Inter-Rater Reliablility Of Sharp Wave Ripple Detection In Recently Trained Experts, Orlando Montiel, Gage Pompa, Yader Gomez, Talha Soluoko

Undergraduate Research Symposium Posters

Sharp wave ripples (SWR) are a brain phenomenon that originate in the hippocampus, a region crucial for memory and learning. These events occur during periods of rest or slow-wave sleep and are characterized by fast oscillatory bursts (150-250Hz) and are thought to be important for the brain to consolidate memory. SWR are believed to facilitate the transfer of information from the hippocampus to the cortex, strengthening synaptic connections & enabling long-term memory storage. Accurate detection & assessment of SWRs is essential for advancing how the brain processes and stores information.

This study examines the accuracy/consistency of SWR image selection and …

The Effects Of Divides Attention On Long-Term Memory For Natualistic Stimuli, Gaia Steinberg, Jackson S. Pelzner, Rhiannon N. Soriano Smith, Colleen M. Parks

Undergraduate Research Symposium Posters

The ability to identify previously experienced events is a fundamental aspect of memory. This study investigates recognition memory using naturalistic stimuli, specifically news headlines, to explore both controlled (recollection) and automatic (familiarity) memory processes. Most recognition memory experiments rely on simplistic stimuli like words or pictures, but we aim to extend these theories by using more complex, naturalistic materials (news headlines). Participants completed recognition tasks with both headlines and pictures to establish baseline differences between these stimuli types. The order of presentation between stimulus types was randomized between pictures or headlines first. They were assigned to either full or divided …

Exploring Modality Differences In Recognition Memory: Repetition Effects On Recollection And Familiarity, Ivanesa Velikova, Kevin Mohawk, Colleen Parks

Undergraduate Research Symposium Posters

Research has shown that memory for visual objects tends to be superior compared to memory for auditory objects. The present study aimed to investigate the underlying mechanisms of why recognition memory tends to be better for visual information. Recognition memory relies on two processes, recollection and familiarity. Recollection involves retrieving contextual details of a memory while familiarity is simply a feeling that something has been encountered before. We investigated recollection and familiarity in the two modalities by having participants lean a list of auditory objects (e.g., dog barking) and visual objects (e.g., picture of a lion) under full attention (FA) …

Comparing Forgetting Rates Between Item And Relational Memories, Lex De Asis, Rhiannon N. Soriano Smith, Colleen M. Parks

Undergraduate Research Symposium Posters

Forgetting is an everyday occurrence where an idea that could be recalled successfully is no longer able to be retrieved (Tulving, 1974). Multiple theories suggest how forgetting occurs, such as the decay theory, which suggests that memories are gradually forgotten over time, and the interference theory, in which forgetting occurs because of competing information. Additionally, there are two newer theories which both predict that item representations should be forgotten because of interference and mnemonic discrimination should be forgotten due to decay: the memory system-dependent forgetting hypothesis (Hardt, Nader, & Nadel, 2013), and the representation theory of forgetting (Sadeh et al., …

The Characterization Of Cooperative String-Pullung Behavior In Rats After Exposure To Space Flight Stressors, Teresa L. Garcia, Nuhamine A. Moges, Sierra Ordonez, Nicole M. Attallah, D. H. Rodgers, A. Adhikari, K. D. Omengan, D. Lloyd, S. L. Gleed, A. A. Blackwell

Undergraduate Research Symposium Posters

Astronauts work cooperatively to complete tasks on missions through deep space where they will experience stressors, including radiation and sleep fragmentation, that may impair performance. Animals work together to achieve a common goal during cooperative tasks using string-pulling behaviors. While string-pulling behavior has revealed deficits in rat sensorimotor function after exposure to space flight stressors, it has yet to be determined if rats will engage in cooperative string-pulling or if these stressors will influence cooperation. Thus, to explore how space flight stressors impact cooperative behavior, female Wistar rats were exposed to either sham (n = 8) or 10 centi-grays of …

Effects Of Low Dose Exposure To Radiation And Sleep Fragmentation On Discrimination In String-Pulling Behavior With Female Rats, Jonathan F. Cortez, Diana Lloyd, T. L. Garcia, A. Adhikari, N. M. Attallah, N. Moges, D. H. Rodgers, K. S. Dhede, K. D. Omengan, A. A. Blackwell

Undergraduate Research Symposium Posters

Astronauts will face harmful stressors, such as galactic cosmic radiation (GCR) and sleep fragmentation (SF), on a three-year space flight mission to Mars and back. Astronauts perform skilled reach-to-grasp behaviors on these missions, including interacting with controls to navigate the spacecraft. Recent work has shown that GCR and SF disrupt skilled reach-to-grasp behavior in rodent models; however, the underlying nature of these deficits is unknown. To determine if tactile sensation and proprioceptive feedback contribute to these impairments, this study evaluated the effects of radiation and SF exposure on memory and sensorimotor discrimination in a rodent model. Twenty-one outbred Wistar, retired …

Existing literature suggests that infection-specific mechanisms may play a significant role in the onset and progression of dementia, as opposed to the broader phenomenon of systemic inflammation. In addition, 3-hydroxy-3-methylglutaryl (HMG)-coenzyme A (CoA) reductase inhibitors have been proposed as a potential therapeutic approach for sepsis, given their anti-inflammatory and antioxidant properties. We investigated the neuroprotective effect of an HMG-CoA reductase inhibitor (simvastatin) by analyzing neurodegenerative markers, mitochondrial respiration, and neuronal tracing in the prefrontal cortex (PFC) and thalamic nucleus reuniens (RE) of sepsis survivor animals. Adult Wistar rats were subjected to sepsis by cecal ligation and puncture or left non-manipulated. …

The Challenges Of Co-Developing Climate-Smart Strategies, Practices, And Technologies Among Research And Extension Teams, Michelle R. Worosz, Hannah Stewart, Mckayla Robinette, Brenda Ortiz, Rishi Prasad, Audrey Gambel, Leah Duzy

Journal of Extension

With climate-smart agriculture as the context, we explore one aspect of transdisciplinarity, the co-development of knowledge (CDK). Challenges were identified via matrix coding and word frequency queries of field day, meeting, and interview transcripts. Focusing on the Research-Extension team, we found they highly value collaboration and participatory-based projects, but developing trust-based relationships, enhancing long-term stakeholder investment, and understanding both team and stakeholder capacity was difficult. This paper informs transdisciplinary projects aimed at climate adaptation by illustrating the need for Research-Extension teams to take incremental steps towards CDK, to engage stakeholders before program planning, and to increase both interaction and reflexivity.

Journal of Extension

Face-to-face cooking programs can positively impact food choices, fruit and vegetable intake, and cooking self-efficacy; however, little is known about virtual cooking programs. We studied the perceived acceptability of the virtual SWITCH Cooking School (SCS). Four monthly cooking classes were offered for each participating school. Classes included nutrition education, food safety, and cooking demonstrations. Feedback was collected through post-class surveys and focus groups with parent/guardian and youth participants. Families valued the convenience of the virtual delivery and were interested in participating again. Future considerations for the SCS include incorporating additional variety of culinary skills and modifying registration methods.

Who Cares For The Caregiver? Exploring Extension’S Role In Informal Caregiving Support, Mckenzie R. Tuttle, Erin L. Martinez, Aimee Fox

Journal of Extension

Family caregivers provide invaluable service by taking on the responsibility of caring for older adults in the United States. With a growing aging population, the need for family caregivers and demands on their time and resources will continue to increase. Although a variety of caregiving resources and support services exist, family caregivers often lack the awareness, time, transportation, or financial resources to connect to services. There is a critical need to address the barriers that prevent caregivers from accessing services. In this commentary, we highlight barriers and make recommendations for improving conversations, research, and practice to meet this growing problem.

Growers’ Perceptions And Strategies To Mitigate Spring Frost Injury In Grapevines, Vinicius Cervilieri, Imed Dami, Guilherme Signorini

Journal of Extension

Uncertain weather patterns raise concerns about frequent spring frosts and injury in grapevines. This article quantifies growers’ perceptions of susceptibility to spring frosts and examines their satisfaction with existing mitigation strategies. Departing from a survey with grape growers, results show that over 80% of sampled growers have experienced damage due to frosts. Over-vine sprinklers, proper site selection, and adoption of late budding cultivars are the practices with the highest satisfaction levels. None of the strategies examined reached the highest satisfaction score. In addition, 61% of respondents showed interest in sprayable products to delay budbreak and circumvent grapevine damage.

Analysis Of The Integration Of Race And Cultural Concordant Doulas Into The Birth Experience Of African American Women, Cherissa Garcia

Best Integrated Writing

Garcia's study looks at how integrating race and cultural-concordant doulas into the birth experience of African American women would impact outcomes. She found similar studies that provided strong evidence to support doula integration. However, most did not select study populations that appropriately reflected the African American women at increased risk of poor outcomes. As a result, Garcia designed a study that looked at race and cultural concordance between doulas and patients from a wide range of SES backgrounds and varying degrees of pregnancy risk.
