, a pediatric neurologist at the Children’s Hospital of Philadelphia, who is not involved in the Penn research. “All you need is a little disruption in axonal process and memory is impaired.”
The Pennsylvania team is one of several in the United States that were funded last year by DARPA, the Pentagon research agency, to design and build stimulators that could influence cognition by constantly recording brain function and zapping particular brain areas with low doses of electricity (see “Military Funds Brain-Computer Interfaces to Control Feelings”).
The Penn team, led by cognitive neuroscientist Michael Kahana, has already begun analyzing brain recordings from patients with severe epilepsy. As part of their treatment, these patients receive a small mesh of electrodes under their skulls, which they wear for two to seven weeks. The electrodes collect EEG recordings that are used to calculate where in their brains their seizures are originating, in preparation for surgery to remove the malfunctioning tissue.
While they undergo this treatment, some patients are also volunteering to let Kahana study them as they play memory games on a computer. The EEG electrodes record the average electrical activity of tens of thousands of neurons at once; Kahana says some of the brain waves measured this way are correlated with memory function.
