Processing Emotional Expression In The Dance Of A Foreign Culture: Gestural Responses Of Germans And Koreans To Ballet And Korean Dance, Zi Hyun Kim, Hedda Lausberg

Journal of Movement Arts Literacy Archive (2013-2019)

Artistic dance differs between cultures with regard to the formal movement repertoire and methods to represent dancer's emotions. The present study explores how differently the spectators perceive the dance scenes of their own and foreign cultures. We showed German and Korean participants sad and happy dance scenes of the French ballet Giselle and Korean dance Sung-Mu. To learn the perceived thoughts and feelings of the participant from the dance scenes, we analyzed the frequency of their hand movements and gestures, which were accompanied by verbal descriptions of the participant's appreciation immediately after observation of the dance stimuli. The videotaped …

Carbonic Anhydrase Inhibition Selectively Prevents Amyloid B Neurovascular Mitochondrial Toxicity, María E. Solesio, Pablo M. Peixoto, Ludovic Debure, Stephen M. Madamba, Mony J. De Leon, Thomas Wisniewski, Evgeny V. Pavlov, Silvia Fossati

Publications and Research

Mounting evidence suggests that mitochondrial dysfunction plays a causal role in the etiology and progression of Alzheimer’s disease (AD). We recently showed that the carbonic anhydrase inhibitor (CAI) methazolamide (MTZ) prevents amyloid b (Ab)-mediated onset of apoptosis in the mouse brain. In this study, we used MTZ and, for the first time, the analog CAI acetazolamide (ATZ) in neuronal and cerebral vascular cells challenged with Ab, to clarify their protective effects and mitochondrial molecular mechanism of action. The CAIs selectively inhibited mitochondrial dysfunction pathways induced by Ab, without affecting metabolic function. ATZ was effective at concentrations 10 times lower than …

When Less Is More: Mindfulness Predicts Adaptive Affective Responding To Rejection Via Reduced Prefrontal Recruitment, Alexandra M. Martelli, David S. Chester, Kirk Warren Brown, Naomi I. Eisenberger, C. Nathan Dewall

Psychology Faculty Publications

Social rejection is a distressing and painful event that many people must cope with on a frequent basis. Mindfulness—defined here as a mental state of receptive attentiveness to internal and external stimuli as they arise, moment-to-moment—may buffer such social distress. However, little research indicates whether mindful individuals adaptively regulate the distress of rejection—or the neural mechanisms underlying this potential capacity. To fill these gaps in the literature, participants reported their trait mindfulness and then completed a social rejection paradigm (Cyberball) while undergoing functional magnetic resonance imaging. Approximately 1 hour after the rejection incident, participants reported their level of distress during …

Transcriptional Correlates Of Proximal-Distal Identify And Regeneration Timing In Axolotl Limbs, S. Randal Voss, David Murrugarra, Tyler B. Jensen, James R Monaghan

Neuroscience Faculty Publications

Cells within salamander limbs retain memories that inform the correct replacement of amputated tissues at different positions along the length of the arm, with proximal and distal amputations completing regeneration at similar times. We investigated the possibility that positional memory is associated with variation in transcript abundances along the proximal-distal limb axis. Transcripts were deeply sampled from Ambystoma mexicanum limbs at the time they were administered fore arm vs upper arm amputations, and at 19 post-amputation time points. After amputation and prior to regenerative outgrowth, genes typically expressed by differentiated muscle cells declined more rapidly in upper arms while cell …

Defining The Radioresponse Of Mossy Cells, Devon Ivy

Electronic Theses, Projects, and Dissertations

Clinical radiotherapy is used to treat a variety of brain tumors within the central nervous system. While effective, it can result in progressive and debilitating cognitive impairment that can diminish quality of life. These impairments have been linked to hippocampal dysfunction and corresponding deficits in spatial learning and memory. Mossy cells are a major population of excitatory neurons located within the dentate hilus and highly involved in hippocampal circuitry. They play critical roles in spatial navigation, neurogenesis, memory, and are particularly vulnerable to a variety of neurotoxic insults. However, their sensitivity to ionizing radiation has yet to be investigated in …

Socioeconomic Disparities In Academic Achievement: A Multi-Modal Investigation Of Neural Mechanisms In Children And Adolescents, Maya L. Rosen, Margaret A. Sheridan, Kelly A. Sambrook, Andrew N. Meltzoff, Katie A. Mclaughlin

Neuroscience: Faculty Publications

Growing evidence suggests that childhood socioeconomic status (SES) influences neural development, which may contribute to the well-documented SES-related disparities in academic achievement. However, the particular aspects of SES that impact neural structure and function are not well understood. Here, we investigate associations of childhood SES and a potential mechanism—degree of cognitive stimulation in the home environment—with cortical structure, white matter microstructure, and neural function during a working memory (WM) task across development. Analyses included 53 youths (age 6–19 years). Higher SES as reflected in the income-to-needs ratio was associated with higher parent-reported achievement, WM performance, and cognitive stimulation in the …

Myelin As An Inflammatory Mediator: Myelin Interactions With Complement, Macrophages, And Microglia In Spinal Cord Injury, Timothy J. Kopper, John C. Gensel

Spinal Cord and Brain Injury Research Center Faculty Publications

Spinal cord injury (SCI) triggers chronic intraspinal inflammation consisting of activated resident and infiltrating immune cells (especially microglia/macrophages). The environmental factors contributing to this protracted inflammation are not well understood; however, myelin lipid debris is a hallmark of SCI. Myelin is also a potent macrophage stimulus and target of complement‐mediated clearance and inflammation. The downstream effects of these neuroimmune interactions have the potential to contribute to ongoing pathology or facilitate repair. This depends in large part on whether myelin drives pathological or reparative macrophage activation states, commonly referred to as M1 (proinflammatory) or M2 (alternatively) macrophages, respectively. Here we review …

Reflections On Contributing To “Big Discoveries” About The Fly Clock: Our Fortunate Paths As Post-Docs With 2017 Nobel Laureates Jeff Hall, Michael Rosbash, And Mike Young, Kathleen King Siwicki, P. E. Hardin, J. L. Price

Biology Faculty Works

In the early 1980s Jeff Hall and Michael Rosbash at Brandeis University and Mike Young at Rockefeller University set out to isolate the period (per) gene, which was recovered in a revolutionary genetic screen by Ron Konopka and Seymour Benzer for mutants that altered circadian behavioral rhythms. Over the next 15 years the Hall, Rosbash and Young labs made a series of groundbreaking discoveries that defined the molecular timekeeping mechanism and formed the basis for them being awarded the 2017 Nobel Prize in Physiology or Medicine. Here the authors recount their experiences as post-docs in the Hall, Rosbash and Young …

“Musical Exercise” For People With Visual Impairments: A Preliminary Study With The Blindfolded, Ridwan Ahmed Khan, Myounghoon Jeon, Tejin Yoon

Michigan Tech Publications, Part 1

Performing independent physical exercise is critical to maintain one's good health, but it is specifically hard for people with visual impairments. To address this problem, we have developed a Musical Exercise platform for people with visual impairments so that they can perform exercise in a good form consistently. We designed six different conditions, including blindfolded or visual without audio conditions, and blindfolded or visual with two different types of audio feedback (continuous vs. discrete) conditions. Eighteen sighted participants participated in the experiment, by doing two exercises - squat and wall sit with all six conditions. The results show that Musical …

Self-Regulation, Threat Perception, And Inhibitory Control: An Fmri Investigation Of Children With Adhd, Erin Kaseda

Undergraduate Honors Theses

This thesis examines the role of perceived parental support on adolescents aged 12-19 who have been diagnosed with attention-deficit/hyperactivity disorder (ADHD). Specifically, the study focused on inhibitory control, one form of cognitive executive control often implicated in ADHD, in three ways: first, through the use of a Go/No-Go task during a functional MRI scan of the brain; second, through the use of a neuropsychological cognitive battery using the NIH Toolbox; and third, through a qualitative interview that examined self-control in school and home contexts. Contrary to the initial hypothesis, parental support was found to be negatively correlated with inhibitory control …

Effect Sizes In Task-Based Functional Magnetic Resonance Imaging, Tyler Kellett

Celebration of Learning

Task-based functional magnetic resonance imaging (t-fMRI) techniques have changed the way scientists probe the neurological mechanisms underlying behavior. However, there are many problems surrounding t-fMRI especially underpowered studies leading to misleading effect sizes. This study is using a recent large data collection study, the Human Connectome Project, to investigate effect sizes in specific regions of the brain involving working memory. Previous studies have come up with relatively small effect sizes due to small sample sizes and large regions of interest (ROI). This study is concentrated on using more precise ROI called parcels to find larger effect sizes.

An Investigation Of The Cortical Learning Algorithm, Anthony C. Samaritano

Theses and Dissertations

Pattern recognition and machine learning fields have revolutionized countless industries and applications from biometric security to modern industrial assembly lines. The fields continue to accelerate as faster, more efficient processing hardware becomes commercially available. Despite the accelerated growth of the pattern recognition and machine learning fields, computers still are unable to learn, reason, and perform rudimentary tasks that humans and animals find routine. Animals are able to move fluidly, understand their environment, and maximize their chances of survival through adaptation - animals demonstrate intelligence. A primary argument in this thesis that we have not yet achieved a level of intelligence …

The Role Of Interleukin-1 Beta In Methamphetamine Mediated Increases In Dopamine Release Within The Mesolimbic Pathway, Anneke Klomp, Ben Lee, Dr. Scott Steffensen

Journal of Undergraduate Research

In this study we wanted to determine the effect that Interleukin-1 Beta (IL-1𝛃) would have in changing the effects that methamphetamines have on dopamine release in the nucleus accumbens (reward center of the brain). It has been well established previously that methamphetamines increases dopamine levels in the nucleus accumbens. Given that IL-1𝛃 increases inflammation in the brain which has been seen to be involved in dopamine release and that IL-1𝛃 is able to act on other parts of the brain, we suspected that by inhibiting IL-1𝛃 we would see a decrease in dopamine response to methamphetamines. If the IL-1𝛃 blocker, …

The Involvement Of The Ip3 Receptor In The Rewarding/Addictive Properties Of Methamphetamine, Mark Woodbury, Dr. Scott Steffensen

Journal of Undergraduate Research

Methamphetamine (METH) is a very powerful psychoactive drug that is highly addictive and toxic to the brain. Its use and abuse has been rising in recent years, and certain reports indicate that amphetamine-like drugs are the second most abused drugs worldwide. The side effects of METH abuse are varied and serious in nature, including: hyperthermia, tooth decay, heart attack, seizures, stroke, skin lesions, memory loss, confusion, anxiety, depression, psychosis, Parkinson’s Disease, and increased severity of HIV/AIDS (Chang et al., 2005; Curtin et al., 2015; Thanos et al., 2017). Despite these devastating effects, many of those addicted do not or cannot …

Neural And Behavioral Correlates Of Attentional Inhibition Training And Perceptual Discrimination Training In A Visual Flanker Task, Robert D. Melara, Shalini Singh, Denise A. Hien

Publications and Research

Two groups of healthy young adults were exposed to 3 weeks of cognitive training in a modified version of the visual flanker task, one group trained to discriminate the target (discrimination training) and the other group to ignore the flankers (inhibition training). Inhibition training, but not discrimination training, led to significant reductions in both Garner interference, indicating improved selective attention, and in Stroop interference, indicating more efficient resolution of stimulus conflict. The behavioral gains from training were greatest in participants who showed the poorest selective attention at pretest. Electrophysiological recordings revealed that inhibition training increased the magnitude of Rejection Positivity …

At-Home Transcranial Direct Current Stimulation (Tdcs) With Telehealth Support For Symptom Control In Chronically-Ill Patients With Multiple Symptoms, Alexa Riggs, Vaishali Patel, Bhaskar Paneri, Russell K. Portenoy, Marom Bikson, Helena Knotkova

Publications and Research

Transcranial direct current stimulation (tDCS) delivered in multiple sessions can reduce symptom burden, but access of chronically ill patients to tDCS studies is constrained by the burden of office-based tDCS administration. Expanded access to this therapy can be accomplished through the development of interventions that allow at-home tDCS applications.

Objective: We describe the development and initial feasibility assessment of a novel intervention for the chronically ill that combines at-home tDCS with telehealth support. Methods: In the developmental phase, the tDCS procedure was adjusted for easy application by patients or their informal caregivers at home, and a tDCS protocol with specific …
