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 …

Historical Trauma Response Scores As A Function Of Unresolved Grief And Substance Use Disorder In American Indian Populations, Andrew R. Saunders

Undergraduate Research Symposium

Abstract

Researchers are interested in the outcomes of interventions, specifically, measuring historical trauma (HT) among American Indian/Alaska Native communities and the long-term distress and substance abuse as a result of historical trauma response (HTR). Previous literature has implicated limitations in the clinical conceptualization of the relationship between intergenerational transfer of HTR and substance abuse. The aim of the current study is to examine treatment efficacy of 50 homosexual, American Indian males randomized to a culturally-adapted juxtaposition of (1) Group Interpersonal Psychotherapy (IPT), (2) Cognitive Processing Therapy (CPT), and (3) Historical Trauma and Unresolved Grief Intervention (HTUG), or (4) waitlisted on …

Investigating Cognitive Impairment In Tdp-43 Mouse Models Of Ftd-Als Using Automated Touchscreens, Keon Coleman

Electronic Thesis and Dissertation Repository

TAR-DNA-binding protein 43 (TDP-43) misfolding and aggregation is a major pathological hallmark of frontotemporal dementia-amyotrophic lateral sclerosis (FTD/ALS). FTD/ALS is characterized by motor and cognitive impairment, with cognitive impairment frequently reported before the onset of classical motor symptoms. Yet, treatment for cognitive decline in FTD/ALS is lacking, and robust cognitive phenotypes related to TDP-43 proteinopathy have not been established for most mouse models of FTD/ALS. Herein, we used automated touchscreen technology to assess executive function (affected in FTD/ALS) in male TDP-43^Q331Klow and ^-G348C FTD/ALS transgenic mice. The touchscreen pairwise visual discrimination task revealed impairments in 4-5-month-old TDP-43^Q331Klow and …

Preliminary Evidence Of The Role Of Medial Prefrontal Cortex In Self-Enhancement: A Transcranial Magnetic Stimulation Study, Birgitta Taylor-Lillquist, Vivek Kanpa, Maya Crawford, Mehdi El Filali, Julia Oakes, Alex Jonasz, Amanda Disney, Julian Keenan

Department of Biology Faculty Scholarship and Creative Works

Humans employ a number of strategies to improve their position in their given social hierarchy. Overclaiming involves presenting oneself as having more knowledge than one actually possesses, and it is typically invoked to increase one’s social standing. If increased expectations to possess knowledge is a perceived social pressure, such expectations should increase bouts of overclaiming. As the medial prefrontal cortex (MPFC) is sensitive to social pressure and disruption of the MPFC leads to decreases in overclaiming, we predicted that transcranial magnetic stimulation (TMS) applied to the MPFC would reduce overclaiming and the effects would be enhanced in the presence of …

Effects Of Chronic Caffeine Administration On Behavioral And Molecular Adaptations To Sensory Contact Model Induced Stress In Adolescent Male Mice, Micheal K. Ibrahim, Mohamed M. Kamal, Rajiv Tikamdas, Roua Aref Nouh, Jiang Tian, Mostafa Sayed

Pharmacy

Previous studies have shown that caffeine attenuates stress-induced mood dysfunction and memory deterioration through neuronal adenosine A2A receptors antagonism. However, whether caffeine exerts this effect through modulating other molecular targets, which interfere with the resilience to social defeat stress in adolescent male mice is unknown. This study was conducted to investigate the role of caffeine in the behavioral responses to social stress induced by the sensory contact model (SCM) and the possible alteration of the gene expression level of Na/K ATPase pump. Adolescent male mice were exposed to SCM for 12 days. Caffeine was administered intraperitoneal daily for 14 days …

Mental Associations And Music Therapy: Including The History Of Associationism And The Neurology Of Associations, Dianna Rose

Expressive Therapies Capstone Theses

Associations are formed in our minds based upon three elements: sensory experience, emotions, and memories. These associations, unique to each individual, dictate thoughts, beliefs, behaviors, and actions. Some are necessary and supportive, while others can be maladaptive. Established associations can be changed, and new associations can be formed, to align with a client’s goals. The literature presents a strong history of associationism, as well as a body of research that demonstrates the neurological processes of how mental associations are formed. There are also studies showing how music activates the brain. However, there is a lack of research which draws direct …

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. …

Effects Of Repeated Intermittent Episodes Of Social Stress On The Acquisition And Extinction Of A Reward-Seeking Task, Nikki Sullivan

Honors Theses

Repeated exposure to stress is known to have a myriad of effects on the brain, contributing to the development of psychiatric disorders, such as anxiety, depression, and drug addiction. For example, rats undergoing repeated social stress develop increased cocaine self-administration. These effects of stress are not well-understood and are related to changes in the brain reward system. This study investigated the effects of repeated social stress on reward-seeking behavior via the acquisition and extinction of a discriminative stimulus (DS) task and on anxiety-like behavior in the elevated plus maze (EPM). Male rats underwent intermittent social defeat (4 sessions in 10 …

The Role Of Dopamine In Decision Making Processes In Drosophila Melanogaster, Michelle C. Bowers

Undergraduate Honors Theses

Understanding the neural processes that mediate decision making is a relatively new field of investigation in the scientific community. With the ultimate goal of understanding how humans decide between one path and another, simpler models such as Drosophila Melanogaster, the common fruit fly, are often utilized as a way of determining the neural circuits involved in these decision-making processes. One of the most important decisions flies make is the decision of where to lay their eggs (oviposit). Choosing the proper substrate upon which to lay eggs is a crucial decision that can ultimately impact their fecundity. This paper investigates the …

Safe Sleep: Developmental Implications For Hospitalized Infants, Katherine Kohlsaat

Senior Honors Projects

The rate at which an infant develops both physically and cognitively is significant during sleep, as this is the time when the entire body can dedicate its efforts to this cause. Parents of healthy infants follow the guidelines set by the American Academy of Pediatrics (AAP) relating to safe sleep, and since their introduction in 1992, the rate of Sudden Infant Death Syndrome (SIDS) has decreased by 40% (Center for Disease Control and Prevention, 2016). However, if an infant has been hospitalized since birth due to necessary invasive procedures such as open-heart surgery, these protocols cannot be initially implemented. Common …

The Role Of Histone Demethylases In Learning And Memory In The Mushroom Body Of Drosophila Melanogaster, Crystal Keung

Electronic Thesis and Dissertation Repository

Intellectual disability (ID) is a neurodevelopmental disorder associated with many epigenetic regulators and chromatin modifying enzymes like histone lysine methyltransferases (KMTs) and demethylases (KDMs). Here, I systematically investigate the role of 7 KDMs: Su(var)3-3, KDM2, Lid, CG2982, UTX, KDM4B, JHDM2, and 1 KMT: trr in the context of learning and memory using Drosophila melanogaster. Genetic knockdown of each gene in the mushroom body (MB) of flies are tested for short- and long-term memory impairment using courtship conditioning. Knockdown of 6 KDMs and trr resulted in memory loss. MB morphology was analyzed to determine potential cause of memory loss. …

Tribal Brains In The Global Village: Deeper Roots Of The Pandemic, Robert Gerlai

Animal Sentience

I briefly recap the messages of the target article by Wiebers & Feigin (2020) and the accompanying peer commentaries about what we learn from the COVID-19 pandemic. Using the rapid evolution of viruses as an example of the importance of prevention, I explore why it is difficult for our species to foresee and prevent unintended global changes resulting from human activity. I end with a discussion about the long-term future, the ultimate problem inherent in our current mindset and the structure of our economy: growth.

A Troop, A Raft, A Bed, Hanna Jane Guendel

Senior Projects Spring 2020

A Troop, a Raft, a Bed tells the interwoven fictional stories of three major animals (the mountain gorilla, the Adélie penguin, and the American eel) and four transitional animals (the white stork, the humpback whale, the common octopus, and the great white shark). The stories are told from the animals' perspectives, and are written with language that considers each animal's unique intelligence, mind, and behavior. These stories seek to communicate how animals around the world may be experiencing the various effects of climate change and global warming.

Does The Direction Of Current Flow Using Transcranial Direct-Current Stimulation (Tdcs) Affect One’S Ability To Perform Motor Tasks?, Zongheng Zhang

Senior Projects Spring 2020

Transcranial direct-current stimulation (tDCS), is a non-invasive, painless brain stimulation treatment that uses direct electrical currents to stimulate specific parts of the brain. This is achieved by placing two electrodes--one positive (the anode) and one negative (the cathode)--on the scalp and running current across them. Altering the cortical excitability in this manner has been associated with changes in a variety of cognitive and motor tasks, those thought to be controlled by the underlying regions. While most of the existing literature has focused on the effects of placing the anode over the target region (often benefitting the associated performance), there is …

Whether Invertebrates Are Sentient Matters To Bioethics And Science Policy, Michael L. Woodruff

Animal Sentience

Mikhalevich & Powell provide convincing empirical evidence that at least some invertebrates are sentient and hence should be granted moral status. I agree and argue that functional markers should be the primary indicators of sentience. Neuroanatomical homologies provide only secondary evidence. Consensus regarding the validity of these functional markers will be difficult to achieve. To be effective in practice, functional markers of sentience will have to be tested and accepted species by species to overcome the implicit biases against extending moral status to invertebrates.
