Deans' stroke musings

Changing stroke rehab and research worldwide now.Time is Brain!Just think of all the trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 493 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:

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's quite disgusting that this information is not available from every stroke association and doctors group.
My back ground story is here:

Discovering the neural mechanisms of skill learning

I bet your doctor won't use this to update your stroke protocols. You'll have to figure this out on your own.
Most people can swing a hammer, but most people cannot swing said hammer with the fluid speed and precision of a master carpenter. The difference is thousands of hours of practice and the systematic organization of hundreds of thousands of the brain's neurons.
"Practice makes perfect, in a pretty literal sense. When we improve at a skill over time, it is presumably driven by coordinated changes in our brain's neural representation of how that movement should be completed," explains Steven Chase, assistant professor of Biomedical Engineering and the Center for Neural Basis of Cognition at Carnegie Mellon University. "Yet, the link between how our brain reorganizes its and how we learn a new skill is still largely unknown."
Chase was recently awarded the National Science Foundation (NSF) Faculty Early Career Development (CAREER) Award to discover the link between the neural reorganization and skill learning. With the award, one of the NSF's most prestigious awards in support of junior faculty, he will also research the behavioral factors that drive skill learning. Chase has been awarded an $800,000 five-year grant for his research.
An improved understanding of the science behind skill learning will have long-term impact on the clinical understanding of the progression of various motor control disorders, such as Parkinson's disease and stroke. His research may inform the design of targeted rehabilitation paradigms for those patient groups.
"You can imagine stroke as a sort of rewiring of the brain's system. Because parts of the brain are now dead, there are neurons that contribute completely differently to that circuit," explains Chase. "In stroke rehabilitation, the brain must learn to use those neurons in an appropriate way for this altered system. We want to understand how the brain does this learning."
A major challenge in studying skill learning is that most movements engage tens of thousands of neurons, and the link between any individual neuron and movement is not known. To overcome this problem, Chase and his lab will use a , a device that allows the brain to control a computer cursor using thought alone, and observe how neurons change when mastering control of the device. By using a brain-computer interface, Chase says the group can interpret how changes in combine to enable .
"Sometimes our brain actually requires us to rebuild a neural circuit in order to make what was previously impossible, possible," explains Chase. "With this award, we will go deep into that process and answer the question: 'how do you rebuild those neural circuits?'"
