Being The Curriculum, Alyssa Hillary Zisk

Ought: The Journal of Autistic Culture

This article is a work of creative non-fiction. Part of the work is my reflections on one systemically awkward experience of introducing my neurodivergence, autism, to my classmates in my graduate program in neuroscience. Part of the work engages with theory and neuroscientific/cognitive findings that I either shared during the presentation or encountered since but would have been relevant to the experience. The two parts are intertwined, because life isn't neatly separable.

Memoir Dataset: Quantifying Image Memorability In Adolescents, Gal Almog, Yalda Mohsenzadeh Aug 2021

Memoir Dataset: Quantifying Image Memorability In Adolescents, Gal Almog, Yalda Mohsenzadeh

Undergraduate Student Research Internships Conference

Every day, humans observe and interact with hundreds of images and scenes; whether it be on a cellphone, on television, or in print. Yet a vast majority of these images are forgotten, some immediately and some after variable lengths of time. Memorability is indeed a property intrinsic to all images that can be extracted, as well as predicted. While memory itself is a process that occurs in the brain of an individual, the concept of memorability is an intrinsic, continuous property of a stimulus that can be both measured and manipulated. We selected images from the MemCat data set that …

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 …

Music And The Brain: A Review Of Neuroscientific And Clinical Applications, Jacqueline Larivee Apr 2021

Music And The Brain: A Review Of Neuroscientific And Clinical Applications, Jacqueline Larivee

Honors Senior Capstone Projects

My research examines the relationship between neuroscience and music, exploring its clinical applications. I extensively review the specific neuroanatomic structures implicated in musical perception. Knowing the function of each brain structure as it relates to musical perception provides insight as to how music is able to elicit certain physical and emotional responses. As music interacts with the human brain, it is also able to provide social, cognitive, and emotional benefits. Given these benefits, my research argues that music is an effective therapeutic intervention for vulnerable populations. I examine the impact of music therapy on preterm infants, hearing impaired individuals, intellectually …

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 …

Neuromodulators promote adaptive behaviors that are often complex and involve concerted activity changes across circuits that are often not physically connected. It is not well understood how neuromodulatory systems accomplish these tasks. Here, we show that the Caenorhabditis elegans NLP-12 neuropeptide system shapes responses to food availability by modulating the activity of head and body wall motor neurons through alternate G-protein coupled receptor (GPCR) targets, CKR-1 and CKR-2. We show ckr-2 deletion reduces body bend depth during movement under basal conditions. We demonstrate CKR-1 is a functional NLP-12 receptor and define its expression in the nervous system. In contrast to …

Late Onset Alzheimer’s Disease is the most common cause of dementia, characterized by extracellular deposition of plaques primarily of amyloid-β (Aβ) peptide and tangles primarily of hyperphosphorylated tau protein. We present data to suggest a noninvasive strategy to decrease potentially toxic Aβ levels, using repeated electromagnetic field stimulation (REMFS) in primary human brain (PHB) cultures. We examined effects of REMFS on Aβ levels (Aβ40 and Aβ42, that are 40 or 42 amino acid residues in length, respectively) in PHB cultures at different frequencies, powers, and specific absorption rates (SAR). PHB cultures at day in vitro 7 (DIV7) treated with 64 …

How The Amino Acid L-Serine Provides Neuroprotection Against L-Bmaa Induced Alzheimer’S Disease, Joseph Cimino Jan 2021

How The Amino Acid L-Serine Provides Neuroprotection Against L-Bmaa Induced Alzheimer’S Disease, Joseph Cimino

Capstone Showcase

More than 6 million people in America are living with Alzheimer’s Disease (AD) and there are currently no cures or treatments. It is time to move on from the ꞵ-amyloid hypothesis and broaden AD research. New research is suggesting that dietary exposure to a cyanobacterial toxin known as L-BMAA is causing neurodegenerative diseases such as AD, Amyotrophic lateral sclerosis (ALS), and Parkinson’s Disease. L-BMAA is misincorporated during protein folding, in place of the proper amino acid, L-Serine. It has been shown that the naturally occurring amino acid, L-Serine, can provide neuroprotection against L-BMAA, but the mechanism by which L-Serine infers …

The Effects Of Rolipram, A Selective Phosphodiesterase Inhibitor, On Immortalized Schwann Cell Proliferation, Akap95 And Cyclin D3 Expression, Kyle P. Kenney, Mary Pistack, Angela Asirvatham Jan 2021

The Effects Of Rolipram, A Selective Phosphodiesterase Inhibitor, On Immortalized Schwann Cell Proliferation, Akap95 And Cyclin D3 Expression, Kyle P. Kenney, Mary Pistack, Angela Asirvatham

Student Research Poster Presentations 2021

Schwann cells are a vital component of the Peripheral Nervous System and aid in the repair of axons following injury. The regulation of Schwann cell growth in vitro is facilitated by heregulin, a neuron-secreted growth factor, and an unknown mitogen that activates the cyclic adenosine monophosphate (cAMP) pathway. The abundance of intracellular cAMP is regulated by a family of enzymes called phosphodiesterases (PDEs). PDE inhibitors such as rolipram have therapeutic potential in various disorders and function by increasing the levels of intracellular cAMP. A-Kinase anchoring proteins (AKAPs), a family of scaffolding proteins that belong to the cAMP/Protein Kinase A (PKA) …

Mapping Of Auditory Cortical Functions Using Electrocorticography, James Robert Swift Jan 2021

Mapping Of Auditory Cortical Functions Using Electrocorticography, James Robert Swift

Legacy Theses & Dissertations (2009 - 2024)

Communication is a dynamic process through which we translate our inner thoughts in such a way that they can be shared with another person. This complex neurological phenomenon is a key predictor of our productivity and health. When our ability to communicate is compromised, our quality of life suffers. Although numerous methods to investigate the neuroscientific underpinnings of human language exist, our understanding of this process remains incomplete. Improving our understanding of where, when, and how auditory cortical activity occurs can enhance diagnostic techniques and improve treatment methods for neurological conditions that can impact auditory processing, such as epilepsy, or …

Estrogen Disruption Of Hypothalamic Neural Activity, Princess Dickson Jan 2021

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 …

Muscarinic Excitation Of Dopamine Neurons In The Ventral Tegmental Area Via Activation Of A Trpc-Like Cation Conductance, Yu Tzu Chen Jan 2021

Muscarinic Excitation Of Dopamine Neurons In The Ventral Tegmental Area Via Activation Of A Trpc-Like Cation Conductance, Yu Tzu Chen

Theses and Dissertations

Dopaminergic (DA) neurons in the ventral tegmental area (VTA) play a crucial role in reward and motivational behaviors, including the development of drug addictions. VTA DA neurons receive excitatory cholinergic inputs from the mesopontine tegmentum. Blockage of the M5 muscarinic receptor in DA neurons has been shown to attenuate drug-induced DA release and abuse-related behaviors, but the molecular mechanism is unknown. In this study, experiments were designed to identify the electrophysiological effects of muscarinic agonism in the modulation of action potential kinetics and firing patterns in VTA DA neurons of mice. Pharmacology of the muscarinic receptor-evoked current was also characterized. …
