Well, our TBI minds do tend to wander... lol

By regulating temperature, do you just mean feeling hot and/or cold - or do you mean your actual measured body temperature is fluctuating?

Feeling HOT... sweating buckets...normal body temp...

Sounds like hormone imbalances to me.

I was having the worst hot flashes before the HRT and I'm unusually very sensitive to hot and cold and even temperature changes since the accident I was in...

The brain does have stem cells and it does regenerate. Yours is a long-outdated view. Google "neurogenesis". ;-)

brain cells are generated extremely slowly in adulthood and only for certain functions. That is why a liver can regrow so much. The brain has very limited capacity to create new cells or I think perhaps a number of us wouldn't need o be on this board anymore

Is it all in our heads? Nope!! Well, our brains are in our heads but you know what I mean.

When I look back I can see I was severely impaired yet my Dr was dismissing it, I was in trouble, the way my brain was working or rather not working properly was huge.

I would even say to another Dr I was "okay" when clearly I wasn't, that just came out as I realize now I couldn't get the right words out.

People said I looked like a deer in a headlight, I'm amazed some light eventually came through considering the awful "care" I was getting.

Hockey: Thank God you survived that terrible accident, a true miracle

Yep, and only in the olfactory bulb and hippocampus according the latest research I've seen. Neurogenesis in the hippocampus may give hope for improved memory, but as you point out this happens slowly.

thanks for the extra info. I wonder, even if they could be created on a large scale, what about the damaged ones? the damage to my thalamus causes all kinds of autonomic problems. Wouldn't those old cells have to be disposed of as well as new ones being created.

And for a function like sleep, wouldn't the different brain parts have to learn how to communicate with each other correctly?

I guess that's why some say to focus on dealing with the symptoms if you're an old timer. New timers still have time to be great again.

Is there any stem cell research going on?

I'm not a neuroscientist but as I understand it, neuroplasticity more involves reestablishing neural pathways and connections that it does generating new neurons. So the connections bypass the damaged ones and reestablish new ones.

Some interesting discussions and fascinating case studies are in the book "The Brain that Changes Itself" by Norman Doidge, M.D.
