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 …

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 …

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 …

Evaluating The Potential Of Using Eeg To Monitor Cognitive Workload In Simulated Suborbital Flight, Erik Seedhouse Phd
Journal of Aviation/Aerospace Education & Research
Mental workload can be assessed using electrophysiological measures of brain activity, such as electroencephalography (EEG). EEG signals reveal cortical electrical activity. This cortical activity was recorded using specialized headsets. The focus of this research was to study cognitive performance (CP) in four pilots during simulated suborbital flights under nominal day and night profiles and under contingency day and night profiles. A 14-channel EMOTIV EEG headset measured the participants' brain activity while they flew simulated flights in a Suborbital Spaceflight Simulator (SSFS). Several sessions of EEG data were recorded from each subject, and feature extraction was applied. Data revealed that real-time …

Visual Imagery Subcategories And Their Neural Associations, 2023 University of Central Florida
Visual Imagery Subcategories And Their Neural Associations, Miguel Ibarguren
Undergraduate Scholarship and Creative Works
This literature review compiles research findings related to the brain areas associated with various visual imagery subcategories and explores their contributions to them. Through a search procedure, four research projects were used to identify ten distinct brain areas that demonstrated greater involvement in visual imagery. The visual imagery subcategories discussed in these research projects, and investigated in this review, include scene construction, episodic memory, imagery vividness, and visuospatial imagery. Scene construction was found to utilize the parahippocampal gyrus, hippocampus, retrosplenial cortex, and posterior parietal cortex. Episodic memory involves the same areas as scene construction, but also includes the precuneus and …
Cerebrospinal Fluid Biomarkers Not Associated With Neurologic Compromise Among Mild Cognitively Impaired Reverters With Parkinson's Disease, 2023 California State University, San Bernardino
Cerebrospinal Fluid Biomarkers Not Associated With Neurologic Compromise Among Mild Cognitively Impaired Reverters With Parkinson's Disease, Cameron Ryczek
Electronic Theses, Projects, and Dissertations
Parkinson's Disease (PD) is a neurodegenerative disease characterized by motor (e.g. tremors) and non-motor symptoms (e.g. cognitive impairment). PD patients' change in cognitive functioning can be observed using the following classifications: cognitively intact, mild cognitive impairment (MCI), or dementia (PDD). MCI has many subtypes, one of which is MCI reversion which is defined as those with MCI at one time point reverting to cognitively intact later. While there is limited research into the utility of MCI reversion and its relationship with cerebrospinal fluid (CSF) biomarkers in PD, this study will begin to elucidate this relationship. To this end, data from …
Head Stabilization And Cortical Activation In Contact Sport Athletes During Walking Under Different Visual Task Constraints, 2023 University of Massachusetts Amherst
Head Stabilization And Cortical Activation In Contact Sport Athletes During Walking Under Different Visual Task Constraints, Sam Zeff
Doctoral Dissertations
Contact sport participation exposes athletes to repetitive sub-concussive head impacts, which have been shown to elicit cortical neurophysiologic, cognitive, and motor performance alterations that have the potential to disrupt visual perception. Despite the growing concern regarding sub-concussive impacts, our understanding of their implications on motor performance and risk for further injury is limited. A stable head provides a consistent perceptual platform for the visual and vestibular sensory systems, but the effects of contact sport participation on head stability and visual perception remain poorly understood. The goal of this dissertation was to understand whether contact sport participation modifies athletes’ ability to …
Affective Liking Influences Reward Processing In Depression: A Computational Eeg Approach, 2023 University of New Mexico
Affective Liking Influences Reward Processing In Depression: A Computational Eeg Approach, Garima Singh
Psychology ETDs
Reinforcement learning (RL) enables agents to learn through interaction with their environment. This empowers individuals to optimize actions in complex and dynamic settings. The component of event related potential (ERP) termed as the Reward Positivity (RewP) evidently signifies a fundamental reward prediction error (RPE) associated with rewards. This characteristic implies that it represents a fundamental computational process in the assessment of RL. When a reward is particularly pleasurable or liked by an individual, it tends to elicit an amplified RewP signal, reflecting the heightened positive affect. RPE arises from disparities between anticipated and actual rewarding outcomes and is known to …
Neural Responses To Magnetic Orientation Information In Songbirds, 2023 The University of Western Ontario
Neural Responses To Magnetic Orientation Information In Songbirds, Madeleine Ir Brodbeck
Electronic Thesis and Dissertation Repository
Effective navigation and orientation is essential for animals to survive. The study of migratory birds provides insights into these processes, particularly through mechanisms like the geomagnetic compass, which uses Earth's magnetic field for directional information. A brain region in songbirds relevant to this is cluster N, known for its potential role in processing geomagnetic information. Notably, cluster N appears exclusive to nocturnally migratory birds, being active solely at night, and lesion studies reveal that an intact cluster N is necessary for geomagnetic compass orientation. However, given the scarcity of empirical data concerning cluster N, substantial questions persist regarding its function. …

Research Colloquium
Understanding the effects of stress on behavior and cognition is important due to its impact on mental health and wellbeing (Schneiderman et al. 2005). Translational animal research can contribute to the development of new treatments that can improve therapeutic outcomes and our understanding of the neurobiology of stress. In the present study, we complement behavioral stress reactivity with immunohistochemical localization of oxytocin in the hypothalamus, a neuropeptide that regulates stress (Neumann & Slattery, 2016). Oxytocin has potential therapeutic use for mental health disorders (Neumann & Slattery, 2016), and the effects of oxytocin seem to be sexually dimorphic (Love, 2018). Using …

The Neural Sequalae Of Subjectively Experiencing Autobiographical Memories From The Remote Past And Recent Present Using Fmri, Ava G. Peruski, Nim Singh, Brendan E. Depue
The Cardinal Edge
Autobiographical memory is central to one's sense of self and continuity from past to present. Despite this, there is little research on the neural correlates underlying individual subjective experience of autobiographical memory and how that is related to brain phenomena (i.e., activity, communication). The purpose of this study was to help minimize this gap. We recruited twenty healthy adult participants, who were asked to generate memory cues (1-3 word descriptions) for locations and objects from their early and recent life. After 24 hours, participants were shown these cues then asked to recall the appropriate memory while in an fMRI scanner. …
Selective Recruitment Of Cerebellum In Cognition, 2023 Western University
Selective Recruitment Of Cerebellum In Cognition, Ladan Shahshahani
Electronic Thesis and Dissertation Repository
Previous studies of cerebellar function in humans have shown that it is activated by a myriad of tasks ranging from motor learning and language to working memory and more. These studies have prompted a deviation from the traditional view of the cerebellum as a purely motor structure. However, the precise contribution of the cerebellum to these tasks remains ambiguous.
A prevalent assumption in fMRI studies is interpreting BOLD activation as evidence of the cerebellum's involvement in specific tasks. However, this interpretation is potentially misleading, especially considering that the BOLD signal predominantly represents cerebellar input, with output activity largely absent. Consequently, …
