The Pribram – Bohm Hypothesis Part Ii: The Physiology Of Consciousness, Shelli R. Joye

CONSCIOUSNESS: Ideas and Research for the Twenty-First Century

A physiology of consciousness is elaborated, based upon implications of the Pribram-Bohm hypothesis (developed in Part I of this series). The model presented here is in sharp contrast to the prevailing conviction among neuroscientists that consciousness will eventually be discovered to be a physiological epiphenomenon of neuronal electrical impulses firing in the brain. In contrast, the Pribram-Bohm theory holds that consciousness, inherent in what Bohm views cosmologically as “the Whole,” manifests as a dynamic conscious energy resonance bridging the explicate space-time domain with the nonlocal, transcendent flux domain termed the “implicate order.” Presented in Part I, the Pribram-Bohm hypothesis posits …

Role Of Anterior Cingulate Cortex In Saccade Control, Sahand Babapoor-Farrokhran

Electronic Thesis and Dissertation Repository

Cognitive control is referred to the guidance of behavior based on internal goals rather than external stimuli. It has been postulated that prefrontal cortex is mainly involved in higher order cognitive functions. Specifically, anterior cingulate cortex (ACC), which is part of the prefrontal cortex, is suggested to be involved in performance monitoring and conflict monitoring that are considered to be cognitive control functions.

Saccades are the fast eye movements that align the fovea on the objects of interest in the environment. In this thesis, I have explored the role of ACC in control of saccadic eye movements. First, I performed …

The Neuroprotective Effects Of Endurance Training On The Aging Brain, Katelyn Norton

Electronic Thesis and Dissertation Repository

Dysregulation of autonomic control often develops with advancing age, favoring a chronic state of heightened sympathetic outflow with parasympathetic withdrawal. However, the mechanisms of this age-related autonomic impairment are not known and may relate to alterations in brain structure (e.g. cortical atrophy) and/or altered neural function, particularly in regions related to the cortical autonomic network, namely, the medial prefrontal cortex (MPFC), insula cortex (IC), and hippocampus (HC). Exercise exerts beneficial effects on brain structure and, in the case of cognition, neurologic function; however, how exercise affects regions of the brain related to autonomic function are not known. This thesis tested …

Synthetic And Biological Exploration Of (+)-Boldine - Identification Of Potential Cns Receptor Ligands, Sujay Joseph

Theses and Dissertations

(+)-Boldine, an aporphine alkaloid, is reported to be biologically active at various Central Nervous System(CNS) receptors. However, only a few Structure Activity Relationship(SAR) studies have been conducted using boldine’s aporphine scaffold. A library of novel analogs was synthesized from boldine to understand the effect of bisbenzylation at C2 and C9 positions on the affinity and selectivity at the serotonin receptors.

Unravelling The Subfields Of The Hippocampal Head Using 7-Tesla Structural Mri, Jordan M. K. Dekraker

Electronic Thesis and Dissertation Repository

Probing the functions of human hippocampal subfields is a promising area of research in cognitive neuroscience. However, defining subfield borders in Magnetic Resonance Imaging (MRI) is challenging. Here, we present a user-guided, semi-automated protocol for segmenting hippocampal subfields on T2-weighted images obtained with 7-Tesla MRI. The protocol takes advantage of extant knowledge about regularities in hippocampal morphology and ontogeny that have not been systematically considered in prior related work. An image feature known as the hippocampal ‘dark band’ facilitates tracking of subfield continuities, allowing for unfolding and segmentation of convoluted hippocampal tissue. Initial results suggest that this protocol offers sufficient …

Spider Brain Morphology & Behavior, Skye M. Long

Doctoral Dissertations

Spiders are ideal model animals for experimental and comparative studies of behavior, learning and perception. They display many complex behaviors, such as the multimodal mating dances of lycosid spiders, the stealthy hunting strategies of the jumping spider Portia sp., to the labile sociality of theridiids. Spiders also demonstrate a wide range of cognitive capabilities. Spiders perceive their environment using multiple sensory modalities including: chemosensory organs; lyriform and slit-sense organs and specialized hairs that detect vibration and air movement; and up to eight eyes that vary in function, some able to detect polarization and a broad spectrum of light, including …

Encoding Of Saltatory Tactile Velocity In The Adult Orofacial Somatosensory System, Rebecca Custead

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Processing dynamic tactile inputs is a key function of somatosensory systems. Spatial velocity encoding mechanisms by the nervous system are important for skilled movement production and may play a role in recovery of motor function following neurological insult. Little is known about tactile velocity encoding in trigeminal networks associated with mechanosensory inputs to the face, or the consequences of movement.

High resolution functional magnetic resonance imaging (fMRI) was used to investigate the neural substrates of velocity encoding in the human orofacial somatosensory system during unilateral saltatory pneumotactile inputs to perioral hairy skin in 20 healthy adults. A custom multichannel, scalable …

Developing A Data Repository Of Standard Concussion Assessment Clinical Data For Research Involving College Athletes, Arthur C. Maerlender, Jennifer Mize Nelson, Julie A. Honaker

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

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 …

The Role Of Daf-19 In Non-Ciliated Neurons: How Is Neural Development Regulated By Different Daf-19 Isoforms?, Zabdiel Ek Vazquez

Lawrence University Honors Projects

A degenerative disease-like phenotype, specifically reduction in synaptic protein levels in adult worms, is correlated with loss-of-function of the only RFX transcription factor gene, daf-19, in C. elegans. This gene encodes four known transcription factor isoforms, two of which are correlated with particular functions. The DAF-19C isoform activates genes responsible for cilia development, while DAF-19M is needed for cilia specification in males. A comparison of the transcriptome of daf-19 null and isogenic wild type adult worms suggests both positive and negative regulation of gene expression is correlated with the presence of DAF-19 proteins. We have assessed DAF-19 regulation …

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 ketogenic diet …

The Relationship Between Time Of Day, Mood, And Electroencephalography (Eeg) Asymmetry, Morgan Tantillo

Honors Projects

Previous researchers have had success in finding a correlation between exercise and an increase in positive mood. Researchers have also found a correlation between time of day and mood. The current study will explore the relationship between time of day, mood, and electroencephalography (EEG) asymmetry. The study utilized a convenient sample of ten undergraduate students at Bowling Green State University. Participants had baseline EEG recordings taken, and then participated in moderate exercise, followed by another EEG recording. Participants’ mood was assessed through a self-reported mood questionnaire before the condition as well as immediately after. Due to multiple statistical tests, the …

Anatomical Markers For Elevated Cognition In Dinosaurs, Thomas Gaetano

Honors Projects

Much research has been conducted on brain evolution within Dinosauria. Dinosaurs were originally believed to be incapable of any advanced cognitive abilities beyond the level observed in modern reptiles. This is likely true for many dinosaurs, but recent discoveries suggest that the non-avian maniraptor dinosaurs shared many physical characteristics with their bird descendants, including body feathers and neural adaptations for flight. By studying cranial endocasts (the braincase of fossilized skulls) using computed tomography (CT), paleontologists are beginning to understand the neural changes that took place across the dinosaur-bird transition. Most of these studies are focused on the development of flight, …

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 …
