The Effects Of Adolescent Chronic Mild Stress: In Female Wistar-Kyoto Rats, Anna Hallowell
The Journal of Purdue Undergraduate Research
Despite years of research to understand under-lying mechanisms and develop more effective treatment approaches for mood disorders, numerous challenges exist. Many chronic stress models are used to study mood disorders, how-ever the majority have been established with adult males. This is problematic considering that affective disorders are more common in women, and generally develop during late adolescence. Studies have indicated fundamental behavioral, physiological, and neural differences between males and females in response to the same external stressors, furthering a need to develop sex-specific paradigms to accurately model the etiology of mood disorders in females. The Wistar-Kyoto (WKY) rat strain is …

Animal Sentience
In certain situations, insects appear to lack a response to noxious stimuli that would cause pain in humans. For example, from the fact that male mantids continue to mate while being eaten by their partner it does not follow that insects do not feel pain; it could be the result of modulation of nociceptive inputs or behavioural outputs. When we try to infer the underlying mental state of an insect from its behaviour, it is important to consider the behavioural effects of the associated physiological and neurobiological mechanisms.

Animal Sentience
I briefly recap the messages of the target article by Wiebers & Feigin (2020) and the accompanying peer commentaries about what we learn from the COVID-19 pandemic. Using the rapid evolution of viruses as an example of the importance of prevention, I explore why it is difficult for our species to foresee and prevent unintended global changes resulting from human activity. I end with a discussion about the long-term future, the ultimate problem inherent in our current mindset and the structure of our economy: growth.

Animal Sentience
Mikhalevich & Powell provide convincing empirical evidence that at least some invertebrates are sentient and hence should be granted moral status. I agree and argue that functional markers should be the primary indicators of sentience. Neuroanatomical homologies provide only secondary evidence. Consensus regarding the validity of these functional markers will be difficult to achieve. To be effective in practice, functional markers of sentience will have to be tested and accepted species by species to overcome the implicit biases against extending moral status to invertebrates.
