Cromwell Relative Reward Striatal Activity.Pdf, Howard C. Cromwell, Emily S. Webber, David E. Mankin

Howard Casey Cromwell

The striatum is a key brain region involved in reward processing. Striatal activity has been linked to encoding rewardmagnitude and integrating diverse reward outcome information. Recent work has supported the involvement ofstriatum in the valuation of outcomes. The present work extends this idea by examining striatal activity during dynamicshifts in value that include different levels and directions of magnitude disparity. A novel task was used to produce
diverse relative reward effects on a chain of instrumental action. Rats (Rattus norvegicus) were trained to respond to
cues associated with specific outcomes varying by food pellet magnitude. Animals were exposed to single-outcomesessions ...


Adult Neurogenesis In Avian Auditory Cortex, Caudomedial Nidopallium (Ncm): Lateralization And Effects Of Statins, Shuk C. Tsoi 2016 The Graduate Center, City University of New York

Adult Neurogenesis In Avian Auditory Cortex, Caudomedial Nidopallium (Ncm): Lateralization And Effects Of Statins, Shuk C. Tsoi

All Graduate Works by Year: 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 ...


The Evolutionary History Of Consciousness, Eirik Søvik, Clint Perry 2016 Volda University College

The Evolutionary History Of Consciousness, Eirik Søvik, Clint Perry

Animal Sentience: An Interdisciplinary Journal on Animal Feeling

Klein & Barron argue that insects are capable of subjective experience, i.e., sentience. Whereas we mostly agree with the conclusion of their arguments, we think there is an even more important message to be learned from their work. The line of reasoning opened by Klein & Barron proves instructive for how neuroscientists can and should explore the biological phenomenon of consciousness.


Dyslexia And Language Impairment Associated Genetic Markers Influence Cortical Thickness And White Matter In Typically Developing Children, John D. Eicher, Jean A. Frazier, David N. Kennedy, Jeffrey R. Gruen 2016 Yale University

Dyslexia And Language Impairment Associated Genetic Markers Influence Cortical Thickness And White Matter In Typically Developing Children, John D. Eicher, Jean A. Frazier, David N. Kennedy, Jeffrey R. Gruen

Jean A. Frazier

Dyslexia and language impairment (LI) are complex traits with substantial genetic components. We recently completed an association scan of the DYX2 locus, where we observed associations of markers in DCDC2, KIAA0319, ACOT13, and FAM65B with reading-, language-, and IQ-related traits. Additionally, the effects of reading-associated DYX3 markers were recently characterized using structural neuroimaging techniques. Here, we assessed the neuroimaging implications of associated DYX2 and DYX3 markers, using cortical volume, cortical thickness, and fractional anisotropy. To accomplish this, we examined eight DYX2 and three DYX3 markers in 332 subjects in the Pediatrics Imaging Neurocognition Genetics study. Imaging-genetic associations were examined by ...


Insects Have The Capacity For Subjective Experience, Colin Klein, Andrew B. Barron 2016 Macquarie University, Australia

Insects Have The Capacity For Subjective Experience, Colin Klein, Andrew B. Barron

Animal Sentience: An Interdisciplinary Journal on Animal Feeling

To what degree are non-human animals conscious? We propose that the most meaningful way to approach this question is from the perspective of functional neurobiology. Here we focus on subjective experience, which is a basic awareness of the world without further reflection on that awareness. This is considered the most basic form of consciousness. Tellingly, this capacity is supported by the integrated midbrain and basal ganglia structures, which are among the oldest and most highly conserved brain systems in vertebrates. A reasonable inference is that the capacity for subjective experience is both widespread and evolutionarily old within the vertebrate lineage ...


Encoding Of Saltatory Tactile Velocity In The Adult Orofacial Somatosensory System, Rebecca Custead 2016 University of Nebraska-Lincoln

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

Public Access Theses and Dissertations from the College of Education and Human Sciences

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 ...


Examination Of Methamphetamine Reinstatement In Female And Male Rats: A Pre-Clinical Model Of Relapse, Steven T. Pittenger 2016 University of Nebraska-Lincoln

Examination Of Methamphetamine Reinstatement In Female And Male Rats: A Pre-Clinical Model Of Relapse, Steven T. Pittenger

Theses, Dissertations, and Student Research: Department of Psychology

Methamphetamine (meth) dependence is often characterized by persistent and chronic relapse (i.e., return to drug use). There is growing pre-clinical and human evidence suggesting females are at greater risk to relapse. The set of studies presented in this dissertation extended this limited evidence by identifying sex-dependent neural substrates correlated with meth-triggered reinstatement (Experiment 1) and by examining sex-differences in reinstatement triggered by drugs of abuse that are commonly co-abused with meth (Experiment 2). Female and male rats were trained to self-administer meth, received subsequent extinction sessions, and then tested for reinstatement. In Experiment 1, rats were perfused following reinstatement ...


The Effects Of Lipopolysaccharide-Induced Neuroinflammation On Learning And Forgetting In Juvenile Rats, Michele Barry 2016 Seton Hall University

The Effects Of Lipopolysaccharide-Induced Neuroinflammation On Learning And Forgetting In Juvenile Rats, Michele Barry

Seton Hall University Dissertations and Theses (ETDs)

The inability to remember events experienced very early in life is referred to as Infantile Amnesia (IA) and has been observed in both humans and animals. Over the years interest in the phenomenon waned, but has recently increased with the discovery of new neurobiological methods to study brain function (e.g., Callaghan, Li & Richardson, 2014). The neurobiological mechanism behind IA has yet to be determined, but several innovative theories have been developed with these new research methods. The neurogenesis hypothesis theorizes that increased neurogenesis during early development disrupts previously established memories. The hippocampus, an area that mediates both the memory ...


Comparative Evolutionary Approach To Pain Perception In Fishes, Culum Brown 2016 Macquarie University

Comparative Evolutionary Approach To Pain Perception In Fishes, Culum Brown

Culum Brown

Arguments against the fact that fish feel pain repeatedly appear even in the face of growing evidence that they do. The standards used to judge pain perception keep moving as the hurdles are repeatedly cleared by novel research findings. There is undoubtedly a vested commercial interest in proving that fish do not feel pain, so the topic has a half-life well past its due date. Key (2016) reiterates previous perspectives on this topic characterised by a black-or-white view that is based on the proposed role of the human cortex in pain perception. I argue that this is incongruent with our ...


Histological Verification Of Electrode Placement In Single Unit Recorded Rats, Dana Lew 2016 University of Connecticut - Storrs

Histological Verification Of Electrode Placement In Single Unit Recorded Rats, Dana Lew

Honors Scholar Theses

The hippocampus is a region of the brain which plays a major role in encoding spatial and episodic memory. The hippocampus is divided in to two main subregions, dorsal and ventral. These subregions are connected, but their functional organization remains widely unknown. Place cells are cells of the hippocampus which fire in a specific spatial area and help create a mental map of our surroundings. Place cells have been seen to remain constant during slight fluctuations in surroundings, but completely remap in response to large fluctuations in the environment. There is little known about the relatively few place cells in ...


The Influence Of Canine Aggression And Behavioral Treatment On Heart Rate Variability, Lydia Craig 2016 Macalester College

The Influence Of Canine Aggression And Behavioral Treatment On Heart Rate Variability, Lydia Craig

Psychology Honors Projects

Dog aggression affects many, with nearly 5 million dog bites reported yearly in the United States alone. With the physical, emotional, and monetary costs of bites, it is of considerable interest to identify dogs that are likely to bite. One physiological measure that might serve as an index of aggression is heart rate variability (HRV), which refers to vagally mediated beat-to-beat change in heart rate. Low HRV has been associated with impaired emotional and behavioral regulation and stress in both humans and animals. To assess whether this measure corresponds with aggression in dogs, resting HRV was measured for dogs with ...


Sexism Goes Underground: The Development Of A Neosexism Scale Catered To College Student Populations, Kayla A. Huber 2016 Lake Forest College

Sexism Goes Underground: The Development Of A Neosexism Scale Catered To College Student Populations, Kayla A. Huber

Senior Theses

Cultural and political changes in the last century have made it largely socially unacceptable to overtly discriminate against women. Such pressures may have forced sexist beliefs to be expressed in more covert forms. This study aimed to develop a psychometric scale that assesses such covert, or neosexist, beliefs in college student populations and to analyze the relationship between neosexism and gender egalitarian beliefs, feminist awareness, social desirability, and an existing scale of neosexism. Similar to previous research, a series of exploratory and confirmatory factor analyses yielded a one-factor model of neosexism. This model was invariant across gender and race. Scores ...

Neural Integration Underlying A Time-Compensated Sun Compass In The Migratory Monarch Butterfly, Eli Shlizerman, James Phillips-Portillo, Daniel B. Forger, Steven M. Reppert 2016 University of Washington - Seattle

Neural Integration Underlying A Time-Compensated Sun Compass In The Migratory Monarch Butterfly, Eli Shlizerman, James Phillips-Portillo, Daniel B. Forger, Steven M. Reppert

Open Access Articles

Migrating eastern North American monarch butterflies use a time-compensated sun compass to adjust their flight to the southwest direction. Although the antennal genetic circadian clock and the azimuth of the sun are instrumental for proper function of the compass, it is unclear how these signals are represented on a neuronal level and how they are integrated to produce flight control. To address these questions, we constructed a receptive field model of the compound eye that encodes the solar azimuth. We then derived a neural circuit model that integrates azimuthal and circadian signals to correct flight direction. The model demonstrates an ...

Biomedical Engineering Faculty Research Publications

Spontaneous fluctuations of resting state functional MRI (rsfMRI) have been widely used to understand the macro-connectome of the human brain. However, these fluctuations are not synchronized among subjects, which leads to limitations and makes utilization of first-level model-based methods challenging. Considering this limitation of rsfMRI data in the time domain, we propose to transfer the spatiotemporal information of the rsfMRI data to another domain, the connectivity domain, in which each value represents the same effect across subjects. Using a set of seed networks and a connectivity index to calculate the functional connectivity for each seed network, we transform data into ...


The Influence Of Cues And Beacons On Route Memory, Obaiy Fahmy 2016 Lake Forest College

The Influence Of Cues And Beacons On Route Memory, Obaiy Fahmy

Senior Theses

Part-set cueing facilitation refers to the retrieval advantage when part of the set of to-be-remembered information is provided as cues at test. The present experiments were designed to explore part-set cueing in the context of map and route memory. In two experiments, we set out to find how cues and beacons would affect the recall of routes, as well as to see if presentation during the memorization phase changed the outcome in the recall task. The use of both beacons and part-set cues facilitates the recall of routes, but to varying degrees. Implications of these findings will be discussed.


Cannabinoid Cb1 Transmission In The Mesolimbic Reward Pathway, Tasha Ahmad 2016 The University of Western Ontario

Cannabinoid Cb1 Transmission In The Mesolimbic Reward Pathway, Tasha Ahmad

Electronic Thesis and Dissertation Repository

Cannabinoid CB1 receptor (CB1R) transmission within the mesocorticolimbic system plays an important role in forming associative memories, and processing both positive and negative experiences. Opiates generally produce potent rewarding effects and previous evidence suggests that CB1 transmission may modulate the neural reward circuitry involved in opiate reward processing. The ventral tegmental area (VTA), medial prefrontal cortex (mPFC), basolateral amygdala (BLA), and Nucleus Accumbens (NA) are all implicated in opiate-reward processing, contain high levels of CB1 receptors, and are all modulated by dopamine (DA). Although, CB1 transmission within these areas has been heavily implicated in associative memory and learning, the potential ...
