Neural Correlates Of Social Pain In Psychological Disorders: Implications For Educational Settings, Skye E. Johnson
Neural Correlates Of Social Pain In Psychological Disorders: Implications For Educational Settings, Skye E. Johnson
Honors Projects
Pain has long been defined as a multidimensional construct; in past research, not only have the physical and sensory aspects of pain been investigated, but also the cognitive and emotional aspects, which include the experience of social pain. This experience is generally accepted to be very distressing and can have adverse effects on one's mental health, especially for those with neurological disorders. In my paper, I examine the effects of social pain on brain activity in individuals with autism spectrum disorder (ASD) and borderline personality disorder (BPD) as compared to those who are neurotypical. This research finds that while neurotypical …

Biological System Energy Algorithm Reflected In Sub-System Joint Work Distribution Movement Strategies: Influence Of Strength And Eccentric Loading, Jeffrey M. Mcbride, Sophia Nimphius
Research outputs 2014 to 2021
© 2020, The Author(s). To better understand and define energy algorithms during physical activity as it relates to strength and movement strategy of the hip, knee and ankle, a model of increasing eccentric load was implemented in the current investigation utilizing a countermovement jump and a series of drop jumps from different heights (15, 30, 45, 60, 75 cm). Twenty-one participants were grouped by sex (men, n = 9; women, n = 12) and muscle strength (higher strength, n = 7; moderate strength, n = 7; lower strength, n = 7) as determined by a maximal squat test. Force plates …
Intraoperative Management Of Lumbar Cerebrospinal Fluid Drains: A Reference Tool, Victoria Shink
Intraoperative Management Of Lumbar Cerebrospinal Fluid Drains: A Reference Tool, Victoria Shink
College of Science and Health Theses and Dissertations
Lumbar cerebrospinal fluid (CSF) drains are invasive interventional devices implemented for patients suffering from neurosurgical and complex aortic conditions. CSF drain management can be an infrequent task for anesthesia providers. Infrequent exposure can lead to inadvertent mismanagement leaving the patient vulnerable to increased morbidity and mortality. The purpose of this study was to develop a reference tool for basic intraoperative management of lumbar CSF drains and determine if CRNA and SRNA knowledge was improved with its use. This study utilized a pre-test/post-test design. The pre-test revealed significant knowledge gaps in content crucial for safe drain manipulation and management. Improvement in …
Linking Brain Structure To Function To Value-Based Choice, Josiah Leong
Linking Brain Structure To Function To Value-Based Choice, Josiah Leong
Publications and Presentations
What humans choose and how their brains make choices are central questions in psychology and neuroscience. Neuroimaging research is advancing models of functional brain activity that not only correlate with, but also predict, value-based choices in humans. Physiological research in animals suggests that monosynaptic axons structurally connect the brain circuits predictive of choice. However, similar structural connections have only recently been characterized in humans, and researchers are now starting to explore links from structural brain connections to functional brain activity to behavioral choice. In this lecture, Leong presents recent findings that link multimodal neuroimaging measurements to individual differences in value-based …
Evaluation Of Aging And Genetic Mutation Variants On Tauopathy, Amber M. Tetlow
Evaluation Of Aging And Genetic Mutation Variants On Tauopathy, Amber M. Tetlow
USF Tampa Graduate Theses and Dissertations
Alzheimer’s disease (AD) is characterized by amyloid β plaques and neurofibrillary tau tangles (NFTs). While research has demonstrated amyloid pathology occurs prior to tau pathology, or tauopathy, tau has proven to be more toxic. Tauopathy is associated with cognitive declines and neurodegeneration. These findings have highlighted the importance of further understanding tauopathy. In the progression of tauopathy, there is an observable immune response that can be measured by glial cells such as microglia. Activated microglia are known to exacerbate tauopathy rather than reducing the pathology. Research has indicated that with increased age there is an increased risk for AD-related tauopathy …

Modulation Of Sleep-Courtship Balance By Nutritional Status In Drosophila, José M Duhart, Victoria Baccini, Yanan Zhang, Daniel R Machado, Kyunghee Koh
Modulation Of Sleep-Courtship Balance By Nutritional Status In Drosophila, José M Duhart, Victoria Baccini, Yanan Zhang, Daniel R Machado, Kyunghee Koh
Farber Institute for Neuroscience Faculty Papers
Sleep is essential but incompatible with other behaviors, and thus sleep drive competes with other motivations. We previously showed Drosophila males balance sleep and courtship via octopaminergic neurons that act upstream of courtship-regulating P1 neurons (Machado et al., 2017). Here, we show nutrition modulates the sleep-courtship balance and identify sleep-regulatory neurons downstream of P1 neurons. Yeast-deprived males exhibited attenuated female-induced nighttime sleep loss yet normal daytime courtship, which suggests male flies consider nutritional status in deciding whether the potential benefit of pursuing female partners outweighs the cost of losing sleep. Trans-synaptic tracing and calcium imaging identified dopaminergic neurons projecting to …
The Reliability And Heritability Of Cortical Folds And Their Genetic Correlations Across Hemispheres, Fabrizio Pizzagalli, Guillaume Auzias, Qifan Yang, Samuel R. Mathias, Joshua Faskowitz, Joshua D. Boyd, Armand Amini, Denis Rivière, Katie L. Mcmahon, John Blangero

Cortical folds help drive the parcellation of the human cortex into functionally specific regions. Variations in the length, depth, width, and surface area of these sulcal landmarks have been associated with disease, and may be genetically mediated. Before estimating the heritability of sulcal variation, the extent to which these metrics can be reliably extracted from in-vivo MRI must be established. Using four independent test-retest datasets, we found high reliability across the brain (intraclass correlation interquartile range: 0.65–0.85). Heritability estimates were derived for three family-based cohorts using variance components analysis and pooled (total N > 3000); the overall sulcal heritability pattern was …

We investigated how the attenuation of pain with cognitive interventions affects brain connectivity using neuroimaging and a whole brain novel analysis approach. While receiving tonic cold pain, 20 healthy participants performed three different pain attenuation strategies during simultaneous collection of functional imaging data at seven tesla. Participants were asked to rate their pain after each trial. We related the trial-by-trial variability of the attenuation performance to the trial-by-trial functional connectivity strength change of brain data. Across all conditions, we found that a higher performance of pain attenuation was predominantly associated with higher functional connectivity. Of note, we observed an association …
Analysis Of Newspaper Coverage Of Psilocybin From January 1, 1989 To December 31, 2019, Dax Oliver
Analysis Of Newspaper Coverage Of Psilocybin From January 1, 1989 To December 31, 2019, Dax Oliver
Dissertations, Theses, and Capstone Projects
Psilocybin is a chemical compound that has received a lot of attention from medical researchers in recent years. However, this research is not merely a medical issue but a social and political one as well. In the 1960s, psilocybin and other psychedelic compounds were widely ingested outside of clinical settings. This alarmed some of the American public, resulting in severe legal restrictions on psilocybin use and research.
Today, many psilocybin advocates hope that it will avoid the negative public sentiment of the 1960s. To help gauge public sentiment about other psychoactive compounds, some studies have examined newspaper coverage, but there …

Chronic pain and the opioid epidemic need early, upstream interventions to aim at meaningful downstream behavioral changes. A recent pain neuroscience education (PNE) program was developed and tested for middle-school students to increase pain knowledge and promote healthier beliefs regarding pain. In this study, 668 seventh-grade middle-school students either received a PNE lecture (n = 220); usual curriculum school pain education (UC) (n = 198) or PNE followed by two booster (PNEBoost) sessions (n = 250). Prior to, immediately after and at six-month follow-up, pain knowledge and fear of physical activity was measured. Six months after the initial intervention school, …

Predator Odor Stress On Stress And Metabolic Endocrine, Morgan Block, Katie Wilk
Predator Odor Stress On Stress And Metabolic Endocrine, Morgan Block, Katie Wilk
Student Scholars Day Posters
It is known that the brain and gut ‘talk’ to each other, which is important for both physical and mental health as shown by associations between metabolic syndrome and mental illness in humans. Neuropeptides found in both the brain and gut are active in this communication and may mediate links between stress, metabolism, and psychopathology. This study aims to determine whether single exposure to predator odor is able to produce long-term changes in the endocrine system as measured by plasma concentrations of the “stress hormone” corticosterone and “hunger hormone” ghrelin. Male and female mice were exposed to one hour of …

Astronauts on interplanetary missions - such as to Mars - will be exposed to space radiation, a spectrum of highly-charged, fast-moving particles that includes 56Fe and 28Si. Earth-based preclinical studies show space radiation decreases rodent performance in low- and some high-level cognitive tasks. Given astronaut use of touchscreen platforms during training and space flight and given the ability of rodent touchscreen tasks to assess functional integrity of brain circuits and multiple cognitive domains in a non-aversive way, here we exposed 6-month-old C57BL/6J male mice to whole-body space radiation and subsequently assessed them on a touchscreen battery. Relative to …
Mechanisms Of Value-Biased Prioritization In Fast Sensorimotor Decision Making, Kivilcim Afacan-Seref
Mechanisms Of Value-Biased Prioritization In Fast Sensorimotor Decision Making, Kivilcim Afacan-Seref
Dissertations and Theses
In dynamic environments, split-second sensorimotor decisions must be prioritized according to potential payoffs to maximize overall rewards. The impact of relative value on deliberative perceptual judgments has been examined extensively, but relatively little is known about value-biasing mechanisms in the common situation where physical evidence is strong but the time to act is severely limited. This research examines the behavioral and electrophysiological indices of how value biases split-second perceptual decisions and the possible mechanisms underlying the process. In prominent decision models, a noisy but statistically stationary representation of sensory evidence is integrated over time to an action-triggering bound, and value-biases …
Mood Effects And Individual Differences On Reappraisal And Distraction: An Erp Study Of The Sensitivity Of Emotion Regulation Strategies, Elsa Mastico
All Master's Theses
The present research evaluated the effect of mood and individual differences on the regulatory process of emotions by using a regulation task with negative and neutral images to assess reappraisal and distraction ability. Specifically, this research evaluated the average amplitude of the latent positive potential (latent positivity, LPP) brainwave linked to distraction and reappraisal using an ERP analysis. In addition, the current study compared the modulation of the LPP to the self-reported mood of the participants and their individual differences in regulation ability through scores of a self-report emotion regulation questionnaire. The latent positive potentials from an emotion regulation task …
Assessing Morphology Of Iprgcs After Traumatic Brain Injury, Brian Foresi, Matt Smith
Assessing Morphology Of Iprgcs After Traumatic Brain Injury, Brian Foresi, Matt Smith
Williams Honors College, Honors Research Projects
ipRGCs are retinal ganglion cells that project to visual processing centers of the brain for nonimage forming visual functions. The relation of ipRGCs to tramatic brain injury (TBI) is emerging as data has been published describing ipRGC functional changes in TBI affected military veterans. Major symptomologies of concussions, a mild form of TBI, also overlap with the function governed by sites in the brain with major ipRGC projection percentages. Assesing if a morphological change is occuring in the ipRGCs after a TBI could support the idea of a pathological mechanism of the injury. This study could also indicate further relevance …

Neuroanatomy Of The Blackspotted Rockskipper, Entomacrodus Striatus, Pooja Dayal
Williams Honors College, Honors Research Projects
Here I characterized the central neuroanatomy of the Blackspotted Rockskipper, Entomacrodus striatus, native to French Polynesia. The neuroanatomy of E. striatus has not been studied prior to this paper. I used several histology and antibody staining techniques to accomplish this, including Crystal Violet, immunohistochemistry, immunofluorescence, and Bielschowsky’s Silver Nitrate staining. This paper describes the most successful techniques used, identifies major structures in the species’ neuroanatomy, and also explains why studying E. striatus is important in the future of vertebrate research.
Melanopsin-Expressing Retinal Ganglion Cells In Control Vs. Glaucomatous Retinas, Edward Hamad
Melanopsin-Expressing Retinal Ganglion Cells In Control Vs. Glaucomatous Retinas, Edward Hamad
Williams Honors College, Honors Research Projects
Glaucoma is a common cause of vision loss worldwide and has a large scope of symptoms, ranging from pupillary reflex defects to sleep disorders. These issues can be explained partially by a recently found subtype of retinal ganglion cells that express melanopsin, denoted melanopsin-expressing retinal ganglion cells or mRGCs for short. These cells function primarily as photoreceptors in the non-image forming pathway, but can receive input from rods and cones. Since mRGCs play a role in the pupillary reflex and regulation of the sleep-wake cycle, I investigated if glaucoma leads to the degeneration of these cells in a mouse model …

Research outputs 2014 to 2021
Our research team was asked to consider the relationship of the neuroscience of sensorimotor control to the language of emotions and feelings. Actions are the principal means for the communication of emotions and feelings in both humans and other animals, and the allostatic mechanisms controlling action also apply to the regulation of emotional states by the self and others. We consider how motor control of hierarchically organised, feedback-based, goal-directed action has evolved in humans, within a context of consciousness, appraisal and cultural learning, to serve emotions and feelings. In our linguistic analysis, we found that many emotion and feelings words …
Spinal Motor Neuron Excitability And Balance Control Changes Following Downslope Walking, Nikki Aitcheson-Huehn
Spinal Motor Neuron Excitability And Balance Control Changes Following Downslope Walking, Nikki Aitcheson-Huehn
Theses and Dissertations (Comprehensive)
Downslope walking (DSW) has been proposed as a rehabilitation tool for people with Multiple Sclerosis (PwMS) although there are mixed findings in young adults (YA) regarding the balance control changes, despite both populations experiencing depressed spinal motor neuron (MN) pool excitability. Our aim was to determine whether YAs could demonstrate improved balance control in conjunction with SOL H reflex depression (estimate of spinal MN excitability) following DSW. We also aimed to determine whether reciprocal inhibition was a potential mechanism for H reflex depression via conditioned SOL H reflexes. Thirty young adults (23±1.4y, 6 males) were assigned to 30-minutes of DSW …
