very interesting, too bad they didn't give a hint how they did it. i'd wager the ultimate challenge is promoting cellgrowth in vivo, no surgery required...


did you find it strange that brain cells have the capability to regenerate but normally don't use it? where's the evolutionary sense in that?

Maybe it's an evolutionary glitch, or something that hasan of and
on switch that gets turned off for the majority of life.

The "evolutionary sense" is that too many neural cells will quickly lead to empty synapses. This is the cause of nearly all chemical imbalance issues. The body would have no way of knowing how to mirror the connections amde prior to a massive injury, just as reconstructed muscle often heals differently than the pre-injury muscle.

OK, I have a question, in that case would it mean you'd have a different personality, or be a different person than before if the damage had been significant enough?

thanks for the links (especially the 2nd), i've heard of the X- /MRL- mice, iirc, their regenerative capabilites were introduced by accident and incurred serious immunologic side effects (which may or may not be related). i know that people are researching regenerative capabilities, yet look at the responses in this thread; bsl4 immediately summoned cancer to explain why we can't have regeneration, when we a) clearly have them, to a degree and b) stem cell therapy wouldn't work either if the reasoning was valid.
