Something our researchers should use to determine how a next door neuron goes to help its neighbor with a task. That understanding of neuroplasticity could make it repeatable within understood parameters.

The researchers demonstrated
the first application of their devices in optogenetics, a new area of
neuroscience that uses light to stimulate targeted neural pathways in
the brain. The procedure involves genetically programming specific
neurons to respond to light. Optogenetics allows researchers to study
precise brain functions in isolation in ways that are impossible with
electrical stimulation, which affects neurons throughout a broad area,
or with drugs, which saturate the whole brain.
Optogenetics experiments with mice illustrate the ability to
train complex behaviors without physical reward, and to alleviate
certain anxiety responses. Yet fundamental insights into the structure
and function of the brain that emerge from such studies could have
implications for treatment of Alzheimer’s, Parkinson’s, depression,
anxiety and other neurological disorders.
While a number of important neural pathways now can be studied by
optogenetics, researchers continue to struggle with the engineering
challenge of delivering light to precise regions deep within the brain.
The most widely used methods tether the animals to lasers with
fiber-optic cables embedded in the skull and brain – an invasive
procedure that also limits movements, affects natural behaviors and
prevents study of social interactions.
The newly developed technologies bypass these limitations with
specially designed powerful LEDs – among the world’s smallest, with
sizes comparable to single cells – that are injected into the brain to
provide direct illumination and precise control. The devices are printed
onto the tip end of a thin, flexible plastic ribbon – thinner than a
human hair and narrower than the eye of a needle – that can insert deep
into the brain with very little stress to tissue.

Use the labels in the right column to find what you want. Or you can go thru them one by one, there are only 29,112 posts. Searching is done in the search box in upper left corner. I blog on anything to do with stroke.DO NOT DO ANYTHING SUGGESTED HERE AS I AM NOT MEDICALLY TRAINED, YOUR DOCTOR IS, LISTEN TO THEM. BUT I BET THEY DON'T KNOW HOW TO GET YOU 100% RECOVERED. I DON'T EITHER, BUT HAVE PLENTY OF QUESTIONS FOR YOUR DOCTOR TO ANSWER.
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.
