Individual Differences In Age And Testosterone Are Uniquely Associated With Neural Oscillatory Activity Serving Verbal Working Memory In Children And Adolescents, 2024 University of Nebraska Medical Center
Individual Differences In Age And Testosterone Are Uniquely Associated With Neural Oscillatory Activity Serving Verbal Working Memory In Children And Adolescents, Abraham D. Killanin
Theses & Dissertations
During the sensitive period of adolescence, the human brain undergoes dynamic changes in structure and function resulting in vast executive function gains. Verbal working memory (VWM) is one executive function that serves as a foundation to language acquisition, reading, and learning. Many have examined the development of VWM in youth, but few have probed age-related changes in the underlying neural oscillatory dynamics, and none have examined testosterone-related changes. We recorded magnetoencephalography during a modified Sternberg VWM task in 82 youth participants aged 6 – 14 years old and collected salivary testosterone samples. Significant oscillatory responses were identified and imaged using …
Exploring Available Information On The Gut-Brain Axis And Alzheimer’S Disease For Clinicians Making Dietary Recommendations: A Scoping Review, 2024 East Tennessee State University
Exploring Available Information On The Gut-Brain Axis And Alzheimer’S Disease For Clinicians Making Dietary Recommendations: A Scoping Review, Megan Gibson
Electronic Theses and Dissertations
Abstract: Alzheimer’s Disease (AD) is a complex neurodegenerative disease that requires interprofessional collaboration. Pharmacological options are currently ineffective, increasing the need for preventative strategies to combat the rise of AD. Considerations of gut-targeted interventions have increased as a key component in the prevention of AD, based on the understanding that the state of the gut microbiome can impact cognitive function through the pathway known as the gut-brain axis.
Methods: This scoping review explored information on the gut-brain axis in persons with AD. A comprehensive search was conducted in November 2023. Forty reviews and 13 human studies were analyzed.
Results: There …
Biophysical Model Of Retraction Motor Neurons And Their Modification By Operant Conditioning, 2024 The Texas Medical Center Library
Biophysical Model Of Retraction Motor Neurons And Their Modification By Operant Conditioning, Maria Rasheed
Dissertations & Theses (Open Access)
Operant conditioning (OC) is a form of associative learning in which an animal modifies its behavior based on the consequences that follow that behavior. Despite its ubiquity, the underlying mechanisms of OC are poorly understood. Insights into the mechanisms of OC can be obtained by studying Aplysia feeding behavior as it can be modified by OC. This behavior is mediated by a central pattern generator (CPG) network in the buccal ganglia that contains a relatively small number of neurons. This CPG generates rhythmic motor patterns (BMPs) that move food into the gut by closing a tongue-like structure (i.e., radula) during …
P300 Event-Related Potential Responses To Self-Relevant Stimuli, 2024 East Tennessee State University
P300 Event-Related Potential Responses To Self-Relevant Stimuli, Jordan Razzak
Electronic Theses and Dissertations
Previous literature has suggested an apparent P300 sensitivity to self-relevant stimuli. To further explore this relationship, we asked participants to submit 10 photos, each of a particular category (e.g. footwear, plants), to be used as either targets or distractors in a given condition of an oddball task. Furthermore, we attempted to see whether the effect of self-relevance on the P300 could be induced in a participant by allowing them to study a set of unique photos which would then be used as targets. Our analysis suggested that P300 amplitude elicited in response to self-relevant stimuli used as targets was statistically …

The Anatomical Embodiment Of Morning Routines In The Reduction Of Anxiety: An Intervention, 2024 Lesley University
The Anatomical Embodiment Of Morning Routines In The Reduction Of Anxiety: An Intervention, Natalie Wright
Expressive Therapies Capstone Theses
The topic under investigation is whether physically embodying a morning routine that was designed through the lens of Laban Bartenieff Movement Analysis (LBMA) will reduce daily symptoms of individuals diagnosed with Generalized Anxiety Disorder.
Since morning routines play a significant part in one’s preparation for the day, I created an individualized LBMA morning routine for a specific client to embody. In addition to the routine, the client documented the process of their anxiety levels on a weekly basis. This client was a white, female, 19-year-old, lesbian college student who was previously diagnosed with Generalized Anxiety Disorder (GAD). The movement analysis …
Exposure To The Trier Social Stress Test Enhances Central Detail Memory, Reduces False Memory, And Results In Intrusive Memories That Last For Days, 2024 Ohio Northern University
Exposure To The Trier Social Stress Test Enhances Central Detail Memory, Reduces False Memory, And Results In Intrusive Memories That Last For Days, Mercedes L. Stanek, Kayla Boaz, Taylor D. Niese, Kristen E. Long, Matthew S. Risner, John G. Blasco, Koen N. Suzelis, Kelsey M. Siereveld, Boyd R. Rorabaugh, Phillip R. Zoladz
ONU Student Research Colloquium
Recent work has used a modified version of the well-known laboratory stressor, the Trier Social Stress Test (TSST), to study participant memory for a stressful experience. The paradigm is useful because, unlike most studies examining stress effects on memory, it allows investigators to measure what participants remember about the stressor, not unrelated information. It also presents an opportunity to model other stress-related symptoms, such as intrusive memories, but these have yet to be assessed with this paradigm. Intrusive memories have been notoriously difficult to measure in laboratory settings; most of this research involves participants watching arousing videos and subsequently reporting …
Technology To Support Aging In Place: The Perspective Of Caregivers, 2024 Sheridan College
Technology To Support Aging In Place: The Perspective Of Caregivers, Sophie Meng
Capstone Research Posters
As the world population ages, more older adults prefer to age in a place which offers them better life qualities and autonomy but demands increased commitments of caregivers. The development of technology can be great aid in daily lives yet significant gaps persist in supporting older adults with impaired cognition aging in place. This study aimed to explore the perspective of caregivers on technology when assisting cognition impaired older adults at home. It sought to understand the needs of the caregivers in this context. The study also briefly addressed Artificial Intelligence (AI) in caregiving, considering its growing use. Five caregivers …
Associations Between Early Childhood Sleep, Memory Function, And Brain Development Across The Nap Transition, 2024 University of Massachusetts Amherst
Associations Between Early Childhood Sleep, Memory Function, And Brain Development Across The Nap Transition, Sanna Lokhandwala
Doctoral Dissertations
Preschool-age children often distribute their sleep across a midday nap and overnight sleep. Skipping the nap is suggested to increase the duration and depth of deep sleep (i.e., slow wave activity; SWA). Moreover, missing the midday nap has been shown to impair learning processes. This may be because children’s brains at this point in development are immature, necessitating the intervening nap period to strengthen memories before they are forgotten. Nonetheless, at some point during the preschool years, many children begin transitioning naturally out of napping. It is unclear whether the memory benefits of overnight SWA after a skipped nap depend …
Frontoparietal Circuitry Underlying Saccade Control In The Common Marmoset, 2024 Western University
Frontoparietal Circuitry Underlying Saccade Control In The Common Marmoset, Janahan Selvanayagam
Electronic Thesis and Dissertation Repository
Our visual world is full of far more stimuli than can be processed simultaneously. Yet we are able to efficiently extract behaviourally relevant information from a scene, primarily by performing rapid saccadic eye movements. These processes are under the control the frontoparietal network, two critical nodes of which are: the lateral intraparietal area (LIP) and the frontal eye fields (FEF). Extensive research in the macaque has causally implicated these areas in visual attention and oculomotor control. However, the organization of the activity of single neurons in these areas across cortical layers remains poorly understood as these regions are deep within …
Harmonious Healing: A Review Of Music Therapy, A Humanities-Based Approach To Alzheimer’S Disease Treatment, 2024 University of Kentucky
Harmonious Healing: A Review Of Music Therapy, A Humanities-Based Approach To Alzheimer’S Disease Treatment, Rohan K. Desai
Kentucky Undergraduate Journal for the Health Humanities
Alzheimer’s Disease (AD) is a progressive neurodegenerative disease often characterized by memory loss, confusion, and overall cognitive decline. The aging global population has, in recent years, highlighted the fundamental lack of pharmacological treatments for individuals facing an AD diagnosis. In response, a growing body of research has shifted focus to non-pharmacological humanities-based interventions. One such intervention has been music therapy (MT). Music-focused measures have shown great promise as a method of slowing cognitive decline, but mixed results in the literature warrant the need for further investigation. Often, socioeconomic barriers can limit an individual’s access to drug-related treatments, but the affordable …

Birds, Bats And Minds. Tales Of A Revolutionary Scientist: Donald R. Griffin. Volume Three, Carolyn A. Ristau
eBooks
In this three-volume biography, we revisit the life and accomplishments of the revolutionary scientist, Donald R. Griffin. He encountered a lifetime of initial hostile resistance to his ideas and studies; now they are largely accepted. He and a colleague discovered the phenomenon of echolocation used by bats to navigate and capture insects, proposed that birds navigate guided by such cues as the sun and stars, and suggested that animals are likely aware, thinking and feeling beings. Forty interviews with his colleagues and friends help us understand the young emerging scientist and the mature researcher. We learn about his and others’ …
The Divided Self: Internal Conflict In Literature, Philosophy, Psychology, And Neuroscience, 2024 The Graduate Center, City University of New York
The Divided Self: Internal Conflict In Literature, Philosophy, Psychology, And Neuroscience, Yulia Greyman
Dissertations, Theses, and Capstone Projects
This thematic project examines the notion of self-division, particularly in terms of the conflict between cognition and metacognition, across the fields of philosophy, psychology, and, most recently, the cognitive and neurosciences. The project offers a historic overview of models of self-division, as well as analyses of the various problems presented in theoretical models to date. This work explores how self-division has been depicted in the literary works of Edgar Allan Poe, Don DeLillo, and Mary Shelley. It examines the ways in which artistic renderings alternately assimilate, resist, and/or critique dominant philosophical, psychological, and scientific discourses about the self and its …
Neurochemical Signaling Of Reward-Based Learning In Ventral Tegmental Area Dopamine Neurons, 2024 The Graduate Center, City University of New York
Neurochemical Signaling Of Reward-Based Learning In Ventral Tegmental Area Dopamine Neurons, Kyla F. Wholley
Dissertations, Theses, and Capstone Projects
Ventral tegmental area (VTA) dopamine neurons signal and participate in reward-related learning. Specifically, dopamine is postulated to encode reward-related environmental stimuli to compute reward prediction errors (RPEs). It is through the computation and maintenance of RPEs that learning occurs. However, little is known about the neural mechanisms that underlie how dopamine neurons compute RPEs and facilitate reward-related learning. The present study utilized fiber photometry in conjunction with a Pavlovian reward-based task to identify how GABA inputs to VTA dopamine neurons contribute to the computation of RPEs and reward-based behavior. Activity of GABA inputs to VTA dopamine neurons increased for reward-predicting …

BACKGROUND: Smartphone-based cognitive assessments have emerged as promising tools, bridging gaps in accessibility and reducing bias in Alzheimer disease and related dementia research. However, their congruence with traditional neuropsychological tests and usefulness in diverse cohorts remain underexplored.
METHODS AND RESULTS: A total of 406 FHS (Framingham Heart Study) and 59 BHS (Bogalusa Heart Study) participants with traditional neuropsychological tests and digital assessments using the Defense Automated Neurocognitive Assessment (DANA) smartphone protocol were included. Regression models investigated associations between DANA task digital measures and a neuropsychological global cognitive
CONCLUSIONS: Our findings demonstrate that smartphone-based cognitive assessments exhibit concurrent validity with a …
Target Selection And Enhancement During Attentional Tracking, 2024 Dartmouth College
Target Selection And Enhancement During Attentional Tracking, Marvin R. Maechler
Dartmouth College Ph.D Dissertations
At any waking moment, we are bombarded with more sensory information than we can fully process. Attention is necessary to deal with the dynamic world we live in. One fundamental function of vision and attention is to keep track of moving objects, but what are the targets of attention during tracking?
One of the first theories of attentional tracking predicted that targets would be selected at early processing stages. By employing the double-drift illusion, which dissociates physical and perceived positions of moving objects, we investigated which of these positions is selected for tracking. Contrary to earlier theories and in line …
