2020-Current year OA Pubs

The aim of this White Paper is to establish a foundational framework for research, technological development, and regulation in the emerging field of stem cell-based embryo models (SCBEMs). These models, generated from Pluripotent Stem Cells, are designed to recapitulate essential events in early stages of human development. They have the potential to illuminate the early stages of embryo development and implantation and hold promise as an avenue to address global health challenges, including infertility and pregnancy loss, congenital, neonatal and adult conditions, and the need for organ transplants. While SCBEMs are not a substitute for human embryos, their tractability for …

Our protocol outlines methodological details for transcardiac perfusion, fixation, decalcification, paraffin processing, and a sample co-embedding strategy facilitating anatomically consistent and simultaneous sectioning of …


Neural Plasticity Across Hormonal States In Females: From Modulator To Dynamic Regulator, Takahiro Sasaki, Christine Nwaigwe, Sayaka Inoue Jun 2026

Neural Plasticity Across Hormonal States In Females: From Modulator To Dynamic Regulator, Takahiro Sasaki, Christine Nwaigwe, Sayaka Inoue

2020-Current year OA Pubs

Ovarian sex steroid hormones play a critical role in regulating fertility. In addition, these hormones influence behavior and mood across the lifespan in females. Converging evidence from rodent studies and human neuroimaging shows that ovarian hormones dynamically regulate neuronal excitability, synaptic efficacy, and structural remodeling across menstrual/estrous cycles, puberty, and reproductive aging. Estrogen and progesterone reorganize network dynamics and gate plasticity eligibility rather than uniformly scaling synaptic strength, with additional contributions from glia, the extracellular matrix, and neurosteroid signaling. Here we synthesize recent cross-scale advances that link structural and functional changes to cellular and circuit mechanisms, and relate these dynamics …

Brain and Mind Institute

Background. Safety supports psychological wellbeing and potentially shapes brain aging yet existing scales overlook cumulative lifespan safety experiences.

Methods. To address this gap, we developed and validated the Lifetime Sense of Safety (LSS) scale in Kenyan adults. The LSS uses visual analog scaling with a red-to-green color gradient to retrospectively rate felt safety across life stages and settings. We evaluated scale psychometrics and associations with social determinants of health and indicators of brain health.

Results. The LSS shows adequate internal consistency and test-retest reliability, with two distinct but correlated factors representing childhood and adulthood safety. Women and …

An Obligatory Role For Agrp Neurons In Maintaining Body Temperature During Time-Restricted Feeding, Cunjin Su, Jing Cai, Yuanzhong Xu, Benjamin R Arenkiel, Qingchun Tong

The Brown Foundation: Institute of Molecular Medicine

Homeotherms maintain a steady body temperature through thermoregulation, a process critical for survival during fasting, in which the brain has to defend energy-costly body temperature while reducing energy expenditure to conserve energy reserve; however, the neural basis for defending body temperature remains unclear. Here, we demonstrated that AgRP neuron lesion led to lethality during time-restricted feeding on chow but not on HFD, and caused no obvious impact on HFD-induced obesity or obesity-reducing responses to glucagon-like peptide-1 receptor agonism. The lesion disrupted adaptive feeding behaviors during time-restricted feeding and reduced motivational feeding on chow. Notably, the lethality was caused by hypothermia …

Understanding And Enhancing Suicide Prevention Strategies In The Military: The Roles Of Culture, Leadership, And Command Climate, Kelly Johanna Pires

Dissertations

Military service members are shaped and molded to fit a military culture that emphasizes mission readiness and continuous preparedness. Countless hours are spent training for various situations that can arise. Many trainings are geared toward worst-case scenarios that can cause an increase in stressors and traumatic events. They are expected to demonstrate resilience and overcome adversity to remain mission-ready. This expectation to be mission-ready creates the space for mental health difficulties as well as stigma and avoidance of help-seeking behaviors. In many cases, the desire to stay mission-ready creates a barrier for conversations around mental health. The military emphasizes qualities …

A Predictive Coding Account Of Spatial Working Memory Following Prophylactic Levetiracetam Administration Prior To Traumatic Brain Injury, Omeima Mutwali

Dissertations, Theses, and Capstone Projects

Traumatic brain injury (TBI) symptom prevention and remediation is an important area of research that would benefit vulnerable groups, including active-duty and veteran soldiers. These patients can sustain penetrative forces in fields of combat or in training, which result in focal lesions that trigger inflammatory and degenerative processes in the brain. Both primary and secondary injuries are associated with changes to cognition, behavior and affective state. This disease poses increased risk of epileptogenesis, as well. Given these outcomes, prior research has evaluated levetiracetam (LEV) as a prophylactic treatment for seizures, cognitive deficits and negative emotionality. LEV acts as a presynaptic …


Enhancing Ecological Validity In Speech-In-Noise Testing: Integrating Virtual Reality For A Multisensory Audiological Experience, Paulina Lee Jun 2026

Enhancing Ecological Validity In Speech-In-Noise Testing: Integrating Virtual Reality For A Multisensory Audiological Experience, Paulina Lee

Dissertations, Theses, and Capstone Projects

Despite the remarkable advances in hearing healthcare technology, the speech recognition tests used in routine clinical audiological assessment have remained essentially the same for decades.  Monosyllabic word recognition tests in quiet, such as the Northwestern University Auditory Test No. 6 (NU-6; Tillman & Carhart, 1966), have served as the audiology field’s default measure of speech understanding.  Modern speech-in-noise (SIN) tests, such as the QuickSIN (Killion et al., 2004), have emerged, yet they remain auditory-only, leaving an unignorable gap between what clinical tests measure and how patients communicate in daily life.  The present study examined whether pairing a standard SIN test …

BACKGROUND: Flow diversion is effective for unruptured distal anterior cerebral artery (DACA) aneurysms, yet comparative data between the Silk Vista Baby (SVB) and Pipeline Embolization Device (PED) in this challenging territory remain scarce.

METHODS: We conducted a retrospective multicenter study using the CRETA Registry, including consecutive patients with unruptured DACA aneurysms treated with SVB or PED. The primary endpoint was complete angiographic occlusion (O'Kelly-Marotta grade D). Secondary outcomes included procedural characteristics, clinical outcome (modified Rankin Scale), and complications. Overlap weighting was applied to account for non-randomized treatment allocation. Predictors of occlusion were explored using penalized logistic regression. A sensitivity analysis …


Mathematical Models Of Multisensory Detection And Decision-Making, Rebecca M. Brady Jun 2026

Mathematical Models Of Multisensory Detection And Decision-Making, Rebecca M. Brady

Doctoral

The brain seamlessly integrates signals from multiple sensory modalities to interpret the world efficiently. By using information from various senses, the brain can enhance its ability to detect and respond to stimuli more quickly and accurately. However, combining sensory cues from multiple modalities is only sometimes beneficial as it may lead to illusions and reduced behavioural performance. Behavioural and electrophysiological experiments have revealed that detection and decision-making strategies for multisensory cues evolve throughout human development and ageing. Additionally, studies have demonstrated that maladaptive multisensory processing is a key indicator of a proclivity to falls in older adults and individuals with …

From Transcriptome To Function: Multimodal Characterization Of Transcriptionally Defined Ventral Tegmental Area Dopamine Neurons, Natalie Dalton Fitzgerald

ETDs from 2020-2029

Substance use disorder is a complex neurobiological disease characterized by impaired control over drug taking and drug seeking. Drugs of abuse exert their reinforcing effects largely through dopaminergic (DAergic) projections from the ventral tegmental area (VTA) to the nucleus accumbens, where all drugs of abuse increase DA transmission. Beyond reward processing and reward learning, the VTA contributes to a range of psychiatric conditions, including schizophrenia and attention-related disorders. Although DA signaling has long been a major focus of addiction research, recent transcriptomic studies have revealed substantial heterogeneity of cell types within the VTA. Previous work from our lab identified two …

Characterizing The Role Of The Paraventricular Nucleus Of The Thalamus D2r+ Neurons In Interoceptive Predictions, Briana Machen Jun 2026

Characterizing The Role Of The Paraventricular Nucleus Of The Thalamus D2r+ Neurons In Interoceptive Predictions, Briana Machen

ETDs from 2020-2029

Interoceptive predictions are internal models through which the brain anticipates future bodily states based on past experiences and environmental cues. Under healthy conditions, these predictions allow organisms to anticipate physiological needs and proactively adjust behavior to maintain homeostasis. When these processes become dysregulated, however, environmental cues can trigger maladaptive physiological responses. Although interoceptive prediction is increasingly recognized as a key mechanism underlying adaptive behavior, the neuronal circuits responsible for generating these predictions remain poorly understood. The paraventricular nucleus of the thalamus (PVT) receives convergent inputs from brain regions involved in processing both interoceptive signals and exteroceptive cues, positioning it to …

Cells communicate through ligand-receptor (LR) signaling interactions, but identifying when and where these interactions are active remains challenging. We developed CytoSignal to infer the locations and dynamics of cell-cell communication at cellular resolution from spatial transcriptomic data. Here we show that our cellular resolution, spatially resolved signaling scores enable several important analyses-identifying spatial gradients in signaling strength, quantifying the locations of contact-dependent and diffusible interactions, detecting signaling-associated genes and identifying differential signaling across multisample data. Additionally, we can predict the temporal dynamics of a signaling interaction at each spatial location. We experimentally validate our results in situ by proximity ligation …


Independent And Combined Effects Of Early-Life Iron Deficiency And Antibiotic Exposure On Growth And Hematological Outcomes In A Piglet Model, Ginger M. Fitzpatrick Jun 2026

Independent And Combined Effects Of Early-Life Iron Deficiency And Antibiotic Exposure On Growth And Hematological Outcomes In A Piglet Model, Ginger M. Fitzpatrick

Master's Theses

Iron deficiency (ID) affects over 2 billion individuals globally. Children under 5 are at increased risk of ID due to rapid growth and are especially vulnerable to its negative consequences because of iron’s essential role in cognitive development and immune maturation. ID is the leading cause of iron deficiency anemia (IDA), with IDA affecting approximately 40% of children in this age group. Antibiotic (abx) exposure is also prevalent during early life and may disrupt growth and through gut dysbiosis, with increasing use posing additional risk in younger populations. Geographically, there is overlap in regions with high anemia prevalence and those …

Assessing Aflatoxin Knowledge, Perceptions, And Related Practices, In A Rural Coastal Community: A Population-Based Cross-Sectional Survey, Rosebella Iseme, Joseph Abuodha, Anthony Ngugi, Innocent Abayo, Mansoor Saleh

Population Health, East Africa

Background

Aflatoxin contamination is a significant yet under-addressed food safety challenge in low-resource settings, driven by a complex interplay of environmental, agricultural, and socio-economic factors. Limited access to agricultural inputs, inadequate post-harvest handling and storage, and weak regulatory enforcement alongside food scarcity and climate change heighten the risk of contamination and exposure. Human exposure is associated with serious health consequences, including hepatocellular carcinoma, immune suppression, and childhood stunting. Although aflatoxin is increasingly recognized as a global food safety concern, little is known about community-level knowledge, risk perceptions, and preventive practices. This study examined household heads’ awareness, perceptions, and behaviours related …

Climate-Driven Stochastic Modelling Of Crimean-Congo Haemorrhagic Fever Transmission In Uganda, P. G. Kpatchana, J. Aduda, K. M. Agboka

All Peer-Reviewed Publications

Crimean-Congo haemorrhagic fever (CCHF) is a climate-sensitive tick-borne zoonosis that remains a significant public health concern in Uganda, where temperature and vapour pressure deficit influence tick ecology and consequently disease transmission. This study aimed to develop and analyse a climate-driven stochastic model for CCHF transmission among ticks, livestock, and humans under environmental variability in Uganda. A compartmental transmission model was formulated and extended into a stochastic differential equation framework by incorporating multiplicative environmental noise. Climate-dependent tick recruitment, development, and mortality were parameterized using district-level temperature and vapour pressure deficit data to capture spatial heterogeneity in transmission risk. Theoretical analyses based …
