Increased Neural Activity In The Bed Nucleus Of The Stria Terminalis Of Uninfected Canaries After Observation Of Infected Conspecifics, Madeleine Chang, Sophia Santangelo, Devon Comito, Bennett Hardy, Patricia C. Lopes

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Recent evidence suggests that the immune system may be upregulated in anticipation of pathogen exposure, yet the neural mechanisms that respond to and signal impending infection risk remain poorly understood. We investigated neural responses to infection risk in uninfected hosts observing infected conspecifics, using the canary (Serinus canaria domestica)—Mycoplasma gallisepticum host–parasite system. We focused on five brain regions of interest, comprising three nodes of the social decision-making network—preoptic area, bed nucleus of the stria terminalis (BNST) and hippocampus—a stress modulatory region (paraventricular nucleus) and a visual processing region (nucleus rotundus). After 1 h of observing infected canaries, …

Effects Of Nicotine On Dopamine Signaling In Sprague Dawley Rats, Dominik Sretenovic, Kyle A. Marsh, Sabin Mulch, Gahnan Schaff, Anthony Jones, Sukhman Bains, David Daberkow

2025 Symposium

Nicotine influences dopamine (DA) release in the nucleus accumbens, a brain region associated with reward processing and addiction. This study examined nicotine’s effects on DA signaling using fast-scan cyclic voltammetry (FSCV) in anesthetized rats. Electrodes were implanted to stimulate DA release in the medial forebrain bundle and record signals in the ventral striatum. After administering saline or nicotine, DA levels were monitored in real-time, and electrode placement was later verified through histological analysis. Saline-treated rats showed minor DA fluctuations, with a peak signal detected at 50 minutes, while technical difficulties prevented complete nicotine data collection. However, previous experiments indicated significantly …

Neuroinflammatory Signaling And Immune Cell Infiltration Differ In Brains Of Rats Exposed To Space Radiation And Social Isolation, Austin M. Adkins, Zachary N. M. Luyo, Alea F. Boden, Riley S. Heerbrandt, Richard A. Britten, Laurie L. Wellman, Larry D. Sanford

Center for Integrative Neuroscience and Inflammatory Diseases (CINID) Faculty Publications

Astronauts on the proposed Mars missions will be exposed to extended periods of social isolation (SI) and space radiation (SR). SI and SR-induced immune dysregulation can result in persistent neuroinflammation and neuronal damage which could negatively impact an astronaut’s health and ability to maintain adequate levels of performance. The synergistic effects of combined SI and SR on immune system functionality and the brain remain unknown. Determining how single and combined inflight stressors modulate the immune system is crucial for fully understanding pathways impacting astronaut health and performance. We used ground-based analogs of SI and SR in rodent models to investigate …

A Comparative Analysis Of Perineuronal Nets In Trout And Zebrafish Models, Adnan Alyan

Cal Poly Humboldt theses and projects

Perineuronal nets (PNNs) are specialized extracellular matrix structures that surround certain types of neurons in the central nervous system. Research from the past few decades has cemented PNNs as an integral player in the closure and onset of critical periods, memory modulation, and neural plasticity. These effects are thought to occur when PNNs form around a neuron and structurally stabilize its synaptic connections. PNNs have been directly linked to behavioral changes, making them of interest to psychologists as well as neuroscientists. Several PNN components, such as Hapln1 and aggrecan such as have been found in zebrafish, a teleost fish (Kang …

Are Embryos Or Fetuses Brain Dead? Implications For The Abortion Debate, Greer Donley

Pace Law Review

Most state abortion definitions exclude the removal of a dead fetus, attempting to distinguish miscarriage and abortion care. But what does “dead” mean at the earliest stages of potential life? There is a consensus at the end of life that death not only encompasses the cessation of cardiac activity, but also brain death. This symposium essay considers whether life can only begin with the emergence of brain life and if so, how that might impact the abortion debate. The most rudimentary brain waves cannot be detected in an embryo before roughly the eighth week of pregnancy; the capacity for feeling …

Neuroscience Faculty Publications

Aging dogs serve as a valuable preclinical model for Alzheimer's disease (AD) due to their natural age-related development of β-amyloid (Aβ) plaques, human-like metabolism, and large brains that are ideal for studying structural brain aging trajectories from serial neuroimaging. Here we examined the effects of chronic treatment with the calcineurin inhibitor (CNI) tacrolimus or the nuclear factor of activated T cells (NFAT)-inhibiting compound Q134R on age-related canine brain atrophy from a longitudinal study in middle-aged beagles (36 females, 7 males) undergoing behavioral enrichment. Annual MRI was analyzed using modern, automated techniques for region-of-interest-based and voxel-based volumetric assessments. We found that …

Pediatric Neurotropic Infection Alters Synaptic Development In The Developing Brain, Anuoluwapo Grace Fadare, Yashika S. Kamte, Manish N. Chandwani, Lauren A. O'Donnell

Rowan-Virtua Research Day

Many neurotropic viruses cause more significant pathology in younger hosts as their brains are still developing. This experiment asked how central nervous system (CNS) viral-infections affect the development of synapses in the pediatric brain during infection and post-infection. Synaptogenesis is at its peak in pediatric mice (10 days old) and we hypothesized that a neurotropic infection could disrupt synaptic proteins. We used a transgenic mouse model where measles virus (MV) infects only mature neurons, leading us to question whether synapses were impacted. We examined synaptic markers in the cerebellum and hippocampus in MV-infected and uninfected mice 9 days and 90 …

Stable, Neuron-Specific Gene Expression In The Mouse Brain, Osama Ahmed, Kingsley M. Ekumi, Francesco V. Nardi, Gulimiheranmu Maisumu, Khaled Moussawi, Eric D. Lazartigues, Bo Liang, Abraam M. Yakoub

School of Medicine Faculty Publications

Gene delivery to, and expression in, the mouse brain is important for understanding gene functions in brain development and disease, or testing gene therapies. Here, we describe an approach to express a transgene in the mouse brain in a cell-type-specific manner. We use stereotaxic injection of a transgene-expressing adeno-associated virus into the mouse brain via the intracerebroventricular route. We demonstrate stable and sustained expression of the transgene in neurons of adult mouse brain, using a reporter gene driven by a neuron-specific promoter. This approach represents a rapid, simple, and cost-effective method for global gene expression in the mouse brain, in …

Automatic Hemorrhage Segmentation In Brain Ct Scans Using Curriculum-Based Semi-Supervised Learning, Solayman H. Emon, Tzu-Liang (Bill) Tseng, Michael Pokojovy, Peter Mccaffrey, Scott Moen, Md Fashiar Rahman

Mathematics & Statistics Faculty Publications

One of the major neuropathological consequences of traumatic brain injury (TBI) is intracranial hemorrhage (ICH), which requires swift diagnosis to avert perilous outcomes. We present a new automatic hemorrhage segmentation technique via curriculum-based semi-supervised learning. It employs a pre-trained lightweight encoder-decoder framework (MobileNetV2) on labeled and unlabeled data. The model integrates consistency regularization for improved generalization, offering steady predictions from original and augmented versions of unlabeled data. The training procedure employs curriculum learning to progressively train the model at diverse complexity levels. We utilize the PhysioNet dataset to train and evaluate the proposed approach. The performance results surpass those of …

Howard, Masahiro Yamada, Marcia Dovel, Rie Leverett, Alexander Hill, Kenneth A. Manlapaz, David O. Keyser, Rene S. Hernandez, Sheilah S. Rowe, Walter S. Carr, Michael S. Roy, Christopher K. Rhea

Rehabilitation Sciences Faculty Publications

Subconcussive blast exposure has been shown to alter neurological functioning. However, the extent to which neurological dysfunction persists after blast exposure is unknown. This longitudinal study examined the potential short- and long-term effects of repeated subconcussive blast exposure on neuromotor performance from heavy weapons training in military personnel. A total of 214 participants were assessed; 137 were exposed to repeated subconcussive blasts and 77 were not exposed to blasts (controls). Participants completed a short stepping-in-place task while an Android smartphone app placed on their thigh recorded movement kinematics. We showed acute suppression of neuromotor variability 6 h after subconcussive blast …

Anesthetized Animal Experiments For Neuroscience Research, Shin Nagayama, Sanae Hasegawa-Ishii, Shu Kikuta

Faculty, Staff and Student Publications

Brain research has progressed with anesthetized animal experiments for a long time. Recent progress in research techniques allows us to measure neuronal activity in awake animals combined with behavioral tasks. The trends became more prominent in the last decade. This new research style triggers the paradigm shift in the research of brain science, and new insights into brain function have been revealed. It is reasonable to consider that awake animal experiments are more ideal for understanding naturalistic brain function than anesthetized ones. However, the anesthetized animal experiment still has advantages in some experiments. To take advantage of the anesthetized animal …

Combined 3d Bioprinting And Tissue-Specific Ecm System Reveals The Influence Of Brain Matrix On Stem Cell Differentiation, Martina Zamponi, Peter A. Mollica, Yara Khodour, Julie S. Bjerring, Robert D. Bruno, Patrick C. Sachs

School of Medical Diagnostics & Translational Sciences Publications

We have previously shown that human and murine breast extracellular matrix (ECM) can significantly impact cellular behavior, including stem cell fate determination. It has been established that tissue-specific extracellular matrix from the central nervous system has the capacity to support neuronal survival. However, the characterization of its influence on stem cell differentiation and its adaptation to robust 3D culture models is underdeveloped. To address these issues, we combined our 3D bioprinter with hydrogels containing porcine brain extracellular matrix (BMX) to test the influence of the extracellular matrix on stem cell differentiation. Our 3D bioprinting system generated reproducible 3D neural structures …

Atlas-Based Shared-Boundary Deformable Multi-Surface Models Through Multi-Material And Two-Manifold Dual Contouring, Tanweer Rashid, Sharmin Sultana, Mallar Chakravarty, Michel Albert Audette

Electrical & Computer Engineering Faculty Publications

This paper presents a multi-material dual “contouring” method used to convert a digital 3D voxel-based atlas of basal ganglia to a deformable discrete multi-surface model that supports surgical navigation for an intraoperative MRI-compatible surgical robot, featuring fast intraoperative deformation computation. It is vital that the final surface model maintain shared boundaries where appropriate so that even as the deep-brain model deforms to reflect intraoperative changes encoded in ioMRI, the subthalamic nucleus stays in contact with the substantia nigra, for example, while still providing a significantly sparser representation than the original volumetric atlas consisting of hundreds of millions of voxels. The …

Planning System For The Optimization Of Electric Field Delivery Using Implanted Electrodes For Brain Tumor Control, Erin Iredale, Brynn Voigt, Adam Rankin, Kyungho W Kim, Jeff Z Chen, Susanne Schmid, Matthew O Hebb, Terry M Peters, Eugene Wong

Anatomy and Cell Biology Publications

BACKGROUND: The use of non-ionizing electric fields from low-intensity voltage sources (< 10 V) to control malignant tumor growth is showing increasing potential as a cancer treatment modality. A method of applying these low-intensity electric fields using multiple implanted electrodes within or adjacent to tumor volumes has been termed as intratumoral modulation therapy (IMT).

PURPOSE: This study explores advancements in the previously established IMT optimization algorithm, and the development of a custom treatment planning system for patient-specific IMT. The practicality of the treatment planning system is demonstrated by implementing the full optimization pipeline on a brain phantom with robotic electrode implantation, postoperative imaging, and treatment stimulation.

METHODS: The integrated planning pipeline in 3D Slicer begins with importing and segmenting patient magnetic resonance images (MRI) or computed tomography (CT) images. The segmentation process is manual, followed by a semi-automatic smoothing step that allows …

Impact Forces And Patterns Of Axonal Injury Differ Between Two Models Of Tbi, Edward Lai, David M Devilbiss

Rowan-Virtua Research Day

Traumatic brain injury (TBI) affects approximately 3.8 million Americans a year and results in complex neuropathological and neurocognitive sequelae. Animal models of TBI attempt to replicate the impact forces and pathology of injury in humans. However, in these models, the forces generated at the time of impact are poorly understood. Nonetheless, a variety of shear and strain forces generated at the time of impact can produce diffuse axonal injury. Injury to axons and neurons across a variety of brain regions resulting from axonal injury underlies the cognitive and behavioral impairments observed after TBI. Three critical brain regions, the corpus callosum …

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.

Neurophysiology Of Space Medicine: A Literature Review, Jose R. Velasquez

MEDI 9331 Scholarly Activities Clinical Years

Space medicine is becoming an essential and expanding clinical discipline. Acquiring a deeper and complete picture understanding of the multi-systemic response due to space on human health and function is essential to ensure the success of future space exploration. A comprehensive review of the literature was performed using PubMed and focused on the current neurophysiologic findings of the central nervous system’s response to space. Ground-based analogues, which mimic the effects of microgravity, and actual spaceflight studies have been used to analyze these physiologic adaptations to space. Overall, cerebellar, sensorimotor and vestibular brain regions seem to be affected the most. Through …

Virtual Dissection Of White Matter Tracts In A Human Brain Using Applied Game Design And Virtual Reality Imaging, Basil Lim, Anurag Nasa, Nicola Carswell, Elena Roman, Malia Kissner, Darren W. Roddy, Veronika O'Keane, James Carswell

Other

Visualisation of neural tracts in the human brain has previously been accomplished using two dimensional (2D) representational formats. In most cases, pre-operative visualisation is through the medium of 2D MRI image slices, representing coordinates in the brain through a combination of axial, sagittal, and coronal orthographic viewpoints. Software such as ExploreDTI can visualise off-axis viewpoints, however this method is limited to 2.5D image representations. The use of such 2D representations can require significant training in order to contextualise real-world 3D positions and accurately locate and identify neural tract pathways in the brain. Utilising anonymised tract data and advanced neuroimaging technologies …

Functional Brain Activation Changes Associated With Practice In Delaying Smoking Among Moderate To Heavy Smokers: Study Protocol And Rationale Of A Randomized Trial (Cope)., Andrew T. Fox, Delwyn Catley, Kimber P. Richter, Edward F. Ellerbeck, Morgan G. Brucks, Vlad B. Papa, Laura E. Martin

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Most smokers struggle to overcome tobacco addiction. Neuroscientific models of addiction emphasize the importance of brain regions associated with cognitive control and reward to understand the cycle of addiction and relapse. During an attempt at abstinence, the cognitive control system appears to be underpowered to override the heightened reward system of the addicted brain. Thus, one neural target for treatment is to strengthen the cognitive control system. It may be possible to improve the functioning of the cognitive control system via deliberate practice.

METHODS/DESIGN: This study will determine the effects of practicing delaying smoking on brain and behavioral measures …

Bilateral Carotid Artery Stenosis Causes Unexpected Early Changes In Brain Extracellular Matrix And Blood-Brain Barrier Integrity In Mice, Jill M. Roberts, Michael E. Maniskas, Gregory J. Bix

Neuroscience Faculty Publications

Bilateral carotid artery stenosis (BCAS) is one experimental model of vascular dementia thought to preferentially impact brain white matter. Indeed, few studies report hippocampal and cortical pathology prior to 30 days post-stenosis; though it is unclear whether those studies examined regions outside the white matter. Since changes in the blood-brain barrier (BBB) permeability precede more overt brain pathology in various diseases, we hypothesized that changes within the BBB and/or BBB-associated extracellular matrix (ECM) could occur earlier after BCAS in the hippocampus, cortex and striatum and be a precursor of longer term pathology. Here, C57Bl/6 mice underwent BCAS or sham surgeries …

Internal Medicine Faculty Publications

Central nervous system (CNS) involvement occurs in 5 to 10% of individuals with disseminated histoplasmosis. Most experience has been derived from small single center case series, or case report literature reviews. Therefore, a larger study of central nervous system (CNS) histoplasmosis is needed in order to guide the approach to diagnosis, and treatment.

A convenience sample of 77 patients with histoplasmosis infection of the CNS was evaluated. Data was collected that focused on recognition of infection, diagnostic techniques, and outcomes of treatment.

Twenty nine percent of patients were not immunosuppressed. Histoplasma antigen, or anti-Histoplasma antibodies were detected in the …

Generation Of Organ-Conditioned Media And Applications For Studying Organ-Specific Influences On Breast Cancer Metastatic Behavior, Matthew M. Piaseczny, Graciella M. Pio, Jenny E. Chu, Ying Xia, Kim Nguyen, David Goodale, Alison Allan

Anatomy and Cell Biology Publications

Breast cancer preferentially metastasizes to the lymph node, bone, lung, brain and liver in breast cancer patients. Previous research efforts have focused on identifying factors inherent to breast cancer cells that are responsible for this observed metastatic pattern (termed organ tropism), however much less is known about factors present within specific organs that contribute to this process. This is in part because of a lack of in vitro model systems that accurately recapitulate the organ microenvironment. To address this, an ex vivo model system has been established that allows for the study of soluble factors present within different organ microenvironments. …

“My Logic Is Undeniable”: Replicating The Brain For Ideal Artificial Intelligence, Samuel C. Adams

Senior Honors Theses

Alan Turing asked if machines can think, but intelligence is more than logic and reason. I ask if a machine can feel pain or joy, have visions and dreams, or paint a masterpiece. The human brain sets the bar high, and despite our progress, artificial intelligence has a long way to go. Studying neurology from a software engineer’s perspective reveals numerous uncanny similarities between the functionality of the brain and that of a computer. If the brain is a biological computer, then it is the embodiment of artificial intelligence beyond anything we have yet achieved, and its architecture is advanced …

Development And Validation Of A Sensitive Uplc-Ms/Ms Method For The Quantitation Of [13c]Sucrose In Rat Plasma, Blood, And Brain: Its Application To The Measurement Of Blood-Brain Barrier Permeability, Mohammad K. Miah, Ulrich Bickel, Reza Mehvar

Pharmacy Faculty Articles and Research

Accurate and reproducible measurement of blood-brain barrier (BBB) integrity is critical in the assessment of the pathophysiology of the central nervous system disorders and in monitoring therapeutic effects. The widely-used low molecular weight marker [14C]sucrose is non-specific in the absence of chromatographic separation. The purpose of this study was to develop and validate a sensitive and reproducible LC-MS/MS method for the analysis of stable isotopemodified [13C12]sucrose in brain, plasma, and blood to determine BBB permeability to sucrose. After addition of internal standard (IS, [13C6]sucrose), the marker and IS were recovered from diluted rat blood, plasma, and brain homogenate by protein …

Neuron-Based Heredity And Human Evolution, Don M. Gash, Andrew S. Deane

Neuroscience Faculty Publications

It is widely recognized that human evolution has been driven by two systems of heredity: one DNA-based and the other based on the transmission of behaviorally acquired information via nervous system functions. The genetic system is ancient, going back to the appearance of life on Earth. It is responsible for the evolutionary processes described by Darwin. By comparison, the nervous system is relatively newly minted and in its highest form, responsible for ideation and mind-to-mind transmission of information. Here the informational capabilities and functions of the two systems are compared. While employing quite different mechanisms for encoding, storing and transmission …

The Effects Of Mindfulness Meditation On Rumination In Depressed People, Rachel A. Sluder

Honors Theses and Capstones

Mindfulness meditation is a practice of focus, awareness, and non-judgmental acceptance of one's thoughts (Deyo et al., 2009; Kenny et al., 2007). Rumination is a maladaptive pattern of thought that is common in people with depression and other mood disorders. It can lead to further episodes of depression, and can be very destructive in that way (Nolen-Hoeksema, 2008). This paper reviews several studies on mindfulness meditation, depression, and rumination, with a focus on certain areas and phenomena such as alpha asymmetry (Keune et al 2013) and gamma band activity (Berkovich-Ohana et al., 2012). Modalities such as fMRI and EEG are …

Bmi-1 Absence Causes Premature Brain Degeneration, Guangliang Cao, Minxia Gu, Min Zhu, Junying Gao, Ying Yin, Charles Marshall, Ming Xiao, Jiong Ding, Dengshun Miao

Physical Therapy Faculty Publications

Bmi-1, a polycomb transcriptional repressor, is implicated in cell cycle regulation and cell senescence. Its absence results in generalized astrogliosis and epilepsy during the postnatal development, but the underlying mechanisms are poorly understood. Here, we demonstrate the occurrence of oxidative stress in the brain of four-week-old Bmi-1 null mice. The mice showed various hallmarks of neurodegeneration including synaptic loss, axonal demyelination, reactive gliosis and brain mitochondrial damage. Moreover, astroglial glutamate transporters and glutamine synthetase decreased in the Bmi-1 null hippocampus, which might contribute to the sporadic epileptic-like seizures in these mice. These results indicate that Bmi-1 is required for maintaining …

Increased Mitochondrial Calcium Sensitivity And Abnormal Expression Of Innate Immunity Genes Precede Dopaminergic Defects In Pink1-Deficient Mice, Ravi S. Akundi, Zhenyu Huang, Joshua Eason, Jignesh D. Pandya, Lianteng Zhi, Wayne A. Cass, Patrick G. Sullivan, Hansruedi Büeler

Neuroscience Faculty Publications

BACKGROUND: PTEN-induced kinase 1 (PINK1) is linked to recessive Parkinsonism (EOPD). Pink1 deletion results in impaired dopamine (DA) release and decreased mitochondrial respiration in the striatum of mice. To reveal additional mechanisms of Pink1-related dopaminergic dysfunction, we studied Ca²⁺ vulnerability of purified brain mitochondria, DA levels and metabolism and whether signaling pathways implicated in Parkinson's disease (PD) display altered activity in the nigrostriatal system of Pink1⁻/⁻ mice.

METHODS AND FINDINGS: Purified brain mitochondria of ^Pink1⁻/⁻ mice showed impaired Ca²⁺ storage capacity, resulting in increased Ca²⁺ induced mitochondrial permeability transition (mPT) that was rescued by cyclosporine A. …
