Beyond Neural Data: Cognitive Biometrics And Mental Privacy, Patrick Magee, Marcello Ienca, Nita Farahany

Faculty Scholarship

Innovations in wearable technology and artificial intelligence have enabled consumer devices to process and transmit data about human mental states (cognitive, affective, and conative) through what this paper refers to as ‘‘cognitive biometrics.’’ Devices such as brain-computer interfaces, extended reality headsets, and fitness wearables offer significant benefits in health, wellness, and entertainment through the collection and processing and cognitive biometric data. However, they also pose unique risks to mental privacy due to their ability to infer sensitive information about individuals. This paper challenges the current approach to protecting individuals through legal protections for ‘‘neural data’’ and advocates for a more …

U.S. Public Perceptions Of The Sensitivity Of Brain Data, Shenyang Huang, Umika Paul, Shikhar Gupta, Karan Desai, Melinda Guo, Jennifer Jung, Beatrice Capestany, William D. Krenzer, Dylan Stonecipher, Nita A. Farahany

Faculty Scholarship

As we approach an era of potentially widespread consumer neurotechnology, scholars and organizations worldwide have started to raise concerns about the data privacy issues these devices will present. Notably absent in these discussions is empirical evidence about how the public perceives that same information. This article presents the results of a nationwide survey on public perceptions of brain data, to inform discussions of law and policy regarding brain data governance. The survey reveals that the public may perceive certain brain data as less sensitive than other ‘private’ information, like social security numbers, but more sensitive than some ‘public’ information, like …

The Role Of Semaphorins In Response To Injury In C. Elegans Neurons, Maria Belen Harreguy Alfonso

Dissertations

When neural tissue is injured by trauma, delicate neuronal processes such as axons and dendrites are prone to lesion damage and often disconnect. The molecular, cellular, and circuit mechanisms that underlie the regrowth and reconnection of these processes and the recovery of behavior are major challenges in the fields of neuroscience, regeneration, and resilience. At the molecular and cellular levels, signaling pathways that mediate neuronal growth cone guidance during development can play a role in neuronal regeneration and recovery from injury. One family of signaling proteins involved in this process comprises the highly conserved semaphorins and their receptors, the plexins. …

Assessing Neurobehavioral Deficits And Neuroinflammation Following Rllb In A Transgenic Mouse Model, Aakaash Gosain

Theses

As global conflicts are escalating, military personnel have long faced the constant threat of explosions, heightening the risk of blast-induced traumatic brain injury (bTBI). The recent increase in war conflicts and combat zones worldwide not only puts the military, service members, and police forces at risk but also innocent civilians who are caught in the crossfire. While moderate to severe bTBIs have been extensively studied, the pathology of repeated low-level blasts (rLLB) remains less understood. This research addresses the gap in knowledge regarding the long-term consequences of rLLB injuries in the neural anatomy. A transgenic mouse model was subjected to …

Nucleus Accumbens Core Single Cell Ensembles Bidirectionally Respond To Experienced Versus Observed Aversive Events, Oyku Dinckol, Noah Harris Wenger, Jennifer E Zachry, Munir Gunes Kutlu

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Fear learning is a critical feature of survival skills among mammals. In rodents, fear learning manifests itself through direct experience of the aversive event or social transmission of aversive stimuli such as observing and acting on conspecifics' distress. The neuronal network underlying the social transmission of information largely overlaps with the brain regions that mediate behavioral responses to aversive and rewarding stimuli. In this study, we recorded single cell activity patterns of nucleus accumbens (NAc) core neurons using in vivo optical imaging of calcium transients via miniature scopes. This cutting-edge imaging methodology not only allows us to record activity patterns …

Role Of The Anti-Viral Immune Response In Neural Cell Modulation And Neurological Sequelae Of Childhood Viral Infections, Yashika Kamte

Electronic Theses and Dissertations

Viral infections of the central nervous system (CNS) often result in neurological sequelae and are considered a risk factor for the development of neurological disease. Moreover, the outcomes of a viral infection are largely dependent on the age of the host, with younger hosts developing more profound neuropathology. Perhaps the developing brain coupled with an immature immune system contributes to worse outcomes in the very young. Children suffering from brain infections are more prone to develop enduring neurological impairments even after recovery from the infection. Although majority of the brain growth occurs in utero, neurodevelopment continues throughout the juvenile …

Cardiac Vagal Dysfunction And Ventricular Arrhythmogenesis In Type 2 Diabetes Mellitus After Myocardial Infarction, Dongze Zhang

Theses & Dissertations

Diabetes is the eighth leading cause of death in the United States. Every eight seconds a person dies from diabetes around the world. Among various types of diabetes, type 2 diabetes mellitus (T2DM) is the most common form, representing 90% to 95% of all diabetes populations. The leading cause of mortality and morbidity in T2DM patients is cardiovascular disease, among which acute myocardial infarction (MI)-induced ventricular arrhythmia is the major cause of death in T2DM. Patients with T2DM are two to four times more likely to die from MI than non-diabetic patients. Although well-known therapies including better glycemic control have …

This approach, known as DNA methylation deconvolution or methylation cytometry, offers a standardized and cost-effective method for evaluating cell-type proportions. While this approach has succeeded in discerning cell types in various human tissues like blood, brain, tumors, skin, breast, and buccal swabs, the existing methods have major …

The Role Of Pre- And Perinatal Oxycodone Exposure On Postnatal Brain Development And Behavior: Assessing The Impact On Later Life Brain Injuries In Juvenile Rats, Austin M. Gowen

Theses & Dissertations

There has been a long history of research investigating the role of the gestational environment on later life health and disease. The progressive widespread illicit and prescribed use of opioids in the 21^st century has seen opioids become one of the most significant gestational insults in the last century. The ability of opioids to pass both the placental barrier and blood-brain barrier makes them a particularly dangerous teratogen capable of altering the peripheral physiology, neurobiology, and behavior of affected children. The works herein investigate the impact of a widely prescribed opioid, oxycodone, on developmental neurobiology in the context of …

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 …

Jun Upregulation Drives Aberrant Transposable Element Mobilization, Associated Innate Immune Response, And Impaired Neurogenesis In Alzheimer’S Disease, Chiara Scopa, Samantha Barnada, Maria Cicardi, Mo Singer, Davide Trotti, Marco Trizzino

Farber Institute for Neuroscience Faculty Papers

Adult neurogenic decline, inflammation, and neurodegeneration are phenotypic hallmarks of Alzheimer's disease (AD). Mobilization of transposable elements (TEs) in heterochromatic regions was recently reported in AD, but the underlying mechanisms are still underappreciated. Combining functional genomics with the differentiation of familial and sporadic AD patient derived-iPSCs into hippocampal progenitors, CA3 neurons, and cerebral organoids, we found that the upregulation of the AP-1 subunit, c-Jun, triggers decondensation of genomic regions containing TEs. This leads to the cytoplasmic accumulation of HERVK-derived RNA-DNA hybrids, the activation of the cGAS-STING cascade, and increased levels of cleaved caspase-3, suggesting the initiation of programmed cell death …

Furthermore, this study aims to elucidate the central mechanisms underlying nociceptin induced cardiovascular and renal effects in heart failure. This involves investigating neuronal pathways and …

Effects Of Aerobic Exercise On Rage And Lrp1 In Stz And Hfd Models Of Diabetes: Relationship With Cognitive Function And Aβ Clearance, Corey Joseph Frank

Legacy Theses & Dissertations (2009 - 2024)

The number of individuals with diabetes worldwide has quadrupled since 1980, making diabetes the 4th most common cause of death from non-communicable disease. Since 1975, the number of individuals classified as obese has tripled to 650 million adults, or 13% of the global population (World Health Organization, 2018). Obesity rates in the United States are three times the global average, with 39.8% of adults having a body-mass index of 30 or greater (Hales, 2017). At the same time, in the United States, AD is the sixth most common cause of death, with 5.8 million currently diagnosed, a number that may …

Using A Toxic Aging Coin To Assess Hexavalent Chromium-Induced Neurotoxicity., Samuel Thomas Vielee

Electronic Theses and Dissertations

We are facing an aging crisis, with 20% of the U.S. population projected to be geriatric (65+) by 2030 and live another 40+ years. Age-related diseases accompany a growing geriatric population, emphasizing the need to understand their etiology. Environmental pollutants compound this crisis by: 1) geriatrics are more susceptible, exacerbating age-related diseases and comorbidities, and 2) they accelerate biological aging, inducing age-related diseases at younger ages. We address this crisis using a ‘toxic aging coin’ approach; heads examines how age impacts toxicity, tails examines how chemicals accelerate aging. This thesis applies the heads side for Cr(VI)-induced neurotoxicity across ages. We …

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 …

Deciphering The Role Of Huntingtin In Endosomal Functions, Yue Yu

Dissertations and Theses (Open Access)

Huntington's disease (HD), a neurodegenerative disorder, is a result of an abnormal expansion of CAG trinucleotide repeat encoding an extended polyglutamine (polyQ) tract in the coding region of Huntingtin (HTT) gene. While antisense oligonucleotide (ASO) strategies aimed at lowering mutant HTT levels seemed promising, recent clinical trials were unsuccessful due to worsening patient outcomes in the ASO treatment group compared to the placebo. This may be attributed to potential adverse effects resulting from decreased levels of normal HTT, which could play a pivotal role in brain functions and HD progression. The impact of reduced HTT levels on cellular functions and …

Cortical Representation Of Learning Social Interactions In Freely Moving Non-Human Primates, Melissa Franch

Dissertations and Theses (Open Access)

The motivation and capacity to be social is necessary for human survival. Successful learning of complex, prosocial behavior stems from the ability to perceive and respond to visual cues, such as the body language and facial expressions, from others in our environment. This dependence on visual information to guide social interaction is especially true for humans and non-human primates. Although recent studies in primate neurophysiology discovered neurons that can encode socially relevant variables, like reward and social actions, the underlying neural mechanisms of learning advanced social concepts, such as cooperation, are not well understood. Further, previous work has identified …
