    “…FINDINGS: The pathology underlying the observed white-matter MRI changes was explored by performing immunohistochemistry for healthy axons and myelin. The presence of both healthy axons and myelin was reduced in the contralateral white-matter lesion. …”

    “…We identified Rtca, RNA 3′-terminal phosphate cyclase, as an inhibitor for axon regeneration. Removal of dRtca cell-autonomously enhanced axon regrowth in the Drosophila central nervous system, whereas its overexpression reduced axon regeneration in the periphery. …”

    “…There was a trend for those with greater impairment in gross motor function to have more abnormal axon properties. The findings indicate plasticity of motor axon properties far removed from the site of the lesion. …”

    “…The limited intrinsic regenerative response mounted by adult central nervous system (CNS) neurons is further hampered by astrogliosis, myelin debris and scar tissue that characterize the damaged CNS. Improved axon regeneration and recovery can be elicited by targeting extrinsic factors as well as by boosting neuron-intrinsic growth regulators. …”

    “…With this system we could detect [Ca(2+)](i) and [Na(+)](i) changes from single action potentials in axons and synaptically evoked signals in dendrites, both with submicron resolution and a good signal-to-noise ratio (S/N).…”
