In sports concussion research, obtaining quality data from a sufficient number of participants to reach statistical power has been a particular problem. In addition, the necessary requirements of accessibility, informed consent, and confidentiality must be met. There is need to develop more efficient and controlled methods for collecting data to answer research questions in this realm, but the ability to collect and store these data in an efficient manner at the local level is limited. By virtue of their training, neuropsychologists can play a key role in improving data collection quality. The purpose of this paper is to describe a ...
An Initial Analysis Of A Long-Term Ketogenic Diet’S Impact On Motor Behavior, Brain Purine Systems, And Nigral Dopamine Neurons In A New Genetic Rodent Model Of Parkinson’S Disease, 2016 Trinity College
An Initial Analysis Of A Long-Term Ketogenic Diet’S Impact On Motor Behavior, Brain Purine Systems, And Nigral Dopamine Neurons In A New Genetic Rodent Model Of Parkinson’S Disease, Jacob Rubin, William H. Church
Senior Theses and Projects
A growing body of research suggests that dopaminergic cell death seen in Parkinson’s disease is caused by mitochondrial dysfunction. Oxidative stress, with subsequent generation of reactive oxygen species, is the hallmark biochemical product of mitochondrial dysfunction. The ketogenic diet has been found to enhance mitochondrial energy production, protect against reactive oxygen species-generated cell death, and increase adenosine, a purine that modulates dopamine activity. The current study evaluates the effects of a long-term (5-month) ketogenic diet on behavioral, neurochemical, and neuroanatomical measures in PINK1-KO rats, a new animal model of Parkinson’s disease. Both wild-type and PINK1-KO animals fed a ...
Effect Of Zymosan-Induced Peritonitis On The Expression Of Substance P In Primary Sensory Neurons And Spinal Nerve Processes, 2016 East Tennessee State Universtiy
Effect Of Zymosan-Induced Peritonitis On The Expression Of Substance P In Primary Sensory Neurons And Spinal Nerve Processes, Michael G. Armstrong
Undergraduate Honors Theses
Macrophages and other cells of the innate immune system recognize foreign particles that could be potentially dangerous and respond by initiating an inflammatory response. The biologically active chemical mediators of this response called pro-inflammatory cytokines are produced in various myeloid derived immune cells and can affect other cells of the body. Interleukin-1β, a pro-inflammatory cytokine, has been shown to have direct effects on dorsal root ganglion (DRG) cell bodies including the upregulation and direct release of a nociceptive neurotransmitter called substance P (SP). Using a zymosan-induced model of systemic inflammation, we hypothesized that murine DRG neurons and the nerve processes ...

An In Vivo Study Of The Effects Of Perinatal Caffeine Exposure On Synaptic Efficacy In The Hippocampus Of Freely Moving Adult Rats, 2016 Trinity College, Hartford Connecticut
An In Vivo Study Of The Effects Of Perinatal Caffeine Exposure On Synaptic Efficacy In The Hippocampus Of Freely Moving Adult Rats, Jee Eun Park
Senior Theses and Projects
The synapse from the perforant path to the dentate gyrus has been widely used successfully to demonstrate long-term potentiation, a cellular model underlying learning and memory. Caffeine is one of the most widely consumed psychoactive stimulants in the world. Caffeine consumption increases in alertness, improvements in motor skills, and neurological functions, and these effects have promoted its use throughout history. Although the many short term cognitive benefits of caffeine intake are well understood, the long term effects of caffeine exposure have been widely disputed. Despite this, it is estimated that over 80% of women continue to consume caffeine throughout pregnancy ...
The Effects Of The Ketogenic Diet (Kd) On Inflammatory Pain, 2016 Trinity College, Hartford Connecticut
The Effects Of The Ketogenic Diet (Kd) On Inflammatory Pain, Livia S. Wyss
Senior Theses and Projects
BACKGROUND: Pain is the most common ailment around the world, according to the American Academy of Pain Medicine; 100 million Americans suffer with chronic pain, which is more than any other main disorder and is described by more than 60% as impacted their overall enjoyment of life (AAPA). The ketogenic diet (KD) is a high fat, low carbohydrate dietary regimen, which is described to decrease neuronal excitation, increase ketone bodies and ATP levels, while lowering glucose and proinflammatory cytokines. The KD is an effective therapy for epilepsy; a disorder that arises from either lowered inhibition or increased excitation, similar to ...
Modulatory Actions Of Serotonergic System In Cardiac Function, Behavior, And Sensorimotor Circuit Activity In Drosophila Melanogaster, Zana R. Majeed
Theses and Dissertations--Biology
In this dissertation, I have focused on the role of serotonin (5-HT) as a modulator in heart rate, feeding and locomotion behaviors as well as sensorimotor circuit activity in Drosophila melanogaster. A general overview in the actions of the serotonergic (5-HTergic) system on the larval heart and nervous system in larvae and adults is reviewed in Chapter One. I sought to further study the actions of serotonergic system to provide additional insights into cellular and molecular underpinnings in the actions of 5-HT.In Chapter two, I present studies on mechanisms of action by 5-HT in larvae cardiac system. For this ...
Role Of The Chondroitin Sulfate Proteoglycan, Neurocan, In Inhibition Of Sensory Neurite Regeneration, 2016 University of Kentucky
Role Of The Chondroitin Sulfate Proteoglycan, Neurocan, In Inhibition Of Sensory Neurite Regeneration, Madison Klump
Honors Program Senior Capstone Collection
In the adult mammalian brain and spinal cord, neuronal injury results in failed neurite regeneration, in part due to the up-regulation of chondroitin sulfate proteoglycans (CSPGs). CSPGs are molecules consisting of a protein core with covalently bound glycosaminoglycans (GAGS), specifically, chondroitin sulfate side-chains. The majority of CSPGs produced after injury originate from reactive astrocytes found in the glial scar surrounding the injury site. Although this milieu is very complex and involves more than just CSPGs, axonal regrowth may be improved if the expression of specific, highly inhibitory CSPGs produced after injury were attenuated selectively. Neurocan is one type of CSPG ...
Exercise During The Juvenile Period Produces Long Lasting Stress Protection Potentially Subserved By Epigenetic Alterations To The Serotonergic System, 2016 University of Colorado, Boulder
Exercise During The Juvenile Period Produces Long Lasting Stress Protection Potentially Subserved By Epigenetic Alterations To The Serotonergic System, Nicole L. Rumian
Undergraduate Honors Theses
Exercise is capable of producing a myriad of beneficial alterations in brain chemistry and function which can help prevent stress-related psychiatric disorders, such as anxiety and depression. Recent work from our lab demonstrates that 6 weeks of exercise initiated in early life produces lasting protection against stress-induced anxiety and depressive like behaviors, whereas, in adults, this protection is transient and dissipates upon cessation of exercise. Thus, when exercise begins at a young age, the neurobiological improvements remain intact even after exercise has ceased for a period of time. The mechanism underlying this long lasting protection is currently unknown. Furthermore, it ...
Methylation Of The Brain Derived Neurotrophic Factor Gene In Alcohol Use Disorder, 2016 University of Colorado, Boulder
Methylation Of The Brain Derived Neurotrophic Factor Gene In Alcohol Use Disorder, Timothy B. Helmuth
Undergraduate Honors Theses
Background: Alcohol use disorder (AUD) is a significant health problem in the U.S. Specifically, AUD is associated with memory problems and other cognitive defects. DNA methylation of CpG sites and other epigenetic factors have been found to play an important role in the development of Alcohol Use Disorders (AUD). Because of this, it was hypothesized that individuals with AUD would show differential methylation in neurotrophic factors, specifically, the BDNF gene, as compared to controls.
Methods: Precuneus brain tissue from 49 Alcohol Use Disorder cases and 47 controls were obtained from the New South Wales and Victorian Tissue Resource ...
Axon Initial Segment Loss Is Not Observed In The Hippocampus Of A Experimental Autoimmune Encephalomyelitis Mouse Model, 2016 Virginia Commonwealth University
Axon Initial Segment Loss Is Not Observed In The Hippocampus Of A Experimental Autoimmune Encephalomyelitis Mouse Model, Praveen Mohanraju
Undergraduate Research Posters
The axon initial segment (AIS) is fundamental for neuronal communication and action potential initiation, a characteristic which has been shown to be disrupted in inflammatory diseases such as Multiple Sclerosis (MS). Previous work from our lab has shown AIS breakdown in layer 5 of the cortex in a mouse model of MS known as experimental autoimmune encephalomyelitis (EAE). Moreover, it was shown that AIS breakdown was independent of demyelination but temporally correlated with microglial inflammatory reactivity. In order to determine if this pathology is specific to the cortex or affects other regions of the brain, we exploited these EAE induced ...
Mapping Sensorimotor Circuits In The Hindbrain Of Xenopus Laevis Tadpoles, 2016 Bard College
Mapping Sensorimotor Circuits In The Hindbrain Of Xenopus Laevis Tadpoles, Clara Evelyn Woolner
Senior Projects Spring 2016
Mapping neural connections within the brain allows us to understand not only how it is organized, but also how it functions. By studying the individual neurons which comprise these neural circuits, we are able to determine how activity at the cellular level translates into a specified process or behavior. The Mauthner cells, which initiate a characteristic startle behavior in teleost fish and amphibians, are ideal subjects for the study of sensorimotor networks and neural plasticity. I used a fluorescent retrograde dye to label neurons involved in locomotion in the hindbrain of Xenopus laevis tadpoles. The Mauthner cells, reticulospinal cells, and ...
Lack Of Neocortex Does Not Imply Fish Cannot Feel Pain, 2016 University of California, Irvine
Lack Of Neocortex Does Not Imply Fish Cannot Feel Pain, Georg Striedter
Animal Sentience: An Interdisciplinary Journal on Animal Feeling
Some contemporary scientists are using comparative neurobiological data to argue that non-mammalian vertebrates have feelings, most notably of pain (e.g., Braithwaite, 2010; Mashour and Alkire, 2012), while Key (2016) uses the same general data to reach the opposite conclusion. In a nutshell, he argues that fish cannot feel pain because fish don’t have a neocortex, which humans need to consciously experience pain. I don’t know how these scientists can look at essentially the same data and reach such disparate conclusions, but I suspect that some of them have strong a priori beliefs and, therefore, view the data ...

Compensatory Mechanisms And T Cell Migration In Mouse Models Of Dopaminergic Loss, 2015 University of Nebraska Medical Center
Compensatory Mechanisms And T Cell Migration In Mouse Models Of Dopaminergic Loss, Kristi M. Anderson
Theses & Dissertations
Parkinson’s disease (PD) is the most common neurodegenerative movement disorder and second most common neurodegenerative disorder. PD is characterized by the selective loss of dopaminergic neurons and dopamine neurotransmitter within the substantia nigra and termini in the striatum. Progressive loss of dopaminergic neurons occurs over many years in PD, and by the time movement disorder symptoms manifest, up to 50-70% of dopaminergic neurons have been lost. Several aspects of PD pathology have been described in detail, but a better understanding of PD progression is needed to develop more efficient treatments.
Motor symptoms associated with PD do not manifest until ...
Development Of Manganese-Enhanced Magnetic Resonance Imaging (Memri) Methods To Study Pathophysiology Underlying Neurodegenerative Diseases In Murine Models, 2015 University of Nebraska Medical Center
Development Of Manganese-Enhanced Magnetic Resonance Imaging (Memri) Methods To Study Pathophysiology Underlying Neurodegenerative Diseases In Murine Models, Aditya N. Bade
Theses & Dissertations
Manganese-enhanced magnetic resonance imaging (MEMRI) opens the great opportunity to study complex paradigms of central nervous system (CNS) in freely behaving animals and reveals new pathophysiological information that might be otherwise difficult to gain. Due to advantageous chemical and biological properties of manganese (Mn2+), MEMRI has been successfully applied in the studies of several neurological diseases using translational animal models to assess comprehensive information about neuronal activity, morphology, neuronal tracts, and rate of axonal transport. Although previous studies highlight the potential of MEMRI for brain imaging, the limitations concerning the use of Mn2+ in living animals and applications ...
Deep Brain Stimulation And Its Effects On Parkinson Disease Spatiotemporal Gait Parameters., 2015 The University of Western Ontario
Deep Brain Stimulation And Its Effects On Parkinson Disease Spatiotemporal Gait Parameters., Greydon Gilmore
Electronic Thesis and Dissertation Repository
Subthalamic (STN) deep brain stimulation (DBS) alleviates common appendicular PD symptoms, such as: tremor, rigidity and bradykinesia. However, the effect STN-DBS has on modulating axial gait features has not been properly quantified objectively. The purpose of the present thesis was to investigate the role STN-DBS plays in modulating specific gait features such as pace, asymmetry, variability, rhythm and postural control. It is hypothesized that axial gait function is regulated predominantly by non-dopaminergic control systems. In the acute immediate post-operative phase a surgical effect, named the microlesion effect (MLE), is thought to produce a transient improvement of appendicular and axial symptoms ...
Characterizing The Rogfp2-Orp1 Fluorescent Biosensor For Detecting Oxidative Stress In Mammalian Cells, Sara A. Doan, Stevie Norcross, Mathew Tantama
The Summer Undergraduate Research Fellowship (SURF) Symposium
Parkinson’s disease is a neurodegenerative disease involving the death of neurons in the substantia nigra and loss of the neurotransmitter, dopamine. The disease leads to progressive loss of motor control. Exact causes and mechanisms by which Parkinson’s disease proceeds are unknown, however, previous experiments determine oxidative stress in mitochondria as a factor that results in cell death. Strategies have been implemented to generate fluorescent biosensors to monitor reactive oxygen species (ROS) concentrations while simultaneously measuring the spatiotemporal distribution and correlation between the ROS, cellular function and organelle. Orp1, an enzyme found in yeast, is a sensitive oxidizing species ...
The Concept Of Qailulah (Midday Napping) From Neuroscientific And Islamic Perspectives, 2015 University of Malaya
The Concept Of Qailulah (Midday Napping) From Neuroscientific And Islamic Perspectives, Mohd Tumiran
Mohd Amzari Tumiran
Napping/siesta during the day is a phenomenon which is widely practised in the world. However, the timing, frequency and duration may vary. The basis of napping is also diverse, but it is mainly done for improvement of alertness and general well-being. Neuroscience reveals that midday napping improves memory, enhances alertness, boosts wakefulness and performance, and recovers certain qualities of lost night sleep. Interestingly, Islam, the religion of the Muslims, advocates midday napping primarily because it was a practice preferred by Prophet Muhammad (pbuh). The objectives of this review are to investigate and compare identical key points on focused topic ...
Quantifying The Effects Of Systematic Stn-Dbs Programming On Rest And Postural Tremor In Idiopathic Parkinson Disease Patients, 2015 The University of Western Ontario
Quantifying The Effects Of Systematic Stn-Dbs Programming On Rest And Postural Tremor In Idiopathic Parkinson Disease Patients, Kristina Ognjanovic
Electronic Thesis and Dissertation Repository
Parkinson’s disease (PD) is a complex neurodegenerative disorder that encompasses both motor and non-motor symptoms. These symptoms and their severity are typically assessed by scale based measures in a clinical setting. Scale- based assessments of PD patients undergoing bilateral subthalamic nucleus deep brain stimulation surgery (STN-DBS) such as the Unified Parkinson Disease Rating Scale (UPDRS) are commonly used in a clinical setting to assess symptom severity and progression. However, the subjective nature of these and other clinical scales call into question both the sensitivity and accuracy of patient assessment over time. An objective quantification of rest and postural tremor ...
