Adapting To Uncertainty: Effects Of Environmental Instability On Zebrafish Behaviour, Britney Sekulovski
Adapting To Uncertainty: Effects Of Environmental Instability On Zebrafish Behaviour, Britney Sekulovski
Theses and Dissertations (Comprehensive)
This thesis addresses how animals cope with unpredictability by testing how environmental stability changes the behaviour of zebrafish (Danio rerio) in two complementary experiments. In Experiment 1, fish lived for three months in either a Dynamic environment (water temperature, feeding times, habitat complexity, group size, and membership fluctuated) or a Stable environment (all factors constant). Across seven behavioural assays, measuring individual behavioural differences, collective movement, social memory, and information use, Dynamic condition fish were found to be more sensitive to social cues and more likely to conform to recent social information, independent of the quality of the information …
The Effects Of Environmental Complexity On Brain Development And Personality Expression In Western Hognose Snakes, Gokulan Nagabaskaran
The Effects Of Environmental Complexity On Brain Development And Personality Expression In Western Hognose Snakes, Gokulan Nagabaskaran
Theses and Dissertations (Comprehensive)
There is growing interest in snake cognition, personality, and welfare as more snakes are kept as pets, yet little research has been conducted. The effects of enrichment and environmental factors have been well documented in other taxa, and recent evidence suggests that snakes may benefit in similar ways. This dissertation investigated the impact of environmental and social enrichment on personality expression, personality stability, and brain development. Western hognose snakes (Heterodon nasicus) were used as the model species, as they are a popular choice in the pet trade. This allows the research to be readily translatable to husbandry practices of many …
Vapourized Cannabis Extract Administration Impairs Memory And Alters Neural Activity In Laboratory Rats, Megan Chladny
Vapourized Cannabis Extract Administration Impairs Memory And Alters Neural Activity In Laboratory Rats, Megan Chladny
Theses and Dissertations (Comprehensive)
Although people have smoked cannabis for millennia, administration of cannabis by heating the dried plant material or distilled extracts to a temperature just below the combustion point (i.e., vapourization or "vaping") has rapidly increased over the past few years (Javadi-Payder, Cole, and Taffe, 2018; Manwell, Charchoglyan, Brewer, Matthews, Heipel, and Mallet, 2014). Conversely, most of the cannabinoid research using rodent models has used parenteral routes of administration to examine the effects of purified cannabis extracts such as ∆9-tetrahydrocannabinol (THC), making it difficult to directly compare laboratory research to human drug use. Building on previous studies showing that THC …
The Avian Hippocampal Declarative Memory System, Chelsey C. Damphousse
The Avian Hippocampal Declarative Memory System, Chelsey C. Damphousse
Theses and Dissertations (Comprehensive)
Across Mammalia, memory has long been dissociated into multiple component systems specialized to process specific facets of experience. Among these segregated systems, declarative memory is processed by the hippocampus and surrounding structures, which have collectively been referred to as the hippocampal declarative memory system (HDMS). The HDMS, in turn, can be further divided into parallel streams dedicated to the processing of spatial versus object identity based information, commonly discussed as the ‘what’ and ‘where’ streams. While we know that the organization of the HDMS is conserved in humans, nonhuman primates, and rats, evidence outside Mammalia is lacking. Here HDMS homology …
An Exploration Of The Wheel-Induced Feeding-Suppression, Stephen Benjamin Peckham
An Exploration Of The Wheel-Induced Feeding-Suppression, Stephen Benjamin Peckham
Theses and Dissertations (Comprehensive)
Anorexia nervosa is an enigmatic human condition typified by food-restriction that is often accompanied by extensive exercise. This has been modeled in rats in the wheel-induced feeding-suppression (WIFS) model. In this model, animals are given access to a running-wheel, which induces a volitional drop in food-consumption. Short periods of wheel access have induced a feeding-suppression which is effectively reversed by chlorpromazine administration (Adams et al., 2009). Recent attempts at replicating Adams et al.’s (2009) feeding-suppression have, however, been unsuccessful (Peckham et al., 2013). These attempts raised questions as to whether or not the existing methodology is most effective at suppressing …
A Bittersweet Investigation Of Availability And Nutritive Value As Determinants Of Volitional Sucrose Consumption, Milan D. Valyear
A Bittersweet Investigation Of Availability And Nutritive Value As Determinants Of Volitional Sucrose Consumption, Milan D. Valyear
Theses and Dissertations (Comprehensive)
Rats given ~24 h access to a 4% sucrose solution every 3rd day (E3DA) consume about 100 g more solution than rats with continuous, everyday access (EDA). Under the same EDA-E3DA conditions rats will consume similar amounts of a more concentrated 8 or 16% sucrose solutions (Eikelboom, Hewitt, & Adams, Unpublished). It maybe that with these more concentrated solutions rats hit a satiety limit that prevents a difference between EDA and E3DA consumption from being evident. Experiment 1 was conducted to investigate the effect of adding quinine to 4% and 8% sucrose solutions with the intention of reducing consumption …
Recovery From Acute Toluene Intoxication Is Facilitated By The Nmda Receptor Co-Agonist D-Serine, But Not The Gabaa Receptor Antagonist Picrotoxin, Susan R. Samuel-Herter
Recovery From Acute Toluene Intoxication Is Facilitated By The Nmda Receptor Co-Agonist D-Serine, But Not The Gabaa Receptor Antagonist Picrotoxin, Susan R. Samuel-Herter
Theses and Dissertations (Comprehensive)
Toluene is a volatile solvent found in many household products and when intentionally inhaled results in intoxication. In rats, acute inhalation of toluene results in sedation and neurological impairments, with marked increases in ambulation and vertical behaviour during the recovery period. Previous in vitro research has shown that toluene may exert its effects by inhibiting NMDA receptors, and / or by activating GABAA receptors. To test whether modulation of these receptors are also implicated in the changes in motor behaviour and neurological impairments resulting from toluene vapour inhalation, rats were injected with the NMDA receptor co-agonist D-serine (1000 mg/kg …
