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 …


Neural Correlates Of Social Pain In Psychological Disorders: Implications For Educational Settings, Skye E. Johnson Dec 2020

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 …


Linking Brain Structure To Function To Value-Based Choice, Josiah Leong Nov 2020

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 …


Modulation Of Sleep-Courtship Balance By Nutritional Status In Drosophila, José M Duhart, Victoria Baccini, Yanan Zhang, Daniel R Machado, Kyunghee Koh Oct 2020

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 Sep 2020

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 …

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 Apr 2020

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 …

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 …
