    Do you think neurons can regenerate? Traditionally I've heard that they cannot, but it sounds like some people are questioning this or do you think they are talking about reorganization not regeneration?

    Parts of the brain normally specialized to one function can assume other duties. That's reorganization.

    If you mean individual neurons, what do you mean "regeneration"?

    The ability of a neuron to grow and replace another damaged one. So growth and reorganization, as opposed to just reorganization.

    One neuron can't do simultaneous double duty, as in twice the size serving twice the function. It's a single "quantum".

    A neuron can branch out so that it stimulates more neighbours. Because unstimulated neurons atrophy and eventually die, this could be seen as "growing more neurons" though it's really just using/preserving what you have.

    You can grow new neurons but the rate is less than attrition from aging.



    Quantity isn't necessarily quality. We're built with plenty of surplus brain; we lose at birth, in early childhood, and continue losing through adulthood. I disagree with the popular assumption that brains chock-a-block with lively neurons must be optimal. Voids are meaningful. How much information do you read from a solid white page?

    When axons have been cut due to spinal cord injury, they can be coaxed to regenerate if a combination of treatments is applied. (Oct 29 labslink.com research news) The chronically injured axon is not dead

    I think it was already shown in early 1900s that neurons can regenerate. Can't remember the name of the guy, but my friend read the articles. He was just looking at proliferation from histological sections.

    The areas he found with neuron regeneration corresponded exactly to the ones we know nowadays which have neuron regeneration.

    Isn't it more interesting to determine with facts whether neurons can regenerate instead of starting a poll on whether people think they can????

    Perhaps we could have a poll on which approach people would find more interesting.

    Golkarian - Look up neurogenesis and neuroplasticity. You will probably be able to find a lot of answers to your most basic questions with a quick review of those terms.

    I actually asked the same question to my pathology teacher last week, and he said that it was found out (though not proven) that neurons are able to replicate under certain stimuli. But it's quite a rare occurence.
