    Cells that fire together, wire together. Has anyone done much research on plasticity/neuroscience? I find the concept fascinating.

    NEUROPLASTICITY IS AAAAAWWWWWWEEEESOOOOOOOOOMMEEEE!
    Yes I have researched it a bit :3.

    It was shown that even if you are very old, and have had a stroke, as long as you work at it you can fully recover; something that has been thought impossible in the past as we were all told that the brain can't grow or regenerate at all past the age of 2.

    The synaptic connections between the dendrites and the axon of adjacent neurons supposedly cause memory and the ability to adjust those connections correlates to the ability to learn.

    Huh, I'd heard that the brain stops growing around 11-14, and after that a person is better at expounding upon what they learned to 'learn' (i.e., becomes a natural at) while their brain WAS still growing. Neural regeneration cases do seem to have cropped up, albeit ~very~ rarely and largely following serious physical trauma.

    Don't quite me verbatim, but that comes from years of sorta-kinda-following the subject here and there. One conservative at the office always tries to argue with me about it.

    So Long Term Potentiation (LTP) can explain many ritualistic or habitual activities that are formed with humans. The neuronal connections create associations between things, such as memory and action. So every time you recall a certain memory, it might naturally lead to a procedural memory of action which has become the natural response due to LTP.

    OCD has been overcome by redirecting thoughts/memories/feelings to actions different from that linked through LTP. This sort of redirection is referred to as Long Term Depression (not in the psychological sense) by ignoring and consciously choosing other action, over time the habitual urges lessen. OCD is more than that though, I can't remember the exact cause, but some part of the prefrontal cortex (I think) has an overactive pathway that causes high anxiety which would make that natural procedural association seem so urgent.
