Autism spectrum disorder (ASD) is a neurodevelopmental disorder that is characterized by a subset of symptoms known as restricted repetitive behaviors (RRBs). RRBs are categorized into both lower order and higher order RRBs, where the latter can be described as behavioral inflexibility. The BTBR T+ tf/J (BTBR) mouse strain has been an extensively used animal model that demonstrate the behavioral symptoms of these individuals, including inflexible behavior. Currently, there are few effective treatments for individuals with ASD that express RRBs. Past research has investigated treatments that target serotonin due its historic involvement in ASD. 8-OH-DPAT (8-hydroxy-2-(di-n-propylamine) tetralin) is a research …
The Role Of 5-Ht6 Receptor Activation In Learning Consolidation, Jasmine Alyssa Robinson
The Role Of 5-Ht6 Receptor Activation In Learning Consolidation, Jasmine Alyssa Robinson
Electronic Theses, Projects, and Dissertations
The focus on serotonergic dysfunction as a contributor to cognitive deficits in disorders such as autism spectrum disorder, Alzheimer's disease, and schizophrenia drives researchers to investigate the functional impact of specific serotonin receptor types on executive functioning. By discerning the potential enhancement or impairment effects, this endeavor seeks to unravel the complex interplay between serotonin receptors and cognitive abilities. Specifically, within the three domains of learning, acquisition, consolidation, and retrieval, we find serotonergic modulation to be pivotal. Recent studies have highlighted the 5-HT6 receptor as a novel target for cognitive enhancement. However, the majority of the research investigates the effects …

Escitalopram (EST), a selective serotonin reuptake inhibitor (SSRI), is an antidepressant frequently used during pregnancy, yet there is limited knowledge of its long-term effects on maternal use. Past studies suggest that maternal exposure may adversely affect the fetus, which may be due to the hyperserotonergic environment caused by the nature of SSRIs during early development. Modifications of the serotonergic system in offspring during certain critical periods of development may result in long-term behavioral and cognitive changes in adulthood. Further, recent human studies have demonstrated that prenatal exposure to SSRIs in humans may increase susceptibility to autism spectrum disorder (ASD) and …
Serotonin 1b/1a Receptor Modulation On Behavioral Flexibility In C57bl/6j Mice, Brandon L. Oliver

Pharmacological activation of the 5-HT1B and 1A receptors has been implicated in OCD-like behaviors in rodents such as increased perseverative circling, checking behaviors, and locomotor stereotypy. However, little is understood about the effects of 5-HT1B and 1A receptor activation on behavioral inflexibility, a common symptom associated with OCD. The present study utilized the 5-HT1B/1A receptor agonist RU24969 at 0.01, 0.1, and 1.0 mg/kg to test three hypotheses. The first hypothesis predicted RU24969 would lead to a dose-dependent impairment on behavioral flexibility in C57BL/6J mice. It was also predicted that male C57BL/6J mice would be more inflexible than female C57BL/6J mice …
