Use the labels in the right column to find what you want. Or you can go thru them one by one, there are only 29,294 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 neuronsthatDIEeach day because there areNOeffective 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.

Functional organization of human sensorimotor cortex for speech articulation
Speaking is one of the most complex actions that we perform,
but nearly all of us learn to do it effortlessly. Production of fluent
speech requires the precise, coordinated movement of multiple
articulators (for example, the lips, jaw, tongue and larynx) over rapid
time scales. Here we used high-resolution, multi-electrode cortical
recordings during the production of consonant-vowel syllables to
determine the organization of speech sensorimotor cortex in humans. We
found speech-articulator representations that are arranged
somatotopically on ventral pre- and post-central gyri, and that
partially overlap at individual electrodes. These representations were
coordinated temporally as sequences during syllable production. Spatial
patterns of cortical activity showed an emergent, population-level
representation, which was organized by phonetic features. Over tens of
milliseconds, the spatial patterns transitioned between distinct
representations for different consonants and vowels. These results
reveal the dynamic organization of speech sensorimotor cortex during the
generation of multi-articulator movements that underlies our ability to
speak.
