  1. Exploring the cardioprotective effect of synthetic wine in Long Evans rats

    Dlamini, LindizweDepartment of Medicine2015

    [No copyright notice] Background: Moderate and chronic consumption of red wine protects against cardiovascular disease. Wine is a complex matrix containing multiple molecules whose concentrations can vary from one bottle to another. Therefore, the delineation of the putative cardioprotective …

  6. Effects of Reticular Activation on Long-Term Depression in Primary Visual Cortex of the Long-Evans Rat

    Stewart, Matthew2018

    Long-term depression (LTD) is a widely studied form of activity-dependent synaptic plasticity, typically induced by prolonged low-frequency stimulation (LFS). LFS is highly effective in eliciting LTD in vitro, but several studies have failed to induce LTD using LFS in vivo, for reasons that remain …

  8. Exploring the Behavioural Effects of Compound-21 Using Novel Object Recognition and Object in Place Tests in Long Evans Rats

    Orvold, Spencer NeilUniversity of Saskatchewan2023

    Designer Receptors Exclusively Activated by Designer Drugs (DREADDs) have gained popularity as a tool to investigate the neural substrates of behaviour in rodents. When used with spontaneous behavioural tests of memory in rodents, DREADDs allow for a unique opportunity to advance our understanding …

  10. Behavioural, Pharmacological, and Immunohistochemical Investigation of 50 kHz USVs as an Expression of Positive Emotional Arousal in the Long Evans Rat

    Mulvihill, KevinBrock University2019

    The emission of ultrasonic vocalizations (USVs) in Rattus norvegicus is thought to effectively represent an underlying emotional state within the organism manifested at the behavioural level. The main goal of my thesis was to characterize, at multiple levels of analysis, the 50 kHz USVs of the …
