Resting State Electrophysiological Profiles And Their Relationship With Cognitive Performance In Cognitively Unimpaired Older Adults: A Systematic Review, Brenda Chino, David López-Sanz, Sandra Doval, Lucía Torres-Simón, Jaisalmer De Frutos Lucas, Lydia Giménez-Llort, Jonathan Zegarra-Valdivia, Fernando Maestú

Research outputs 2022 to 2026

Background: Aging is a complex and natural process. The physiological decline related to aging is accompanied by a slowdown in cognitive processes, which begins shortly after individuals reach maturity. These changes have been sometimes interpreted as a compensatory sign and others as a fingerprint of deterioration. Objective: In this context, our aim is to uncover the mechanisms that underlie and support normal cognitive functioning in the brain during the later stages of life. Methods: With this purpose, a systematic literature search was conducted using PubMed, Scopus, and Web of Science databases, which identified 781 potential articles. After applying inclusion and …

Bayesian Varying-Effects Vector Autoregressive Models For Inference Of Brain Connectivity Networks And Covariate Effects In Pediatric Traumatic Brain Injury, Yangfan Ren, Nathan Osborne, Christine B Peterson, Dana M Demaster, Linda Ewing-Cobbs, Marina Vannucci

Faculty, Staff and Student Publications

In this article, we develop an analytical approach for estimating brain connectivity networks that accounts for subject heterogeneity. More specifically, we consider a novel extension of a multi-subject Bayesian vector autoregressive model that estimates group-specific directed brain connectivity networks and accounts for the effects of covariates on the network edges. We adopt a flexible approach, allowing for (possibly) nonlinear effects of the covariates on edge strength via a novel Bayesian nonparametric prior that employs a weighted mixture of Gaussian processes. For posterior inference, we achieve computational scalability by implementing a variational Bayes scheme. Our approach enables simultaneous estimation of group-specific …

Pure Epidural Extraosseous Cavernous Hemangioma With Thoracic Myelopathy: Case Report And Review Of Literature, Jordan Guntin, Ashley Ricciardelli, Alex Flores, Jeffrey Chen, Jeffrey Treiber, Alfonso Fuentes

Faculty, Staff and Students Publications

Introduction: Pure epidural spinal cavernous hemangiomas are rare, benign vascular tumors that account for approximately 4% of all spinal epidural tumors. Due to their dumbbell shape and propensity for foraminal invasion, they are often misdiagnosed and inadequately treated. We present a case of a 58-year-old male with extra-osseous cavernous hemangioma to better aid in diagnosis and management of these lesions.

Case presentation: A 58-year-old male presented with chronic lower back pain, progressive lower extremity weakness, T10 sensory level, absent lower extremity proprioception, hyperreflexia, and an episode of bowel incontinence. Imaging demonstrated T7-T10 homogenous dorsal epidural mass causing cord signal change. …

Tractography-Based Modeling Explains Treatment Outcomes In Patients Undergoing Deep Brain Stimulation For Obsessive-Compulsive Disorder, Ron Gadot, Ningfei Li, Ben Shofty, Michelle Avendano-Ortega, Sarah Mckay, Kelly R Bijanki, Meghan E Robinson, Garrett Banks, Nicole Provenza, Eric A Storch, Wayne K Goodman, Andreas Horn, Sameer A Sheth

BACKGROUND: Deep brain stimulation (DBS) is an established and expanding therapy for treatment-refractory obsessive-compulsive disorder. Previous work has suggested that a white matter circuit providing hyperdirect input from the dorsal cingulate and ventrolateral prefrontal regions to the subthalamic nucleus could be an effective neuromodulatory target.

METHODS: We tested this concept by attempting to retrospectively explain through predictive modeling the ranks of clinical improvement as measured by the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) in 10 patients with obsessive-compulsive disorder who underwent DBS to the ventral anterior limb of internal capsule with subsequent programming uninformed by the putative target tract.

RESULTS: Rank …

Beta Activity In Human Anterior Cingulate Cortex Mediates Reward Biases, Jiayang Xiao, Joshua A Adkinson, John Myers, Anusha B Allawala, Raissa K Mathura, Victoria Pirtle, Ricardo Najera, Nicole R Provenza, Eleonora Bartoli, Andrew J Watrous, Denise Oswalt, Ron Gadot, Adrish Anand, Ben Shofty, Sanjay J Mathew, Wayne K Goodman, Nader Pouratian, Xaq Pitkow, Kelly R Bijanki, Benjamin Hayden, Sameer A Sheth

The rewards that we get from our choices and actions can have a major influence on our future behavior. Understanding how reward biasing of behavior is implemented in the brain is important for many reasons, including the fact that diminution in reward biasing is a hallmark of clinical depression. We hypothesized that reward biasing is mediated by the anterior cingulate cortex (ACC), a cortical hub region associated with the integration of reward and executive control and with the etiology of depression. To test this hypothesis, we recorded neural activity during a biased judgment task in patients undergoing intracranial monitoring for …

Gene Expression Analysis Reveals Dysregulation In Traumatic Brain Injury Leading To Tauopathy, Kristina M. Tosi

USF Tampa Graduate Theses and Dissertations

Traumatic Brain Injury (TBI) causes a cascade of detrimental events within neurons, contributing to a host of neurological diseases relating to dementia. In this study we have performed a meta-analysis comparing differentially expressed genes (DEG) in specific cell types such as neurons and microglia revealing inflammation as a common driver of neurological deficiencies post TBI. Inflammation and hypoxia are well characterized features of TBI; however, the molecular mechanisms causing tau hyperphosphorylation by tauopathy associated genes (TAG) post-TBI are currently poorly understood. Furthermore, there are limited in-vitro neuroinflammatory models that mimic primary and secondary TBI. We hypothesize that inducing hypoxia and …

27-Hydroxycholesterol Acts On Estrogen Receptor Α Expressed By Pomc Neurons In The Arcuate Nucleus To Modulate Feeding Behavior, Hui Ye, Xiaohua Yang, Bing Feng, Pei Luo, Valeria C Torres Irizarry, Leslie Carrillo-Sáenz, Meng Yu, Yongjie Yang, Benjamin P Eappen, Marcos David Munoz, Nirali Patel, Sarah Schaul, Lucas Ibrahimi, Penghua Lai, Xinyue Qi, Yuliang Zhou, Maya Kota, Devin Dixit, Madeline Mun, Chong Wee Liew, Yuwei Jiang, Chunmei Wang, Yanlin He, Pingwen Xu

Oxysterols are metabolites of cholesterol that regulate cholesterol homeostasis. Among these, the most abundant oxysterol is 27-hydroxycholesterol (27HC), which can cross the blood-brain barrier. Because 27HC functions as an endogenous selective estrogen receptor modulator, we hypothesize that 27HC binds to the estrogen receptor α (ERα) in the brain to regulate energy balance. Supporting this view, we found that delivering 27HC to the brain reduced food intake and activated proopiomelanocortin (POMC) neurons in the arcuate nucleus of the hypothalamus (POMCARH) in an ERα-dependent manner. In addition, we observed that inhibiting brain ERα, deleting ERα in POMC neurons, or chemogenetic inhibition of …

Ragopathies And The Rising Influence Of Raggtpases On Human Diseases, Irene Sambri, Marco Ferniani, Andrea Ballabio

Duncan NRI Faculty and Staff Publications

RagGTPases (Rags) play an essential role in the regulation of cell metabolism by controlling the activities of both mechanistic target of rapamycin complex 1 (mTORC1) and Transcription factor EB (TFEB). Several diseases, herein named ragopathies, are associated to Rags dysfunction. These diseases may be caused by mutations either in genes encoding the Rags, or in their upstream regulators. The resulting phenotypes may encompass a variety of clinical features such as cataract, kidney tubulopathy, dilated cardiomyopathy and several types of cancer. In this review, we focus on the key clinical, molecular and physio-pathological features of ragopathies, aiming to shed light on …

Persistent Interruption In Parvalbuminpositive Inhibitory Interneurons: Biophysical And Mathematical Mechanisms, Carol M. Upchurch, Christopher J. Knowlton, Simon Chamberland, Carmen C. Canavier

School of Graduate Studies Faculty Publications

Persistent activity in excitatory pyramidal cells (PYRs) is a putative mechanism for maintaining memory traces during working memory. We have recently demonstrated persistent interruption of firing in fastspiking parvalbumin-expressing interneurons (PV-INs), a phenomenon that could serve as a substrate for persistent activity in PYRs through disinhibition lasting hundreds of milliseconds. Here, we find that hippocampal CA1 PV-INs exhibit type 2 excitability, like striatal and neocortical PV-INs. Modeling and mathematical analysis showed that the slowly inactivating potassium current KV1 contributes to type 2 excitability, enables the multiple firing regimes observed experimentally in PV-INs, and provides a mechanism for robust persistent interruption …

Dissociation Of Reading And Naming In Ventral Occipitotemporal Cortex, Oscar Woolnough, Nitin Tandon

Faculty, Staff and Student Publications

Lesions in the language-dominant ventral occipitotemporal cortex (vOTC) can result in selective impairment of either reading or naming, resulting in alexia or anomia. Yet, functional imaging studies that show differential activation for naming and reading do not reveal activity exclusively tuned to one of these inputs. To resolve this dissonance in the functional architecture of the vOTC, we used focused stimulation to the vOTC in 49 adult patients during reading and naming, and generated a population-level, probabilistic map to evaluate if reading and naming are clearly dissociable within individuals. Language mapping (50 Hz, 2829 stimulations) was performed during passage reading …

Tiam1-Mediated Maladaptive Plasticity Underlying Morphine Tolerance And Hyperalgesia, Changqun Yao, Xing Fang, Qin Ru, Wei Li, Jun Li, Zeinab Mehsein, Kimberley F Tolias, Lingyong Li

Faculty, Staff and Students Publications

Opioid pain medications, such as morphine, remain the mainstay for treating severe and chronic pain. Prolonged morphine use, however, triggers analgesic tolerance and hyperalgesia (OIH), which can last for a long period after morphine withdrawal. How morphine induces these detrimental side effects remains unclear. Here, we show that morphine tolerance and OIH are mediated by Tiam1-coordinated synaptic structural and functional plasticity in the spinal nociceptive network. Tiam1 is a Rac1 GTPase guanine nucleotide exchange factor that promotes excitatory synaptogenesis by modulating actin cytoskeletal dynamics. We found that prolonged morphine treatment activated Tiam1 in the spinal dorsal horn and Tiam1 ablation …

What’S The N? On Sample Size Vs. Subject Number For Brain-Behavior Neurophysiology And Neuromodulation, Wael F Asaad, Sameer A Sheth

Duncan NRI Faculty and Staff Publications

Neurophysiology and neuromodulation strive to understand the neural basis of behavior through a one-to-one correspondence between a particular brain and its behavioral output. Within this framework, studies with few subjects but sufficient sample sizes can be both rigorous and impactful.

Towards An Interdisciplinary “Science Of The Mind”: A Call For Enhanced Collaboration Between Philosophy And Neuroscience, Alessandra Buccella, Uri Maoz, Liad Mudrik

Psychology Faculty Articles and Research

In recent decades, the neuroscientific community has moved from describing the neural underpinnings of mental phenomena—as characterized by experimental psychology and philosophy of mind—to attempting to redefine those mental phenomena based on neural findings. Nowadays, many are intrigued by the idea that neuroscience might provide the “missing piece” that would allow philosophers (and, to an extent, psychologists, too) to make important advances, generating new means that these disciplines lack to close knowledge gaps and answer questions like “What is Free Will?” and “Do humans have it?.” In this paper, we argue that instead of striving for neuroscience to replace philosophy …

In Search Of The Locus Coeruleus: Guidelines For Identifying Anatomical Boundaries And Electrophysiological Properties Of The Blue Spot In Mice, Fish, Finches, And Beyond, Amelien Vreven, Gary Aston-Jones, Anthony E Pickering, Gina R Poe, Barry Waterhouse, Nelson K Totah

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Our understanding of human brain function can be greatly aided by studying analogous brain structures in other organisms. One brain structure with neurochemical and anatomical homology throughout vertebrate species is the locus coeruleus (LC), a small collection of norepinephrine (NE)-containing neurons in the brainstem that project throughout the central nervous system. The LC is involved in nearly every aspect of brain function, including arousal and learning, which has been extensively examined in rats and nonhuman primates using single-unit recordings. Recent work has expanded into putative LC single-unit electrophysiological recordings in a nonmodel species, the zebra finch. Given the importance of …

Objective: Congenital anomalies of the atlanto-occipital articulation may be present in patients with Chiari malformation type I (CM-I). However, it is unclear how these anomalies affect the biomechanical stability of the craniovertebral junction (CVJ) and whether they are associated with an increased incidence of occipitocervical fusion (OCF) following posterior fossa decompression (PFD). The objective of this study was to determine the prevalence of condylar hypoplasia and atlas anomalies in children with CM-I and syringomyelia. The authors also investigated the predictive contribution of these anomalies to the occurrence of OCF following PFD (PFD+OCF).

Methods: The authors analyzed the prevalence of condylar …

BACKGROUND: A bioactive myelin basic protein (MBP) fragment, comprising MBP

METHODS: In male and female normal and post-CCI rat sciatic nerves, we assessed: (i) cholesterol precursor and metabolite levels by lipidomics; (ii) MBP

RESULTS: CCI regulated LXRα ligand and receptor levels in nerves of both sexes, with cholesterol precursors, desmosterol and 7-DHC, and oxysterol elevated in females relative to males. MBP

CONCLUSION: The injury-released bioactive MBP fragments induce pronociceptive changes by selective inactivation of nuclear transcription factors, including LXRα. By Ncoa1 sequestration, bioactive MBP fragments render LXRα function to counteract pronociceptive activity of estrogen/ESR1 in sensory neurons. This effect of …

Lafora disease (LD) is a syndrome of progressive myoclonic epilepsy and cumulative neurocognitive deterioration caused by recessively inherited genetic lesions of EPM2A (laforin) or NHLRC1 (malin). Neuropsychiatric symptomatology in LD is thought to be directly downstream of neuronal and astrocytic polyglucosan aggregates, termed Lafora bodies (LBs), which faithfully accumulate in an age-dependent manner in all mouse models of LD. In this study, we applied home-cage monitoring to examine the extent of neurobehavioral deterioration in a model of malin-deficient LD as a means to identify robust preclinical endpoints that may guide the selection of novel genetic treatments. At 6 weeks, ∼6-7 …

Endovascular Management Of A Ruptured Aneurysm On A Posterior Inferior Cerebellar Artery With Extradural C2-Origin: Case Report And Literature Review, Rasmus Holmboe Dahl, Gary Lloyd Horn, Zeyad Metwalli, Shankar Prakash Gopinath, Goetz Benndorf

Faculty, Staff and Students Publications

Extracranial vascular pathology uncommonly causes intracranial subarachnoid hemorrhage (SAH). Among possible lesions are aneurysms at the craniocervical junction arising from a posterior inferior cerebellar artery (PICA) with an extradural origin. We describe a case of a 55-year-old female presenting with a sudden and severe headache. A computed tomography scan revealed a SAH within the fourth ventricle and cervical spinal canal, and a ruptured saccular aneurysm on a PICA with extradural C2-origin. Despite difficult access anatomy, endovascular treatment was feasible and resulted in subtotal initial occlusion and preservation of distal PICA flow. Upon 3-month follow-up, the aneurysm was completely occluded with …

Subpial Resection Of Epileptogenic Tubers: Operative Nuances And Lessons Learned, Nisha Giridharan, Collin W English, Marcus Wong, Howard L Weiner

Faculty, Staff and Students Publications

Tuberous sclerosis complex (TSC) is an autosomal dominant neurocutaneous disorder. Tubers of the central nervous system are a hallmark of the disorder and often cause epilepsy. Many TSC patients fail to achieve seizure control with medication alone. Several case series have demonstrated high seizure freedom rates after resective surgery. However, the technique for the resection of epileptogenic tubers has largely been unreported. Here the authors present 2 cases to illustrate their multistage approach for localizing and resecting the seizure onset zone in patients with TSC. At their institution, they have excellent seizure outcomes and a low complication rate with this …

Resting State Electroencephalographic Brain Activity In Neonates Can Predict Age And Is Indicative Of Neurodevelopmental Outcome, Amir Ansari, Kirubin Pillay, Emad Arasteh, Anneleen Dereymaeker, Gabriela Schmidt Mellado, Katrien Jansen, Anderson M. Winkler, Gunnar Naulaers, Aomesh Bhatt, Sabine Van Huffel

School of Medicine Publications

Objective: Electroencephalography (EEG) can be used to estimate neonates' biological brain age. Discrepancies between postmenstrual age and brain age, termed the brain age gap, can potentially quantify maturational deviation. Existing brain age EEG models are not well suited to clinical cot-side use for estimating neonates' brain age gap due to their dependency on relatively large data and pre-processing requirements.

Methods: We trained a deep learning model on resting state EEG data from preterm neonates with normal neurodevelopmental Bayley Scale of Infant and Toddler Development (BSID) outcomes, using substantially reduced data requirements. We subsequently tested this model in two independent datasets …

Research outputs 2022 to 2026

Purpose of Review: This narrative review evaluates the role of diet in the relationship between depression and Alzheimer's disease (AD). Recent Findings: AD and depression are often comorbid, and depression appears to independently increase the future risk of AD. Evidence suggests diet influences the risk of both conditions directly and indirectly. Diet impacts neurochemical and biological processes that may affect the development and progression of depression and cognitive dysfunction. The dietary components offering the greatest protection against depression and AD are yet to be determined. Current evidence highlights the importance of polyphenolic compounds, folate, B vitamins, and polyunsaturated fatty acids, …

Deficits in memory performance have been linked to a wide range of neurological and neuropsychiatric conditions. While many studies have assessed the memory impacts of individual conditions, this study considers a broader perspective by evaluating how memory recall is differentially associated with nine common neuropsychiatric conditions using data drawn from 55 international studies, aggregating 15,883 unique participants aged 15–90. The effects of dementia, mild cognitive impairment, Parkinson’s disease, traumatic brain injury, stroke, depression, attention-deficit/hyperactivity disorder (ADHD), schizophrenia, and bipolar disorder on immediate, short-, and long-delay verbal learning and memory (VLM) scores were estimated relative to matched healthy individuals.

Assessing The Effects Of Repetitive Mild Traumatic Brain Injury On Risk/Reward Decision Making And Catecholamine Associated Proteins, Christopher Knapp

Theses and Dissertations

Mild traumatic brain injury (mTBI) disrupts cognitive processes that influence risk taking behavior; however, the effects of repetitive mild injury (rmTBI) or whether these outcomes are sex specific are unknown. Risk/reward decision making is mediated by the prefrontal cortex (PFC), which is densely innervated by catecholaminergic fibers. Aberrant PFC catecholamine activity has been documented following TBI and may underlie TBI-induced risky behavior. Here, we exposed rats to sham (no injury), single, or three closed-head controlled cortical impact (CH-CCI) injuries to characterize the effects of rmTBI on 1) risk/reward decision making behavior using a probabilistic discounting task (PDT) and 2) levels …

Physiological And Circadian Outcomes Of Fkbp5 Imbalance: Insights From Two Models, Niat Tsegai Gebru

USF Tampa Graduate Theses and Dissertations

Circadian rhythms are crucial in regulating various physiological processes, including mood regulation, and disruptions in these rhythms have been linked to several neuropsychiatric disorders, such as depression, bipolar disorder, and schizophrenia. FKBP51, a protein involved in stress responses and glucocorticoid receptor function has emerged as a potential regulator of the circadian clock. FKBP51’s interaction with glucocorticoid receptors impacts the transcriptional regulation of circadian-related genes. In recent years, FKBP51 has been associated with genetic and epigenetic alterations in neuropsychiatric disorders, highlighting its potential as a target for intervention. The heterogeneity associated with neuropsychiatric disorders arises from a combination of genetic, environmental, …

Roles Of Mitochondrial Chchd2 And Gpcr-Associated Β-Arrestin2 In The Pathogenesis Of Lewy Body Disorders, Teresa R. Kee

USF Tampa Graduate Theses and Dissertations

Coiled-coil-helix-coiled-coil-helix domain containing 2 (CHCHD2) is a mitochondrial protein that plays important roles in cristae structure, oxidative phosphorylation, and apoptosis. Multiple mutations in CHCHD2 have been associated with Lewy body disorders (LBDs), such as Parkinson’s disease (PD) and dementia with Lewy bodies (DLB), with the CHCHD2T61I mutation being the most widely studied. We generated the first transgenic mouse models expressing human CHCHD2WT and the PD-linked CHCHD2T61I mutation driven by the mPrP promoter. CHCHD2T61I Tg, but not CHCHD2WT Tg mice exhibit perinuclear mitochondrial aggregates, neuroinflammation, and have impaired long-term synaptic plasticity associated with synaptic dysfunction. Dopaminergic neurodegeneration, a hallmark of PD, …
