That has to be the case, at least in higher cortical areas (and maybe
throughout the NS), otherwise we couldn't learn anything. But I have a
very specific question. When neurons are active (fire action
potentials) they release neurotransmitters and neuromodulators of
various sorts. Some of these things must be responsible for inducing
plasticity -- rearrangements in the surrounding brain tissue. My
question is do *all* neurons produce whatever it is that induces
plasticity, or only some?
Thanks for the response.
