Ventriclulomegaly, or the expansion of the ventricles in the brain, is a phenomenon associated with age and injury to the brain. The ependymal layer that encases the ventricles displays certain degrees of plasticity and regenerative ability due to its associated stem cell niche, the subventricular zone (SVZ). Previous research in the Conover Lab has shown that in the mouse, which maintains an actively proliferating SVZ into adulthood, there is an intact ependymal monolayer throughout normal aging, with maintained lateral ventricle size with some degree of stretching. In contrast, the human SVZ declines in proliferative capacity after infancy, and age-related changes …

Hypoxia-ischemia (HI) is low oxygenation to the brain paired with low blood supply that can disrupt normal patterns of brain development. HI injury is characterized by many long-term cognitive and behavioral deficits including working memory. Neuronal plasticity due to early sensory or learning experience has been suggested to facilitate recovery of function after neonatal brain injury. Plasticity is the ability for the nervous system, more specifically neurons, and their synapses to modify their function and morphology due to experiences, which in turn correlate with changes in behavior. The objective of the present study was to investigate the effects of neonatal …
