Injury Establishes Constitutive Μ-Opioid Receptor Activity Leading To Lasting Endogenous Analgesia And Dependence, Gregory F. Corder Jan 2013

Injury Establishes Constitutive Μ-Opioid Receptor Activity Leading To Lasting Endogenous Analgesia And Dependence, Gregory F. Corder

Theses and Dissertations--Physiology

Injury causes increased pain sensation in humans and animals but the mechanisms underlying the emergence of persistent pathological pain states, which arise in the absence of on-going physical damage, are unclear. Therefore, elucidating the physiological regulation of such intractable pain is of exceptional biomedical importance. It is well known that endogenous activation of µ-opioid receptors (MORs) provides relief from acute pain but the consequences of prolonged endogenous opioidergic signaling have not been considered. Here we test the hypothesis that the intrinsic mechanisms of MOR signaling promote pathological sensitization of pain circuits in the spinal cord. We found that tissue inflammation ...


Post-Traumatic Sleep Following Diffuse Traumatic Brain Injury, Rachel K. Rowe Jan 2013

Post-Traumatic Sleep Following Diffuse Traumatic Brain Injury, Rachel K. Rowe

Theses and Dissertations--Neuroscience

Traumatic brain injury (TBI) is a major cause of death and disability throughout the world with few pharmacological treatments available for individuals who suffer from neurological morbidities associated with TBI. Cellular and molecular pathological processes initiated at the time of injury develop into neurological impairments, with chronic sleep disorders (insomnia, hypersomnolence) being among the somatic, cognitive and emotional neurological impairments. Immediately post-injury, TBI patients report excessive daytime sleepiness, however, discordant opinions suggest that individuals should not be allowed to sleep or should be frequently awoken following brain injury. To provide adequate medical care, it is imperative to understand the role ...
