Underlying Contribution Of Executive Functioning To Cognition And Academic Achievement In Individuals With Dystrophinopathy, Robert Fee 2018 The Graduate Center, City University of New York

Underlying Contribution Of Executive Functioning To Cognition And Academic Achievement In Individuals With Dystrophinopathy, Robert Fee

All Dissertations, Theses, and Capstone Projects

Dystrophinopathy is a genetic disorder that results in the lack of or abnormal expression of the protein dystrophin. It is a disorder that alters cell structure and function, impacts the developing brain and brain function, presents with multi-domain cognitive deficits, and influences both mood and behavior. Cognitive impairments appear to be more localized to specific areas of functioning rather than a global deficit; however, deficits have been identified across multiple cognitive domains including language and aspects of executive functioning. A careful examination of the cognitive phenotype and its association to mutations affecting CNS isoforms is necessary to clarify the neuropsychological ...


Girls’ Internalizing Symptoms And White Matter Tracts In Cortico-Limbic Circuitry, Ola Mohamed Ali 2018 The University of Western Ontario

Girls’ Internalizing Symptoms And White Matter Tracts In Cortico-Limbic Circuitry, Ola Mohamed Ali

Electronic Thesis and Dissertation Repository

Dysfunction in cortico-limbic circuitry is implicated in internalizing disorders, but less is known about whether structural abnormalities precede disorder, thus potentially marking risk. I therefore examined associations between white matter tract integrity in cortico-limbic circuitry at age 7, obtained using Diffusion Tensor Imaging, and concurrent and longitudinal patterns of internalizing symptoms, over a 5-year period, in 42 typically developing girls. Using Automated Fiber Quantification, diffusion properties were examined at multiple points along tract length (cf., an average diffusion measure of the entire tract). Concurrent internalizing symptoms were associated with reduced fractional anisotropy in segments of the cingulum bundle and uncinate ...


Neuronal Modulation Of Brown Adipose Activity Through Perturbation Of White Adipocyte Lipogenesis, Adilson L. Guilherme, David J. Pedersen, Felipe Henriques, Alexander H. Bedard, Elizabeth Henchey, Mark Kelly, Donald A. Morgan, Kamal Rahmouni, Michael P. Czech 2018 University of Massachusetts Medical School

Neuronal Modulation Of Brown Adipose Activity Through Perturbation Of White Adipocyte Lipogenesis, Adilson L. Guilherme, David J. Pedersen, Felipe Henriques, Alexander H. Bedard, Elizabeth Henchey, Mark Kelly, Donald A. Morgan, Kamal Rahmouni, Michael P. Czech

Open Access Articles

OBJECTIVE: Crosstalk between adipocytes and local neurons may be an important regulatory mechanism to control energy homeostasis. We previously reported that perturbation of adipocyte de novo lipogenesis (DNL) by deletion of fatty acid synthase (FASN) expands sympathetic neurons within white adipose tissue (WAT) and stimulates the appearance of "beige" adipocytes. Here we tested whether WAT DNL activity can also influence neuronal regulation and thermogenesis in brown adipose tissue (BAT).

METHODS AND RESULTS: Induced deletion of FASN in all adipocytes in mature mice (iAdFASNKO) enhanced sympathetic innervation and neuronal activity as well as UCP1 expression in both WAT and BAT. This ...


Analysis Of Novel Caudal Hindbrain Genes Reveals Different Regulatory Logic For Gene Expression In Rhombomere 4 Versus 5/6 In Embryonic Zebrafish, Priyanjali Ghosh, Jennifer M. Maurer, Charles G. Sagerstrom 2018 University of Massachusetts Medical School

Analysis Of Novel Caudal Hindbrain Genes Reveals Different Regulatory Logic For Gene Expression In Rhombomere 4 Versus 5/6 In Embryonic Zebrafish, Priyanjali Ghosh, Jennifer M. Maurer, Charles G. Sagerstrom

Open Access Articles

BACKGROUND: Previous work aimed at understanding the gene regulatory networks (GRNs) governing caudal hindbrain formation identified morphogens such as Retinoic Acid (RA) and Fibroblast growth factors (FGFs), as well as transcription factors like hoxb1b, hoxb1a, hnf1ba, and valentino as being required for rhombomere (r) r4-r6 formation in zebrafish. Considering that the caudal hindbrain is relatively complex - for instance, unique sets of neurons are formed in each rhombomere segment - it is likely that additional essential genes remain to be identified and integrated into the caudal hindbrain GRN.

METHODS: By taking advantage of gene expression data available in the Zebrafish Information Network ...

Grant, Anais Martinez, Gully Apc Burns, Brendan S. Thatcher, Vishwanath T. Anekonda, Benjamin W. Thompson, Zachary S. Roberts, Daniel H. Moralejo, James E. Blevins

Arshad M. Khan, Ph.D.

This article, which includes novel unpublished data along with commentary and analysis,
focuses on approaches to link transcriptomic, proteomic, and peptidomic datasets mined from
brain tissue to the original locations within the brain that they are derived from using digital atlas
mapping techniques. We use, as an example, the transcriptomic, proteomic and peptidomic
analyses conducted in the mammalian hypothalamus. Following a brief historical overview, we
highlight studies that have mined biochemical and molecular information from the hypothalamus
and then lay out a strategy for how these data can be linked spatially to the mapped locations in a
canonical brain atlas ...


Ephrinb3 Modulates Hippocampal Neurogenesis And The Reelin Signaling Pathway In A Pilocarpineinduced Model Of Epilepsy, Tian-Tian Liu, Yi Li, Yi Shu, Bo Xiao, Li Feng 2018 Central South University

Ephrinb3 Modulates Hippocampal Neurogenesis And The Reelin Signaling Pathway In A Pilocarpineinduced Model Of Epilepsy, Tian-Tian Liu, Yi Li, Yi Shu, Bo Xiao, Li Feng

Open Access Articles

EphrinB3 is important in the regulation of cell proliferation, differentiation and migration via cellcell contact, and can activate the reelin pathway during brain development. However, the effect of ephrinB3 on hippocampal neurogenesis and the reelin pathway in epilepsy remains to be fully elucidated. In the present study, the expression of ephrinB3 in pilocarpineinduced status epilepticus (SE) rats was investigated. SYBR Greenbased reverse transcriptionquantitative polymerase chain reaction analysis, immunohistochemical labeling and western blot analysis were used to detect the gene and protein expression levels of ephrinB3 and reelin pathway proteins. Immunofluorescence staining of doublecortin (DCX) was utilized to analyze hippocampal neurogenesis ...


Modeling Emmetropization In An Incessantly Moving Eye, Michele Rucci, Jonathan D. Victor 2018 University of Rochester

Modeling Emmetropization In An Incessantly Moving Eye, Michele Rucci, Jonathan D. Victor

MODVIS Workshop

Many questions remain unanswered regarding the specific cues and mechanisms for emmetropization, the process by which, during development, the eye adjusts itself so that distant objects are in focus. Research has so far primarily focused on the spatial cues present in the image on the retina, such as the degree of blur. However, eye movements incessantly transform a mostly static scene into temporal modulations, so that the input to the retina is not an image, but a spatiotemporal flow of luminance. Models of retinal input signals indicate that this space-time reformatting caused by eye movements yields additional cues to the ...

Childhood Poverty And Its Effects On The Brain: Physiological And Functional Implications, Lauren Scandrett 2018 University of Wyoming

Childhood Poverty And Its Effects On The Brain: Physiological And Functional Implications, Lauren Scandrett

Honors Theses AY 17/18

One out of every five American children lives below the federal poverty line. Considering that poverty is deemed one of the most influential risk factors for poor developmental outcomes, it is critical to understand what effect poverty has on the developing brain and how those brain changes affect a child’s life. Poverty is chiefly defined by having a low socioeconomic status (SES), but a low SES is often accompanied by other influencers, such as nutrition and mental stimulation, termed poverty co-factors. Other poverty co-factors include, but are not limited to, maternal stress and malnutrition, environmental toxins, parental nurturance, and ...


Moderate Prenatal Alcohol Exposure Impairs Performance In An Object-Place-Paired-Associate Task, Lilliana May Sanchez 2018 University of New Mexico - Main Campus

Moderate Prenatal Alcohol Exposure Impairs Performance In An Object-Place-Paired-Associate Task, Lilliana May Sanchez

Psychology ETDs

Memory impairments, including spatial and object processing, are often observed in individuals with Fetal Alcohol Spectrum Disorder. Much attention has been directed towards the hippocampus, which displays significant alterations after moderate prenatal alcohol exposure (PAE). In the present study, we tested a moderate PAE rat model in an object-place-paired-associate (OPPA) task, previously shown to require hippocampal processing. The OPPA task was composed of training rats to discriminate between an identical pair of objects presented in 180° opposite arms of a radial arm maze. Animals were given a total of 10 trials per day over 14 consecutive days of training and ...


The Role Of The Chorda Tympani Nerve In The Structural Development Of Brainstem Neurons, Louis Martin 2018 University of Nebraska at Omaha

The Role Of The Chorda Tympani Nerve In The Structural Development Of Brainstem Neurons, Louis Martin

Student Research and Creative Activity Fair

The brain changes substantially throughout development. In the taste system, brainstem neurons undergo dramatic structural alterations after birth. Most notably, these cells’ dendrites, branch-like projections that that receive sensory input, grow 3-4 times longer by adulthood. It is not clear whether incoming signals about taste are necessary for these structural changes to occur. We have consistently found that when the chorda tympani taste nerve (CT) is cut at an early age in rats, it does not regenerate. With this manipulation, we can permanently limit the amount of taste information that reaches the brain. To determine the role of taste input ...


A Cre-Inducible Dux4 Transgenic Mouse Model For Investigating Facioscapulohumeral Muscular Dystrophy, Takako I. Jones, Peter L. Jones 2018 University of Massachusetts Medical School

A Cre-Inducible Dux4 Transgenic Mouse Model For Investigating Facioscapulohumeral Muscular Dystrophy, Takako I. Jones, Peter L. Jones

Open Access Articles

The Double homeobox 4 (DUX4) gene is an important regulator of early human development and its aberrant expression is causal for facioscapulohumeral muscular dystrophy (FSHD). The DUX4-full length (DUX4-fl) mRNA splice isoform encodes a transcriptional activator; however, DUX4 and its unique DNA binding preferences are specific to old-world primates. Regardless, the somatic cytotoxicity caused by DUX4 expression is conserved when expressed in cells and animals ranging from fly to mouse. Thus, viable animal models based on DUX4-fl expression have been difficult to generate due in large part to overt developmental toxicity of low DUX4-fl expression from leaky transgenes. We have ...


Social Influences On Songbird Behavior: From Song Learning To Motion Coordination, Iva Ljubičić 2018 The Graduate Center, City University of New York

Social Influences On Songbird Behavior: From Song Learning To Motion Coordination, Iva Ljubičić

All Dissertations, Theses, and Capstone Projects

Social animals learn during development how to integrate successfully into their group. How do social interactions combine to maintain group cohesion? We first review how social environments can influence the development of vocal learners, such as songbirds and humans (Chapter 1). To bypass the complexity of natural social interactions and gain experimental control, we developed Virtual Social Environments, surrounding the bird with videos of manipulated playbacks. This way we were able to design sensory and social scenarios and test how social zebra finches adjust their behavior (Chapters 2 & 3). A serious challenge is that the color output of a video ...


Biological Signatures Of Emotion Regulation In Children, Sarah Myruski 2018 The Graduate Center, City University of New York

Biological Signatures Of Emotion Regulation In Children, Sarah Myruski

All Dissertations, Theses, and Capstone Projects

Emotion regulation (ER) is a key predictor of positive adjustment throughout the lifespan. Despite decades of research on discrete ER strategy use, ER may be more appropriately measured in terms of the breadth of emotional range, or the degree to which one can flexibly modulate emotional responses. Yet little is known about ER flexibility in childhood. Also, given the crucial role of caregiver support in children’s emotional lives, ER may be most accurately measured in developmentally appropriate and ecologically valid social contexts. Further, few developmental studies have capitalized on the growing evidence base surrounding biological signatures of ER. This ...


The Rhetoric Of Science Education And Technology, Iwasan D. Kejawa 2018 University of Nebraska-Lincoln

The Rhetoric Of Science Education And Technology, Iwasan D. Kejawa

CSE Journal Articles

Nearly thousands of science experiments are performed both on humans and animals every year in the United States (Gregory, 1999). Does Science enormously play a role in the well-beings of individual in the society? Research has found that science education is through motivation and satisfying the needs of humans. The scientific world is part of an elongated human development. This can be substantiated with the use and evolution of TECHNOLOGY and SCIENCE (Minton, 2004). Education of the entities that comprise the need to achieve the goal of TECHNOLOGY and SCIENCE which are important issues of today. Research has shown that ...


Targeting Of Central Nucleus Projections To Extramodular Zones Of The Lateral Cortex Of The Inferior Colliculus In Developing Mouse, Isabel D. Lamb-Echegaray 2018 James Madison University

Targeting Of Central Nucleus Projections To Extramodular Zones Of The Lateral Cortex Of The Inferior Colliculus In Developing Mouse, Isabel D. Lamb-Echegaray

Senior Honors Projects, 2010-current

The multimodal lateral cortex of the inferior colliculus (LCIC) exhibits a modular-extramodular micro-organization that is evident early in development. In addition to a set of neurochemical markers that reliably highlight its modular-extramodular organization, mature projection patterns in a variety of adult species suggest that major LCIC afferents also recognize and adhere to such a framework. This patch-matrix-like arrangement appears to segregate into distinct afferent streams, with somatosensory inputs targeting LCIC modules and auditory inputs targeting surrounding extramodular zones. Currently lacking is a detailed understanding of the development and shaping of multimodal LCIC afferents with respect to its modular-extramodular framework. The ...


Creativity, Laterality And Critical State Balance In Learning, Jenny Rock, Asher Flatt 2017 University of Otago

Creativity, Laterality And Critical State Balance In Learning, Jenny Rock, Asher Flatt

The STEAM Journal

Understanding the intersecting cognitive pathways that are integral to ways of thinking, creating and functioning in both art and science is an important grounding for a STEAM educational approach. We combine three divergent concepts, including creativity, hemisphere laterality, and critical state theory, to argue for a more balanced approach to learning as part of a modern meaning-centered education in STEAM. Reviewing the concept of hemisphere laterality, or how the two hemispheres of our brain have different (though not disconnected) ways of processing sensory information, we note how these two means of interpreting the world have become unbalanced in traditional modes ...


Type 2 Neural Progenitor Cell Activation Drives Reactive Neurogenesis After Binge-Like Alcohol Exposure In Adolescent Male Rats, Chelsea Rhea Geil Nickell, Hui Peng, Dayna M. Hayes, Kevin Y. Chen, Justin A. McClain, Kimberly Nixon 2017 University of Kentucky

Type 2 Neural Progenitor Cell Activation Drives Reactive Neurogenesis After Binge-Like Alcohol Exposure In Adolescent Male Rats, Chelsea Rhea Geil Nickell, Hui Peng, Dayna M. Hayes, Kevin Y. Chen, Justin A. Mcclain, Kimberly Nixon

Pharmaceutical Sciences Faculty Publications

Excessive alcohol consumption during adolescence remains a significant health concern as alcohol drinking during adolescence increases the likelihood of an alcohol use disorder in adulthood by fourfold. Binge drinking in adolescence is a particular problem as binge-pattern consumption is the biggest predictor of neurodegeneration from alcohol and adolescents are particularly susceptible to the damaging effects of alcohol. The adolescent hippocampus, in particular, is highly susceptible to alcohol-induced structural and functional effects, including volume and neuron loss. However, hippocampal structure and function may recover with abstinence and, like in adults, a reactive burst in hippocampal neurogenesis in abstinence may contribute to ...


Preschoolers And Pandas Making Friends: A Journey About Healing From Brain Injury, Barbara Anne Doucette 2017 State University of New York College at Buffalo - Buffalo State College

Preschoolers And Pandas Making Friends: A Journey About Healing From Brain Injury, Barbara Anne Doucette

Museum Studies Projects

Preschoolers that have obtained Non-Accidental Injury (NAI) from familial child abuse are in need of having a unique place for neurorehabilitation in correlation with traditional therapies. My thesis project suggests adding an exhibit annex to an existing giant panda exhibit that will give preschoolers an opportunity to help develop new neuropathways when exposed to mediation and creative activities. Meditation and creative activities are being examined by neuroscientists as an aid in neuroplasticity after brain injury. This thesis reviews the neurotypical preschooler’s milestones and the playful means by which they are achieved. Conjoining the contemporary museums’ and zoological gardens’ outreach ...

Signaling cascades, such as the extracellular signal-regulated kinase (ERK) pathway, play vital roles in early vertebrate development. Signals through these pathways are initiated by a growth factor or hormone, are transduced through a kinase cascade, and result in the expression of specific downstream genes that promote cellular proliferation, growth, or differentiation.Tight regulation of these signals is provided by positive or negative modulators at varying levels in the pathway, and is required for proper development and function. Two members of the dual-specificity phosphatase (Dusp) family, dusp6 and dusp2, are believed to be negative regulators of the ERK pathway and are ...
