Neurocinematics And Empathy: How Cognitive Neuroscience Enhances Our Understanding Of Emotional Responses Of Film, Kira Trinity
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 …
A Picture Worth A Thousand Words: Factors Influencing Disability Accommodations, Alicia E. Martin
A Picture Worth A Thousand Words: Factors Influencing Disability Accommodations, Alicia E. Martin
Cal Poly Humboldt theses and projects
Because not all disabilities look the same it is difficult to label a person with disabilities just by looking at them. Given that our knowledge, attitudes, and perceptions impact how we interpret our world and our willingness to act, people, including professors, may be biased toward providing accommodations for those with easily recognizable disabilities and biased against those with non-recognizable disabilities, and this may impact the disabled person’s ability to learn. This thesis aims to address whether professors’ disability-related attitudes, perceptions of accommodation reasonableness, and willingness to provide accommodations differ when the disability is recognizable (student is pictured in a …
Is The Area Postrema Resistant To The Anesthetic Effects Of Ms-222?, Austin T. Csiszar
Is The Area Postrema Resistant To The Anesthetic Effects Of Ms-222?, Austin T. Csiszar
Cal Poly Humboldt theses and projects
MS-222 is a common fish anesthetic that dampens neural activity by inhibiting neuronal voltage-gated sodium channels (Nav) required for action potentials. Previous experiments conducted by our lab’s primary investigator using fluorescence calcium imaging in zebrafish neurons resulted in the observation that neurons in the area postrema (AP), a circumventricular organ located in the dorsal hindbrain, displayed prominent fluorescence intensity during MS-222 induced sedation. I used the genetically encoded calcium indicator GCaMP6s to conduct fluorescence calcium imaging with the goal of recording neural activity in the larval zebrafish area postrema and optic tectum to compare the anesthetic effects of …
Negative Social Media And Its Influence On Athlete's Performance, Bernd R. Huber
Negative Social Media And Its Influence On Athlete's Performance, Bernd R. Huber
Cal Poly Humboldt theses and projects
This study aimed to investigate the potential impact of negative social media content on athletes' cortisol levels and subsequent performance. The study focused on the change in cortisol levels and differences in free throw performance, based on previous research findings. We hypothesized that negative social media postings would increase the stress experienced by student-athletes, resulting in elevated cortisol levels and decreased performance. Additionally, participants (n = 8) completed a questionnaire to examine the interaction between preexisting fear and the biological stress response. Contrary to expectations, there was no significant change in stress response, and negative postings did not have …
Does Bisphenol-A, An Estrogen-Like Environmental Toxin, Disrupt Expression Of The Neuronal Chloride Exporter Protein During Early Brain Development?, Mayra S. Mendez
Does Bisphenol-A, An Estrogen-Like Environmental Toxin, Disrupt Expression Of The Neuronal Chloride Exporter Protein During Early Brain Development?, Mayra S. Mendez
Cal Poly Humboldt theses and projects
Bisphenol A (BPA), a manufactured compound found in consumer products, is known to adversely affect early brain development by disrupting normal estrogen signaling. Recently, BPA was reported to suppress expression of a gene encoding the neuron-specific chloride ion transporter, KCC2. Human and animal studies show suppressing KCC2 can cause neuronal and behavioral hyperactivity. Therefore, some adverse effects of BPA may be due to KCC2 suppression and consequent neuronal hyperactivity. This study aimed to determine whether BPA exposure during brain development alters KCC2 expression. A secondary purpose was to evaluate whether a new transgenic zebrafish line, KCC2:mCitrine,could be used to track …
Estrogen Disruption Of Hypothalamic Neural Activity, Princess Dickson
Estrogen Disruption Of Hypothalamic Neural Activity, Princess Dickson
Cal Poly Humboldt theses and projects
The brain is highly dependent on the endocrine system for proper neurodevelopment, as it plays a key role in many biological processes. Bisphenol A is a chemical found in plastics that has the potential to mimic the effects of Estrogen in the body, at least weakly. People interact with plastic that contains BPA regularly, and people are at risk for exposure even before being born. The abundance of BPA, along with other exogenous estrogens, makes examining the relationship between early exposure and changes in brain activity imperative. The current study aims to establish a relationship between disrupted estrogen function and …
Neurodegenerative Modeling: Tau Protein, Degradative Pathways, And Gene Expression Profiling Of Human Ipsc-Derived Neural Precursors And Differentiated 3-D Neural Sphere Versus 2-D Monolayer Cultures, Kyle H. Anthoney
Cal Poly Humboldt theses and projects
Human induced pluripotent stem cells offer a model for human brain development and disease by differentiation into brain organoids; however, current neural culture systems lack the microenvironment, neuronal circuits and connectivity, vascular circulation, and immune system that exist in vivo. After differentiation and development of neuronal and non-neuronal cell types within two formats of cell cultures, we can visualize and recapitulate in vivo protein accumulation, gene expression, and degradative processes such as autophagy. Using RNA extraction, purification methods and reverse transcription I compared traditional monolayer cultures and novel 3-D neural sphere cultures via gene expression analysis. This analysis indicated …
Childhood And Trauma: The Effects Of Adverse Childhood Experiences On The Brain, Behavior, And Learning In The Elementary School Classroom, Aeryn Aguilar
Cal Poly Humboldt theses and projects
A variety of studies have been conducted on how trauma, caused by emotional, physical, or verbal abuse, impact children’s lives. Many of the studies which involved observations and assessments were done with the preexisting knowledge that these children had been through a traumatic experience. Instead of looking at behavior of known cases, this study’s goal is to find out whether or not children’s observable behaviors can predict cases of trauma. For example, is acting out or defiance a key sign of trauma or is it part of the typical development for the elementary school-age group? This thesis takes into account …
Test Of Bpa's Estrogenic Effects On Brain Aromatase Expression, Neural Activity, And Locomotive Behavior In Zebrafish Larvae, Ryan J. Mcauley
Test Of Bpa's Estrogenic Effects On Brain Aromatase Expression, Neural Activity, And Locomotive Behavior In Zebrafish Larvae, Ryan J. Mcauley
Cal Poly Humboldt theses and projects
Bisphenol A (BPA) is a well-known endocrine disrupting chemical that mimics the effects of estrogens. Aromatase B (Cyp19a1b) is a brain-specific enzyme that converts testosterone to estrogen and is highly upregulated in response to estrogen receptor activation localized to radial glial cells. During embryonic zebrafish development, there is a small window of time denoted by an increase in neurogenesis and estrogen receptor activity. Previous studies have demonstrated that a low dose BPA exposure (0.1µM) during this window causes hyperlocomotion in larval zebrafish, yet no further explanation for this behavior change has been described. The purpose of this study was to …
The Effects Of Increased Camp Levels On Neuronal Differentiation In Murine Embryonic Stem Cells, And The Creation Of A Crispr-Induced C.1252c>T Point Mutation In The Adcy5 Gene, Elizabeth Zepeda
Cal Poly Humboldt theses and projects
ADCY5-related dyskinesia is a rare movement disorder with early onset in childhood and adolescence. Previous studies linked this disease to various point mutations in the ADCY5 gene. Recent studies show that two of the point mutations cause an increase in cyclic adenosine monophosphate (cAMP) levels. However, it remains unknown how increased levels of cAMP result in the phenotypes associated with this disease. My study examines the effects of increased cAMP levels on neuronal differentiation of mouse embryonic stem cells (mESCs). My experiments demonstrated successful differentiation of mESCs into the dopaminergic neuronal lineage, indicated by the presence of Tuj 1 (a …
