Protein Kinase M Zeta-Mediated Ltp Maintenance In The Non-Human Primate Hippocampus: A Role For Stress And Serotonergic Signaling In Affective Processing, Sasha L. Fulton
Protein Kinase M Zeta-Mediated Ltp Maintenance In The Non-Human Primate Hippocampus: A Role For Stress And Serotonergic Signaling In Affective Processing, Sasha L. Fulton
Theses and Dissertations
Early-Life Stress (ELS) is associated with vulnerability to mood disorder, but it’s not well understood how ELS contributes to deficits in cognitive function. Atypical PKMzeta is critical for LTP maintenance and memory. The current study aims to characterize the ELS phenotype with respect to this key marker of hippocampal LTP.

Neuromodulation is the practice of applying external stimulation, either electric or magnetic, to the human in order to affect positive change. TDCS or transcranial direct current stimulation is a neuromodulatory technique using a 9-volt battery. Because of the simplicity of the device, and it's relatively low potential for harm, the technique is popular with both researchers and at-home enthusiasts. To find out whether this technique works the way some people say it does, I built my own.
Examining Relationships Between Basic Emotion Perception And Musical Training In The Prosodic, Facial, And Lexical Channels Of Communication And In Music, Jamie Twaite
Dissertations, Theses, and Capstone Projects
Research has suggested that intensive musical training may result in transfer effects from musical to non-musical domains. There is considerable research on perceptual and cognitive transfer effects associated with music, but, comparatively, fewer studies examined relationships between musical training and emotion processing. Preliminary findings, though equivocal, suggested that musical training is associated with enhanced perception of emotional prosody, consistent with a growing body of research demonstrating relationships between music and speech. In addition, few studies directly examined the relationship between musical training and the perception of emotions expressed in music, and no studies directly evaluated this relationship in the facial …
Adult Neurogenesis In Avian Auditory Cortex, Caudomedial Nidopallium (Ncm): Lateralization And Effects Of Statins, Shuk C. Tsoi
Adult Neurogenesis In Avian Auditory Cortex, Caudomedial Nidopallium (Ncm): Lateralization And Effects Of Statins, Shuk C. Tsoi
Dissertations, Theses, and Capstone Projects
In the first part of this paper, we investigated the basic relationship between learning, memory and adult neurogenesis using zebra finches. We found that in the auditory cortex, the left hemisphere had more new neurons than the right hemisphere. This lateralization was correlated with song learning and memory. In the second part, we used juvenile zebra finches as a model organism to study the effects of Lipitor on learning, memory and neurogenesis. We found that Lipitor impaired song learning and memory storage. Lipitor treatments also changed the morphology of new neurons and size of old neurons, suggesting statins may affect …
Synthetic And Biological Exploration Of (+)-Boldine - Identification Of Potential Cns Receptor Ligands, Sujay Joseph
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.
Effect Of Cntf Derived Peptide, P021 On Cognition And Pathology In 3xtg-Ad Mouse Model Of Alzheimer's Disease, Narjes Baazaoui
Effect Of Cntf Derived Peptide, P021 On Cognition And Pathology In 3xtg-Ad Mouse Model Of Alzheimer's Disease, Narjes Baazaoui
Dissertations, Theses, and Capstone Projects
Studies described in this thesis deal with the preventive effects of a neurogenic/neurotropic peptidergic compound, P021, on neurogenesis and synaptic deficits, neurodegeneration, cognitive impairment, and Ab and tau pathologies in a 3xTg-AD mouse model of Alzheimer’s disease (AD).
Background: AD is a chronic progressive neurodegenerative disease. Its multifactorial nature and the heterogeneity make its treatment especially challenging. Although it is a major burden in society, at present there is no drug that can stop or slow down the progression of the disease. Currently, the only available treatments are symptomatic and for mild to severe stages. The development of a drug …
On The Screen, In The Mind: An Erp Investigation Into The Interaction Between Visuo-Spatial Information And Spatial Language During On-Line Processing, Emily Zane
Dissertations, Theses, and Capstone Projects
This project used Event-Related Potentials (ERPs) to explore neurophysiological brain responses to prepositional phrases involving concrete and abstract reference nouns (e.g., "plate" and "moment", respectively) after the presentation of objects with varying spatial features. Prepositional phrases were headed by in or on and were either matching (e.g., "in the plate/moment") or mismatching (e.g., "on the plate/moment"). Conjunction phrase matches and fillers were also presented. Before half of the concrete-phrase items, a photographic depiction of the reference noun was presented. In these photographs, objects were displayed in a way that was either more appropriate for in or for on. Similarly, before …
Messenger Rna Transport And Translation Regulated By The 3' Utrs Of Dendritic Mrnas And Abnormal Alternative Splicing Of Neuroligin1 In The Fmr1 Ko Mouse Hippocampus, Tianhui Zhu
Dissertations, Theses, and Capstone Projects
Fragile X Syndrome (FXS) is one of the most commonly inherited mental retardations. It is caused by the loss of functional fragile X mental retardation protein (FMRP). Loss of functional FMRP is the most widespread single-gene cause of autism. The most prominent phenotype of FXS patients is an IQ ranging from 20 to 70. FMRP is an RNA binding protein, widely expressed in almost all tissues and highly expressed in brain. As a RNA binding protein, 85-90 % of FMRP in the brain is associated with polyribosomes. Approximately 4 % of total mRNA is associated with FMRP, which functions in …
The Impact Of Affect On Neural Mechanisms Underlying Orientation Perception, Michelle L. Fowler
The Impact Of Affect On Neural Mechanisms Underlying Orientation Perception, Michelle L. Fowler
Dissertations, Theses, and Capstone Projects
The underlying mechanisms used to process 2D visual information to form a unified 3D percept of the world remain largely unknown. Previous work in our lab has shown that accurate 3D perception of textured surfaces depends on the presence of specific patterns of orientation flows in the retinal image. Recent research has shown that affective state may influence the visual perception of oriented patterns. Relative to neutral face stimuli, fearful face stimuli have been shown to increase sensitivity to orientation of low spatial frequency patterns and decrease sensitivity to orientation of high spatial frequency patterns. How affective state influences the …
Neurodevelopmental Defects Associated With Gestational Exposure To Low Levels Of Dbp In Mice, Françoise Sidime
Neurodevelopmental Defects Associated With Gestational Exposure To Low Levels Of Dbp In Mice, Françoise Sidime
Dissertations, Theses, and Capstone Projects
The etiology of autism is thought to involve the complex interplay among genetic and environmental factors. Patterns of inheritance suggest an epigenetic component to the development of autism. A variety of environmental risk factors are known to induce epigenetic changes in DNA, affecting many genes including those autism-associated genes (AAG). The plasticizer dibutyl phthalate (DBP; CAS 84-74-2) is a developmental and reproductive toxin that causes a broad range of birth defects resulting in neurological impairments.
To date, although the effect of DBP as an endocrine and a reproductive disruptor are established, there are only few studies that address the effects …
Status Signaling And The Characterization Of A Chirp-Like Signal In The Weakly Electric Fish Steatogenys Elegans, Caitlin E. Field
Status Signaling And The Characterization Of A Chirp-Like Signal In The Weakly Electric Fish Steatogenys Elegans, Caitlin E. Field
Dissertations, Theses, and Capstone Projects
Sensory systems are critical to both exploratory and communicatory processes, the study of which is critical to our understanding of how animals perceive and respond to their environments. In weakly electric fishes the electrosensory system is utilized for both of these purposes. One type of communication, status signaling, is widespread across taxa and frequently hormonally modulated. This hormonal modulation keeps the signal honest, wherein the status of the sender and the production of the status signal itself are both hormone dependent. We investigated exploratory and communicatory strategies of the electromotor system in pulse-type gymnotiforms, with a focus on status communication …
