The Effects Of Visual Cue Facilitation In Spatial Pattern Learning In Rats, Sachia M. Grogan
The Effects Of Visual Cue Facilitation In Spatial Pattern Learning In Rats, Sachia M. Grogan
Undergraduate Honours Theses
Recently published research has shown that a consistent but not coincident visual pattern facilitated the learning of a diamond spatial pattern in humans (Katz, Brown & Sturz, 2014). The purpose of the present experiment was to examine if this could be done in rats, using a square spatial pattern. For each trial, 16 towers were arranged in a 4 X 4 matrix, with one of the nine possible 2 X 2 baiting patterns baited with cheese. The visual pattern group also had four striped towers placed in a 2 X 2 spatial pattern within the larger matrix, while the visual …

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 …
