Cerebellum-Seeded Functional Connectivity Changes In Trait-Anxious Individuals Undergoing Attention Bias Modification Training, Katherine Elwell Jul 2021

Cerebellum-Seeded Functional Connectivity Changes In Trait-Anxious Individuals Undergoing Attention Bias Modification Training, Katherine Elwell

All NMU Master's Theses

Anxiety and anxiety related disorders are increasing at a drastic rate in the past decade, with the NIMH reporting that 31.1% of U.S. adults will experience an anxiety disorder at some point in their lives. Anxiety is commonly characterized by increased attention bias to threat. Attention Bias Modification (ABM) is a new treatment used to reduce individual’s attention bias towards threat. The extent to which ABM leads to underlying neural changes is still unknown. The cerebellum is a neglected brain structure, with new research provides evidence that cerebellum’s functional connectivity and shared networks with threat processing regions has a direct …


Intracranial Infusions Of Neurotensin Agonists Produce An Anxiolytic Profile In A Rat Ultrasonic Vocalization Model, Floyd F. Steele Iii Aug 2015

Intracranial Infusions Of Neurotensin Agonists Produce An Anxiolytic Profile In A Rat Ultrasonic Vocalization Model, Floyd F. Steele Iii

Neurotensin (NT) is a peptide neurotransmitter that interacts with brain monoamine neurotransmitter systems. It has been demonstrated that neurotensin type 1 and type 2 receptor agonists influence animal models of psychological disorders and pain regulation, respectively. It has already been shown that the systemic administration of the selective neurotensin type 1 receptor agonist PD149163 can attenuate the number of fear-induced 22-kHz ultrasonic vocalizations (USVs) produced by male Wistar rats. A reduction in the number of 22-kHz USV calls is indicative of an anxiolytic effect. The current study used a USV model to evaluate the effects of PD149163 (0.1, 1.0, and …
