Continuous Theta Rhythm During Spatial Working Memory Task In Rodent Models Of Streptozotocin-Induced Type 2 Diabetes, Stephanie Hernandez, Ryan A. Wirt, James M. Hyman

McNair Poster Presentations

Alzheimer’s disease is a neurodegenerative disorder altering memory loss thought to be due to neuropathological symptoms such as the buildup of beta amyloid plaques (Ab) and neurofibrillary tangles (NFT). The etiology of Alzheimer’s is still unknown; however, potential risk factors such as diabetes may lead to its development. The most common form of diabetes is type 2 diabetes known for persistent insulin resistance leading to a state of hyperglycemia. Insulin resistance has been shown to affect cognitive abilities such as learning, memory and also alters synaptic plasticity. Neural connections between the hippocampus (HC) and anterior cingulate cortex (ACC) are known …

Decoding The Neural Circuitry Of Reward Behavior, Ernesto H. Bedoy, James M. Hyman

McNair Poster Presentations

Classical conditioning demonstrates that rewards can be used to train behavior by pairing a stimulus, known as a prompt, with reinforced behavior. At a neuronal level, this association strengthens the connections between the neurons involved, making communication easier the next time. Enhanced communication is identified with learning, allowing an organism to anticipate a reward with a prompt so that it can perform the desired behavior to successfully obtain the reward (Noonan et al., 2011). In this study, we created a computational model to represent a neural circuit with synaptic plasticity during reward, no-reward and anticipation states. Our results confirmed our …

Examining The Relationship Between Emotion Perception And Bullying: A Proposal, Marielle Leo, Kimberly A. Barchard

McNair Poster Presentations

Bullying and aggressive behaviors have adverse effects on many children. Violent behavior among children occurs most commonly in the school setting and may lead to negative emotional outcomes later in life (Kub & Feldman, 2015). According to a study conducted by Baroncelli et al. (2014), boys who have been found to be high in aggression have a difficult time perceiving relevant social cues such as fear and anger. However, boys were prone to frequently identify happiness and fear in faces when a different emotion was expressed. For girls, Baroncelli and colleagues did not find any significant relationships. The purpose of …

A Computational Perspective Of Schizophrenia, Ernesto H. Bedoy, Geoff Powell, Jefferson Kinney

McNair Poster Presentations

The etiology of schizophrenia remains largely elusive, thus dampening the effectiveness of current treatment strategies. Abnormal neural migration and neurogenesis in the hippocampus have been suggested to be involved in schizophrenia (Jakob & Beckmann, 1994). A few approaches, including computational modeling, have investigated schizophrenia as a network disorder. Computational modeling uses mathematics to predict the behavior of biological systems based on the input of a set of parameters collected from laboratory experiments. In this study, we constructed a computational model to explore the ramifications of additional PV neurons migrating to an aberrant location in the hippocampus and interfering with a …

Modulatory Effects Of Gaba(B) Receptor Facilitation In A Model Of Chronic Inflammation, Michael A. Langhardt, Jefferson Kinney

McNair Poster Presentations

Inflammation within the brain (neuroinflammation) has been associated with a number of neurodegenerative diseases, including Alzheimerʼs disease (AD) (Solito et al., 2012). Within the brain, inflammation is defined broadly as prolonged activation of the brainʼs immune cells, known as glial cells. Excessive activation of glial cells within the brains of AD patients is a hallmark of the disease, however the mechanism by which this contributes to disease pathology is relatively unclear (Jo et al., 2014). Recently, studies have shown that glial cells, known as astrocytes, are able to synthesize and release the inhibitory neurotransmitter GABA (Charles et al., 2003). Further, …

Correlates Of Compulsive Buying, Brittaney Benson-Townsend, N. Clayton Silver

McNair Poster Presentations

Compulsive buying is a chronic issue for shoppers exacerbated by a nation obsessed with consumption. To predict compulsive buying behavior, a survey was administered to 283 college students in southern Nevada. The results suggested that the compulsive buyer exhibits am ex­ternal consumer locus of control and purchases goods with the intent to increase social status or quell anxiety. Given that responsible financial behavior changes as a function of age, college students are particularly vulnerable to compulsive purchasing behavior, as it is exacerbated by irresponsible credit spending behaviors.

Evolution Of The Human Diet: What We Can Learn From Hunters And Gatherers, Kara Osborne, Alyssa Crittenden

McNair Poster Presentations

The study of hunter-gatherer populations around the world can greatly inform our understanding of the evolution of the human diet. Ethnographic research of modern hunter-gatherers has been used to infer the possible food consump­tion and acquisition patterns of our ancestors. Hunter-gatherers provide the in­formation necessary for the understanding of the past human diet, due to these populations living similar lifestyles in similar environments, therefore procuring similar foods.

The Hadza, a group of nomadic hunters and gatherers living in Tanzania, East Africa, are one of the primary populations that nutritional anthropologists study to infer what possible foods our ancestors acquired and …

Which Data Checking Method Is More Accurate?, Sarah Cobb, Kimberly A. Barchard

McNair Poster Presentations

Researchers use multiple methods for data checking. Each method can help identify and fix errors that were introduced during the data entry process. Fixing the errors that were introduced during the data entry process increases the accuracy of the research results. Accuracy is impor­tant because if a researcher publishes inaccurate results other researchers would not be able to replicate those results and draw the same conclusions. The purpose of this study is to compare the accuracy of four different data checking methods: double entry with one person, double en­try with two people, visual checking, and solo read aloud. So far, …
