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:

Jagged1 is necessary for postnatal and adult neurogenesis in the dentate gyrus

How is your doctor ensuring you get Jagged1 and notch proliferation to help your neurogenesis? Do they have any idea what it is? Or why it's important to your recovery?

Jagged1 is not necessary for embryonic dentate gyrus formation
Jagged1 is required for postnatal and adult neurogenesis in the dentate gyrus
Notch/Jagged1 is required for progenitor proliferation and maintenance


Understanding the mechanisms that control the maintenance of neural stem cells is crucial for the study of neurogenesis. In the brain, granule cell neurogenesis occurs during development and adulthood, and the generation of new neurons in the adult subgranular zone of the dentate gyrus contributes to learning. Notch signaling plays an important role during postnatal and adult subgranular zone neurogenesis, and it has been suggested as a potential candidate to couple cell proliferation with stem cell maintenance. Here we show that conditional inactivation of Jagged1 affects neural stem cell maintenance and proliferation during postnatal and adult neurogenesis of the subgranular zone. As a result, granule cell production is severely impaired. Our results provide additional support to the proposal that Notch/Jagged1 activity is required for neural stem cell maintenance during granule cell neurogenesis and suggest a link between maintenance and proliferation of these cells during the early stages of neurogenesis.
