Neural Correlates Of Recognition Memory And Metamemory In Breast Cancer Survivors: An Event-Related Potential Study, Dishari Zaman Azad Jun 2026

Neural Correlates Of Recognition Memory And Metamemory In Breast Cancer Survivors: An Event-Related Potential Study, Dishari Zaman Azad

Dissertations, Theses, and Capstone Projects

Breast cancer survivors (BCS) often report noticeable cognitive difficulties despite showing limited impairment on standardized neuropsychological tests. Some have theorized that this is simply an insensitivity of standardized testing to subtle cognitive changes (test-insensitivity hypothesis), whereas others have suggested there are early neural changes that are detected by patients but precede detection by these tests (early signal hypothesis) or that when they achieve normal performance, it is through saliently effortful compensatory processes (compensation hypothesis). The present study tested these theories by assessing metamemory and recognition memory retrieval in BCS and non-cancer controls (NCC) using both behavioral and event-related potential (ERP) …


Neurophysiological Signatures Of Perceived Control In The Human Brain: An Electroencephalography Study, Megan Staehling May 2026

Neurophysiological Signatures Of Perceived Control In The Human Brain: An Electroencephalography Study, Megan Staehling

Honors Theses

Perceived control is defined as the belief that one’s actions can influence the outcomes in the environment. It plays an important role in decision-making, motivation, and emotional regulation. Previous studies suggest that perceived control shapes how the brain processes both reward and punishment stimuli. However, the neural mechanisms underlying this process are still unclear. The present study examined the neurophysiological correlates of perceived control during a decision-making task. Electroencephalography (EEG) was used to record the neural activity of twenty-nine undergraduate students while they completed the Choice Task. Participants associated visual cues with different levels of control over trials involving monetary …


Neural Mechanisms Underlying Jung’S Active Imagination: A Review And Hypothesis, Charles R. Fox May 2026

Neural Mechanisms Underlying Jung’S Active Imagination: A Review And Hypothesis, Charles R. Fox

Journal of Conscious Evolution

Active imagination is a key technique of Jungian analysis. Despite its centrality, and its potential importance beyond Jungian psychology to the area of systems neuroscience, psychology, and consciousness studies, there are no known neurological mechanisms underlying this psychological phenomenon. There is a history of using the types of mental imagery used in active imagination to explore consciousness. The development and use of active imagination is briefly reviewed, and a case is developed that the neurology underlying active imagination would be fruitfully explored by considering it a special case of mystical experience. Active imagination primarily uses the right hemisphere processing of …

Renewal Of The Mind: Forgiveness Through The Lens Of Christian Faith And Neuroscience, Khelen Walsh Nov 2025

Renewal Of The Mind: Forgiveness Through The Lens Of Christian Faith And Neuroscience, Khelen Walsh

University Honors Theses

Within Christian theology, forgiveness is a foundational concept that is often understood as a divine command, a spiritual practice, and a path toward reconciliation and personal growth. Recent neuroscientific research further supports this viewpoint, providing data that shows forgiveness engages neural systems responsible for emotional regulation, empathy, moral reasoning, and perspective-taking. Through neuroplasticity, repeated acts of forgiveness reshape the brain, strengthen connections between prefrontal and limbic regions, reduce amygdala reactivity, and enhance emotional stability and cognitive flexibility. Although forgiveness offers many benefits, modern culture frequently distorts its meaning, framing it as a sign of weakness, gullibility, or a form of …


Behavioral And Neural Evidence For Perceptual Inference Of Position, Sharif Saleki Oct 2024

Behavioral And Neural Evidence For Perceptual Inference Of Position, Sharif Saleki

Dartmouth College Ph.D Dissertations

Extensive neuroscientific research has advanced our knowledge of the mechanisms involved in the detection and recognition of visual stimuli. However, to guide flexible behavior in a changing world, the brain must also construct stable and coherent perceptual representations from retinal images that are often ambiguous. To resolve ambiguities and uncertainties, the visual system combines its input with other sources of information such as context and prior knowledge to infer the most likely interpretation of a scene. Thus, perception is inherently an inferential process that goes beyond simple detection or recognition of stimuli. Although inference has been studied in many areas …


The Neuroscience Of Mindfulness Based Art Therapy: A Literature Review, Elizabeth Strasser Aug 2024

The Neuroscience Of Mindfulness Based Art Therapy: A Literature Review, Elizabeth Strasser

Expressive Therapies Capstone Theses

Art therapy and neuroscience are two fields which are currently growing and expanding with the development of new technology which allows for therapists and scientists to advance their understanding of how the brain and the body respond to the world around us. The interaction between the brain, body, and environment is complex, and for the sake of clarity for this thesis this interaction will be conceptualized through the lens of the body-mind model, polyvagal theory, neuroaesthetics, the flow state, mindfulness, sensory engagement, and art as therapy. Neuroscience in relation to psychology can be used to develop a deeper understanding of …


External And Internal Attribution In Human-Agent Interaction: Insights From Neuroscience And Virtual Reality, Nina Lauharatanahirun, Andrea Won, Angel Hsing-Chi Hwang Jun 2024

External And Internal Attribution In Human-Agent Interaction: Insights From Neuroscience And Virtual Reality, Nina Lauharatanahirun, Andrea Won, Angel Hsing-Chi Hwang

Human-Machine Communication

Agents are designed in the image of humans, both internally and externally. The internal systems of agents imitate the human brain, both at the levels of hardware (i.e., neuromorphic computing) and software (i.e., neural networks). Furthermore, the external appearance and behaviors of agents are designed by people and based on human data. Sometimes, these humanlike qualities of agents are purposely selected to increase their social influence over human users, and sometimes the human factors that influence perceptions of agents are hidden. Inspired by Blascovich’s “threshold of social influence’, a model designed to explain the effects of different methods of anthropomorphizing …


Competition And Criticality In Cortical Neural Circuits Underlie Behavior And Optimize Working Memory, Jacob Harrison Barfield May 2024

Competition And Criticality In Cortical Neural Circuits Underlie Behavior And Optimize Working Memory, Jacob Harrison Barfield

Graduate Theses and Dissertations

One of the primary goals of neuroscience is to explain how brain function emerges from dynamic interactions among large populations of neurons. A long-standing hypothesis at the interface of physics and neuroscience posits that neural circuits may operate close to the critical point of a phase transition. In this dissertation, we will investigate a new form of criticality and the implications that it has in working memory and the generation of voluntary body movements. We will utilize this new form of criticality to investigate the functional benefits that can be harnessed by operating near the critical point when performing working …


Biophysical Model Of Retraction Motor Neurons And Their Modification By Operant Conditioning, Maria Rasheed May 2024

Biophysical Model Of Retraction Motor Neurons And Their Modification By Operant Conditioning, Maria Rasheed

Dissertations and 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 …


The Role Of Spreading Depolarizations In Mild Traumatic Brain Injuries, Natalie J. Pinkowski Apr 2024

The Role Of Spreading Depolarizations In Mild Traumatic Brain Injuries, Natalie J. Pinkowski

Biomedical Sciences ETDs

Mild traumatic brain injuries (mTBIs) often lead to acute symptoms like disorientation and discoordination, but the underlying mechanisms are unknown. Although most patients recover quickly from a single mTBI, repeated injuries can be debilitating. After an mTBI, a neurometabolic cascade produces metabolic burden and vulnerability. Spreading depolarizations (SDs) have been observed after mTBIs. Here we investigated SDs’ role in short-term motor behavioral deficits post-mTBI. We hypothesized that SDs contribute to the deficits, and exacerbated symptoms after repeated mTBIs. To test this, we used acute motor behavioral tests and long-term behavioral and cognitive tests after initiating SDs by mTBI, chemical, or …


Neurocinematics And Empathy: How Cognitive Neuroscience Enhances Our Understanding Of Emotional Responses Of Film, Kira Trinity Jan 2024

Neurocinematics And Empathy: How Cognitive Neuroscience Enhances Our Understanding Of Emotional Responses Of Film, Kira Trinity

Cal Poly Humboldt theses and projects

Cinema is a medium that is beloved around the globe since its inception over a century ago. There have been speculations on how it is that cinema works, from editing to emotional processing of the story, but only recently have we begun to explore the inner workings of cinematic impact on the brain. In this paper we will review research on cinematic impact and define cinematic editing, discuss the birth of “neurocinematics”, highlight what we have observed with regards to neuroimaging and empathy when viewing films, and speculate on how our responses to cinema may be driven by the Mirror …


Brainwaves, Memory, And Reward, Rebecca Mccune Sep 2023

Brainwaves, Memory, And Reward, Rebecca Mccune

Dissertations, Theses, and Capstone Projects

The development of effective educational curricula for enhancing learning involves the crucial consideration of effort and rewards. In the realm of education, teachers commonly employ rewards as motivational tools. Traditionally, these rewards are given to students as a recognition of their successful performance. However, a thought-provoking idea emerges: What if we were to extend rewards to students not solely based on accurate answers, but also on the effort they invest, even in cases where their actual response might be incorrect? Our study explores the potential impact of this approach on the way information is absorbed and subsequently retained, specifically focusing …


Destined Failure, Chengjun Pan Jun 2023

Destined Failure, Chengjun Pan

Masters Theses

I attempt to examine the complex structure of human communication, explaining why it is bound to fail. By reproducing experienceable phenomena, I demonstrate how they can expose communication structure and reveal the limitations of our perception and symbolization.I divide the process of communication into six stages: input, detection, symbolization, dictionary, interpretation, and output. In this thesis, I examine the flaws and challenges that arise in the first five stages. I argue that reception acts as a filter and that understanding relies on a symbolic system that is full of redundancies. Therefore, every interpretation is destined to be a deviation.


Plant Sentience: Getting To The Roots Of The Problem, Krzysztof Dolega, Savannah Siekierski, Axel Cleeremans May 2023

Plant Sentience: Getting To The Roots Of The Problem, Krzysztof Dolega, Savannah Siekierski, Axel Cleeremans

Animal Sentience

Segundo-Ortin’s (2023) target article invites us to consider the possibility that plants can experience subjectively felt states. We discuss this speculation on the basis of the functional neurobiology of consciousness. We suggest that demonstrating plant sentience would require that we identify not only behaviors analogous to those exhibited by sentient creatures, but also the functional analogues of the mechanisms causing such behaviors. The lack of clear evidence for any kind of integration between self-states, self-movement, environmental states, memory, or affective communication within plants suggests that plant sentience remains an admittedly fascinating, but ultimately merely provocative speculation.


Mapping The Malleable Self: How Self-Views Are Represented And Learned Within The Social Brain, Sasha Carmela Brietzke Jan 2023

Mapping The Malleable Self: How Self-Views Are Represented And Learned Within The Social Brain, Sasha Carmela Brietzke

Dartmouth College Ph.D Dissertations

Humans possess a unique and wide-ranging ability to self-reflect that takes center stage in our everyday cognition. While many people believe their own self to be immutable, different contexts may warp how we perceive the self. The goal of this dissertation is to investigate two lenses through which we may view the self: (1) across time in the past and future, and (2) through the eyes of others via evaluative feedback. In Studies 1-3, I demonstrate that people’s ratings of their own personality become increasingly less differentiated as they consider more distant past and future selves. This effect was preferential …


Multilingualism And Memory: Investigating Possible Differences In The Abilities Of Monolingual And Multilingual College Students, Clara E. Barned Dec 2022

Multilingualism And Memory: Investigating Possible Differences In The Abilities Of Monolingual And Multilingual College Students, Clara E. Barned

Honors Projects

This study investigated whether there is a difference in the memories of monolingual and multilingual undergraduate students using simple memorization tasks. There were 46 participants, 30 of which were monolingual (only knew one language) and 16 of which were multilingual (knew two or more languages). There was found to be no significant difference between the performance of the two groups, with the data generating a p-value of 0.557. This study further suggests related avenues of research and ways in which the study could be improved in the future.


The Distinction Of Logical Decision According To The Model Of The Analysis Of Brain Signals (Eeg), Akeel Abdulkareem Al-Sakaa, Zaid H. Nasralla, Mohsin Hasan Hussein, Saif A. Abd, Hazim Alsaqaa, Kesra Nermend, Anna Borawska Aug 2022

The Distinction Of Logical Decision According To The Model Of The Analysis Of Brain Signals (Eeg), Akeel Abdulkareem Al-Sakaa, Zaid H. Nasralla, Mohsin Hasan Hussein, Saif A. Abd, Hazim Alsaqaa, Kesra Nermend, Anna Borawska

Karbala International Journal of Modern Science

Recently, brain signal patterns have been recruited by researchers in different life activities. Researchers have studied each life activity and how brain signal patterns appear. These patterns could then be generalised and used in different disciplines. In this paper, we study the brain state during decision making in a lottery experiment. An EEG device is used to capture brain signals during an experiment to extract the optimal state for logical decision making. After collecting data, extracting useful information and then processing it, the proposed method is able to identify rational decisions from irrational ones with a success rate of 67%.


The Biological Influence Of Stories & The Importance Of Reading Fiction, Elise N. Good, Katharine Schaab Jul 2022

The Biological Influence Of Stories & The Importance Of Reading Fiction, Elise N. Good, Katharine Schaab

The Kennesaw Journal of Undergraduate Research

Fictional narratives and stories have persisted throughout human history. However, perhaps due to a bias that stories offered nothing more than entertainment for the reader or perhaps that they are not useful outside of the realm of academia, the research within science academia has been lacking in literature on why these narratives have endured. Unfortunately, due to the lack of conversation across disciplines, particularly those of science and literature, this subject has not been thoroughly investigated through an interdisciplinary lens. Within this paper, the goal is to analyze the benefits of fictional narratives through biological, evolutionary, and neuropsychological perspectives. Research …


Cognitive Task Enhancement Through Alpha Neurofeedback, Hannah L. Meyer, Douglas Peterson May 2022

Cognitive Task Enhancement Through Alpha Neurofeedback, Hannah L. Meyer, Douglas Peterson

Honors Thesis

Neurofeedback training has been a recent field of study in neuroscience, as a potential way to increase focus, and possibly boost cognitive performance. Most studies utilize a course of neurofeedback training sessions to find positive results in decreasing ADHD symptoms, depression symptoms, as well as further cognitive changes. In this study, we aim to determine the efficacy of a single session of neurofeedback training in increasing cognitive performance. To do so, we randomly separated 42 volunteers into either a control or experimental group. The experimental group participated in an n-back task both before and after an alpha neurofeedback training session, …


Closed-Loop Brain-Computer Interfaces For Memory Restoration Using Deep Brain Stimulation, David Xiaoliang Wang May 2022

Closed-Loop Brain-Computer Interfaces For Memory Restoration Using Deep Brain Stimulation, David Xiaoliang Wang

Electrical Engineering Theses and Dissertations

The past two decades have witnessed the rapid growth of therapeutic brain-computer interfaces (BCI) targeting a diversity of brain dysfunctions. Among many neurosurgical procedures, deep brain stimulation (DBS) with neuromodulation technique has emerged as a fruitful treatment for neurodegenerative disorders such as epilepsy, Parkinson's disease, post-traumatic amnesia, and Alzheimer's disease, as well as neuropsychiatric disorders such as depression, obsessive-compulsive disorder, and schizophrenia. In parallel to the open-loop neuromodulation strategies for neuromotor disorders, recent investigations have demonstrated the superior performance of closed-loop neuromodulation systems for memory-relevant disorders due to the more sophisticated underlying brain circuitry during cognitive processes. Our efforts are …


Effects Of Music Exposure On Autobiographical Memory In Alzheimer's Patients: A Systematic Review And Meta-Analysis, Gregory Vance May 2022

Effects Of Music Exposure On Autobiographical Memory In Alzheimer's Patients: A Systematic Review And Meta-Analysis, Gregory Vance

Honors Theses

The progression of Alzheimer’s disease is primarily characterized by a loss of memory concerning past events, as well as a lack in ability to create new memories. While this spans across many subsets of memory, such as recognition, recall, and autobiographical memory, there seems to be a lesser impact on musical memory in those with Alzheimer’s. Multiple studies have suggested that exposure to music and introduction of music therapy can even improve other aspects of memory in Alzheimer’s patients. This systematic review and meta-analysis sought to examine the relationship between music exposure and autobiographical memory specifically. A pool of electronic …


Beginnings, Elizabeth Becker Jan 2022

Beginnings, Elizabeth Becker

Dance (MFA) Theses

Researcher Elizabeth Becker uses personal experiences of pregnancy alongside scholarly research on the developmental movement patterns of the human embryo, fetus, and newborn’s first year of life to explore the multiplicity of these movement patterns within and outside the womb. Becker explores the relationship between the fertilization, germinal, embryonic, and fetal stages in relation to a newborn and its mother. These movement patterns within the beginning stages of life are valuable to research because they simulate neurodevelopmental patterns, which help wire the central nervous system in early childhood. These movements also help lay the foundation for sensory-motor development and life-long …

The Amyloid-Β Pathway In Alzheimer’S Disease, Harald Hampel, John Hardy, Kaj Blennow, Christopher Chen, George Perry, Seung Hyun Kim, Victor L. Villemagne, Paul Aisen, Michele Vendruscolo, Takeshi Iwatsubo, Colin L. Masters, Min Cho, Lars Lannfelt, Jeffrey L. Cummings, Andrea Vergallo

School of Medicine Faculty Research

Breakthroughs in molecular medicine have positioned the amyloid-β (Aβ) pathway at the center of Alzheimer’s disease (AD) pathophysiology. While the detailed molecular mechanisms of the pathway and the spatial-temporal dynamics leading to synaptic failure, neurodegeneration, and clinical onset are still under intense investigation, the established biochemical alterations of the Aβ cycle remain the core biological hallmark of AD and are promising targets for the development of disease-modifying therapies. Here, we systematically review and update the vast state-of-the-art literature of Aβ science with evidence from basic research studies to human genetic and multi-modal biomarker investigations, which supports a crucial role of …


Medical Schools Ignore The Nature Of Consciousness At Great Cost, Anoop Kumar Jul 2021

Medical Schools Ignore The Nature Of Consciousness At Great Cost, Anoop Kumar

Journal of Wellness

The essential question of the relationship between consciousness and matter is ignored in medical school curricula, leading to a machine-like view of the human being that contributes to physician burnout and intellectual dissatisfaction. The evidence suggesting that the brain may not be the seat of consciousness is generally ignored to preserve the worldview of the primacy of matter. By investigating new frameworks detailing the nature of consciousness at different levels of hierarchy, we can bring intellectual rigor to a once opaque subject that supports a fundamental reality about our experience: We are human beings, not only human bodies.


Finding Rhythm Through Auditory Imagery: An Approach To Parkinson’S Disease Treatment, Jacqueline Larivee Apr 2021

Finding Rhythm Through Auditory Imagery: An Approach To Parkinson’S Disease Treatment, Jacqueline Larivee

Psychology Student Work

The following research article explores music therapy in the treatment of Parkinson’s Disease (PD). The general interaction between the rhythmic properties of music and motor associated brain areas is discussed at length. These interactions provide a basis for understanding how music therapy can address the rhythmic impairments of the disease. Dance therapy, Musical Sonification, Rhythmic Auditory Stimulation (RAS) are three types of music-based therapies that have been found to be effective in treating the motor symptoms of PD. These therapies may be particularly effective for the PD population because they draw upon musical rhythm as an external pacing cue.While external …


When The Brain Plays A Game: Neural Responses To Visual Dynamics During Naturalistic Visual Tasks, Jason Ki Jan 2021

When The Brain Plays A Game: Neural Responses To Visual Dynamics During Naturalistic Visual Tasks, Jason Ki

Dissertations and Theses

Many day-to-day tasks involve processing of complex visual information in a continuous stream. While much of our knowledge on visual processing has been established from reductionist approaches in lab-controlled settings, very little is known about the processing of complex dynamic stimuli experienced in everyday scenarios. Traditional investigations employ event-related paradigms that involve presentation of simple stimuli at select locations in visual space and discrete moments in time. In contrast, visual stimuli in real-life are highly dynamic, spatially-heterogeneous, and semantically rich. Moreover, traditional experiments impose unnatural task constraints (e.g., inhibited saccades), thus, it is unclear whether theories developed under the reductionist …


Neurocounseling And The Counseling Profession: Integrating Neuroscience Into The Practice Of Counseling, Sherri Clark Dec 2020

Neurocounseling And The Counseling Profession: Integrating Neuroscience Into The Practice Of Counseling, Sherri Clark

Dissertations, Theses, and Projects

Neurocounseling integrates Neuroscience into mental health counseling by using psychoeducation, teaching, and illustrations as well as other forms of therapy (CBT, Interpersonal Psychotherapy, Narrative Therapy, etc.) to assist clients in understanding the neurological basis of many mental and behavioral health concerns. Clients can benefit from Neurocounseling as they gain a more comprehensive understanding of the central nervous system and brain function in connection to the body, cognition, mood, and behaviors, also known as the mind and body connection. Neuroplasticity and neurogenesis allow us to understand the brain’s amazing capability to grow and change. Understanding neuroscience allows for more integrated case …


Using Machine Learning To Conduct A Detailed Behavioral Analysis In An Appetitive Social Learning Task, Thomas Shao May 2020

Using Machine Learning To Conduct A Detailed Behavioral Analysis In An Appetitive Social Learning Task, Thomas Shao

Honors Scholar Theses

Learning by watching others, or observational learning, is important for social development and survival. However, not much is known about the brain mechanisms underlying this type of learning. Since the 1960s, observational learning has been widely studied in humans, but developing and analyzing experiments for animals has been challenging. Here, I explore observational learning using a novel paradigm while performing an analysis that involves tracking the rats using an active learning paradigm called DeepLabCut. In this novel paradigm, customized operant conditioning chambers are used for the rats to observe and learn from another animal repeatedly on multiple trials each day. …


The Effect Of Physical Activity And S-Equol On Neurogenesis In The Hiv-1 Transgenic Rat, Jeremy M. Lapointe Apr 2020

The Effect Of Physical Activity And S-Equol On Neurogenesis In The Hiv-1 Transgenic Rat, Jeremy M. Lapointe

Senior Theses

The aim of this thesis is to investigate the effect of physical activity and the administration of s-equol on rates of neurogenesis in HIV-1 transgenic rats. HIV-1 is a neurodegenerative disease that leads to the wide range of cognitive impairment described as HAND. Neurogenesis is a newly discovered process that involves the birth of new neurons during our adult life within the dentate gyrus of the hippocampus. Therefore, inducing neurogenesis may be a proper therapeutic that can mitigate some of the cognitive destruction seen as a result of HIV-1 infection. Physical activity has shown to increase the rate of neurogenesis …
