Recovery From Visual Dysfunction Following Mild Traumatic Brain Injury Is Associated With Adaptive Reorganization Of Retinal Inputs To Lateral Geniculate Nucleus In The Mouse Model Utilizing Central Fluid Percussion Injury., Vishal C. Patel
Theses and Dissertations
Traumatic brain injury (TBI) is a leading cause of morbidity and mortality nationwide. Prevalence of mild TBI (mTBI) vastly outnumbers more severe forms however the associated morbidity has only recently gained public attention. Visual dysfunction is a significant component of mTBI associated morbidity with recovery of function linked with improvement in global outcomes. Examination of sensory and motor pathways in other brain injury paradigms support that recovery is largely dependent on adaptive plasticity of remaining connections. Current examinations of visual function recovery following mTBI is limited to identifying evidence for recovery and objective evidence for adaptive plasticity is limited. Therefore, …

The Role Of Kisspeptin And Kndy Cells In The Reproductive Neuroendocrine System, Christina M. Merkley

The gonadotropin-releasing hormone (GnRH) neurons in the hypothalamus represent the final common output in the central control of reproduction. GnRH secretion is modulated indirectly by steroid feedback action of gonadal steroids on afferent interneurons. In recent years, the neuropeptide, kisspeptin, has emerged as a key mediator of steroid feedback onto GnRH neurons and the reproductive system. Kisspeptin neurons located in the preoptic area (POA) mediate estradiol (E2) positive feedback leading to the preovulatory surge, and kisspeptin cells in the arcuate nucleus (ARC) have been shown to mediate the negative feedback actions of E2 on pulsatile GnRH secretion. ARC kisspeptin neurons …
