Neuronal Degeneration And Short-Term Memory Impairment After Tbi, Obiamaraije Igwe Nov 2017

Neuronal Degeneration And Short-Term Memory Impairment After Tbi, Obiamaraije Igwe

Traumatic brain injury (TBI) was associated with impaired short-term memory with causes of vehicle accidents and falls. Protein plaques containing fibrinogen (Fg), are associated with memory loss. After TBI, Fg in blood was higher than normal (>~2 mg/ml), which resulted in increased Fg in extravascular space. Therefore, Fg bonded to its endothelial receptor intercellular adhesion molecule-1 (ICAM-1). Fg then interacted with cellular prion protein (PrPC), which had a strong effect on the loss of memory and cognition. Mechanisms of Fg and PrPC complex formation and its functional implication are not known. This present study tested the level of Fg-PrPC …

Assessment Of Olfactory-Based Social Recognition: Designing A Paradigm For Marmosets, Stephanie Womack

UNO Student Research and Creative Activity Fair

Navigation of the social world depends largely on one’s responsiveness to social stimuli and information from a wide range of senses can be used to discriminate between individuals. Mammals use several sensory modes to communicate and respond to their surroundings, but olfaction is the dominant sense across most species. Chemosignals provide a wealth of information including sex, age, reproductive status, and individual identity. Currently, assessment of olfaction is largely limited to the habituation-dishabituation paradigm or the two-choice discrimination task used primarily in rodents. These paradigms are limited by their reliance on inherent reward of interaction with stimuli without providing additional …
