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.

New approach uses silicon-based photonic probe to deliver light deep within brain tissues

So your doctor and researcher should now be able to stimulate deeper neurons using optogenetics.
http://www.news-medical.net/news/20161208/New-approach-uses-silicon-based-photonic-probe-to-deliver-light-deep-within-brain-tissues.aspx
The ability to stimulate neural circuits with very high precision light to control cells -- optogenetics -- is key to exciting advances in the study and mapping of the living brain. In the current state of the art, spatially patterned light projected via free-space optics stimulates small, transparent organisms and excites neurons within superficial layers of the cortex.
However, light scattering and absorption in neural tissue cause light penetration to be extremely short, making it impossible to employ free-space optical methods to probe brain regions deeper than about 2 mm.
In "Patterned photostimulation via visible-wavelength photonic probes for deep brain optogenetics," published today by SPIE, the international society for optics and photonics, in the journal Neurophotonics, principal author Eran Segev of professor Michael Roukes' group at Caltech, along with coauthors from Caltech, Baylor College of Medicine, and Stanford University, describe a solution. The article is available via open access.
Their approach combines nanophotonics and microelectromechanical systems (MEMS) in an implantable, ultra-narrow, silicon-based photonic probe to deliver light deep within brain tissues. This minimally invasive technique avoids major tissue displacement during implantation.
Using techniques of optogenetics, a protein in the brain serves as a sensory photoreceptor and can be controlled by specific wavelengths of light. These combined techniques provide a new approach to stimulation of brain circuits with remarkable resolution, enabling observation and control of individual neurons.
These breakthroughs present widespread and promising applications for the neuroscience and neuromedical research communities. From characterizing the role of specific neurons and identifying neural circuits responsible for behavior to enabling new methods of operant conditioning through reward-induced circuit activations, optogenetics has become a new path for neuroscientists seeking advances in research capabilities.
The article appears in a special section in Neurophotonics, Brain Mapping and Therapeutics, with Shouleh Nikzad, Jet Propulsion Laboratory, Caltech, serving as senior guest editor. The special section is part of an SPIE partnership with the Society for Brain Mapping and Therapeutics (SBMT), serving as a multidisciplinary approach for using advanced technology to solve neurological disorders and disease and to understand neuroscience. The effort was initiated during Nikzad's term as SBMT president in 2015.
David Boas of Massachusetts General Hospital, Harvard Medical School, is the editor-in-chief of Neurophotonics. Launched in 2014, Neurophotonics is published digitally in the SPIE Digital Library and in print. The journal covers advances in optical technology applicable to the study of the brain and their impact on basic and clinical neuroscience applications.
The SPIE Digital Library contains more than 458,000 articles from SPIE journals, proceedings, and books, with approximately 18,000 new research papers added each year. Abstracts are freely searchable, and a number of journal articles are published with open access.
