Assessment Of Executive Function Using A Series Of Operant Conditioning Based Tasks In T1dm Rodents, Kevin T. Murphy
Assessment Of Executive Function Using A Series Of Operant Conditioning Based Tasks In T1dm Rodents, Kevin T. Murphy

This study examined the impact of Type 1 Diabetes Mellitus (T1DM) on executive function using a series of operant conditioning based tasks in rats. Sprague Dawley rats were randomized to either non-diabetic (n = 12; 6 male) or diabetic (n = 14; 6 male) groups. Diabetes was induced using multiple low-dose streptozotocin injections. All diabetic rodents were insulin-treated using subcutaneous insulin pellet implants. At week 14 of the study, rats were placed on a food restricted diet to induce 5 - 10% weight loss. Rodents were familiarized and tested on a series of tasks that required continuous adjustments to novel …

Functional Loss Of Cntnap2 In The Rat Leads To Autism-Related Alterations In Behaviour And Auditory Processing, Kaela Elizabeth Scott

The contactin-associated protein-like 2 gene, CNTNAP2, is a highly penetrant gene thought to play a role in the genetic etiology of neurodevelopmental disorders such as autism spectrum disorder (ASD). Despite its link to ASD, the field lacks a complete understanding of the role CNTNAP2 plays in the hallmarks of ASD: repetitive behaviours and abnormalities in social interaction, language, and sensory processing. Therefore, this thesis first examines if a loss-of-function mutation in the CNTNAP2 gene in the rat (SD-Cntnap2tm1Sage) is sufficient to cause alterations in social interactions, stereotypic behaviour, and sensory processing. Cntnap2 knockout rats showed deficits …
