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

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

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 …
