I don't care about your use of big words and discussion/overview. Survivors want protocols for recovery. GET THERE! How the hell do we get stroke researchers to focus on the only reason for stroke research? 100% recovery for all. What stroke leaders do we need to convince that is the only goal?

Abstract
Adult
neurogenesis in the subventricular zone is a topic of intense research,
since it has vast implications for the fundamental understanding of the
neurobiology of the brain and its potential to being harnessed for
therapy in various neurological disorders. Investigation of adult
neurogenesis has been complicated by the difficulties with
characterization of neural stem cells in vivo. However, recent
single-cell transcriptomic studies provide more detailed information on
marker expression in neural stem cells and their neuronal lineage, which
hopefully will result in a more unified discussion. Regulation of the
multiple biological steps in adult neurogenesis comprises intrinsic
mechanisms as well as extrinsic factors which together orchestrate the
process. In this review, we describe the regulating factors and their
cellular sources in the physiological condition and provide an overview
of the regulating factors mediating stroke-induced stimulation of
neurogenesis in the subventricular zone. While there is ongoing debate
about the longevity of active post-natal neurogenesis in humans, the
subventricular zone has the capacity to upregulate neurogenesis in
response to ischemic stroke. Though, the stroke-induced neurogenesis in
humans does not seem to translate into adequate functional recovery,
which opens discussion about potential treatment strategies to harness
this neuroregenerative response. Various therapeutic approaches are
explored in preclinical and clinical studies to target endogenous
neurogenesis of which some are discussed in this review.
