The Effects Of Activity-Based Anorexia On The Rewarding Properties Of Methamphetamine And Wheel Running, Rachael M. Langa
The Effects Of Activity-Based Anorexia On The Rewarding Properties Of Methamphetamine And Wheel Running, Rachael M. Langa
Theses and Dissertations
An activity-based anorexia (ABA) paradigm in adolescent female mice was used to explore whether anorexia affects circuits underlying reward. The ABA paradigm significantly enhanced methamphetamine-induced conditioned place preference (CPP), but not wheel-induced CPP. These results indicate that the ABA paradigm enhances the rewarding properties of methamphetamine, but not wheel running.
The Effect Of Dopamine Blockade On Sensorimotor Gating In Social Phenotypes Of The African Cichlid Fish Astatotilapia Burtoni, Raymond A. Turco
The Effect Of Dopamine Blockade On Sensorimotor Gating In Social Phenotypes Of The African Cichlid Fish Astatotilapia Burtoni, Raymond A. Turco
Theses and Dissertations
We asked if blocking dopamine could improve implicit sensory gating deficits in a socially-defeated fish of a naturally-agonistic species. This study investigated the effects of dopamine D2R receptor antagonist metoclopramide on sensorimotor gating using a prepulse inhibition (PPI) paradigm in social phenotypes of male A. burtoni African cichlid fish.
Adult And Juvenile Rats Differentially Express Mpfc Glua2 Following Traumatic Memory Retrieval, Edgar Rodriguez
Adult And Juvenile Rats Differentially Express Mpfc Glua2 Following Traumatic Memory Retrieval, Edgar Rodriguez
Theses and Dissertations
To advance our understanding of how traumatic memories are modulated between adults and juveniles, we characterize the AMPAr subunits, GluA1, GluA2, GluA3 in the mPFC of rodents following traumatic memory retrieval.
GluA2 was differentially expressed in adults but not juveniles rats. There were no changes in GluA1 or GluA3 expression
Contextually Modulated Avoidance Behavior In Rats Post-Pavlovian Extinction, Lauren Branigan
Contextually Modulated Avoidance Behavior In Rats Post-Pavlovian Extinction, Lauren Branigan
Theses and Dissertations
The following study sought to examine the psychological substrates of renewal (e.g.., context dependent extinction processes) for conditioned avoidance behaviors in rats. Using signaled active avoidance conditioning, rats acquired two-way shuttle responding, to two different auditory stimuli. These behaviors were then extinguished through exposure to the auditory stimuli where shuttling behavior was now without consequence. Subjects were then tested for renewal of avoidance in three distinct renewal sequences (e.g., ABA vs ABB, AAB vs AAA, and ABC vs ABB) in three separate groups of rats. It was found that subjects showed more responding to a stimulus presented outside of its …
Methamphetamine-Induced Conditioned Place Preference In Adolescent Male And Female Mice Of Two Strains, Andre Bevil Toussaint
Methamphetamine-Induced Conditioned Place Preference In Adolescent Male And Female Mice Of Two Strains, Andre Bevil Toussaint
Theses and Dissertations
We used a conditioned place preference paradigm to test the rewarding effects of methamphetamine (1mg/kg) in adolescent male and female mice of two strains. We found that methamphetamine induced conditioned place preference in female C57Bl/6 and male 129/SvEv mice, but not female 129/SvEv or male C57Bl/6 mice.
An Analysis Of Canine Processing Of Stimulus Compounds Varying In Light And Sound Intensity, Katherine O. Compitus
An Analysis Of Canine Processing Of Stimulus Compounds Varying In Light And Sound Intensity, Katherine O. Compitus
Theses and Dissertations
A dog was trained to respond deferentially to two light-sound compounds. The dog was then tested with combinations of additional light and sound intensities. The dog appeared to use the information provided by both stimulus dimensions. This research is relevant to the understanding of information processing, specifically categorization and generalization.
