Anthropomorphic Denial Of Fish Pain, Lynne U. Sneddon, Matthew C. Leach Sep 2019

Anthropomorphic Denial Of Fish Pain, Lynne U. Sneddon, Matthew C. Leach

Lynne Sneddon, PhD

Key (2016) affirms that we do not know how the fish brain processes pain but denies — because fish lack a human-like cortex — that fish can feel pain. He affirms that birds, like fish, have a singly-laminated cortex and that the structure of the bird brain is quite different from that of the human brain, yet he does not deny that birds can feel pain. In this commentary we describe how Key cites studies that substantiate mammalian pain but discounts the same kind of data as evidence of fish pain. We suggest that Key's interpretations are illogical, do not …


Relationship Of Maternal And Infant Cortisol Matrices With Later Infant Behavior And Temperament, Anastasia Perris Jun 2019

Relationship Of Maternal And Infant Cortisol Matrices With Later Infant Behavior And Temperament, Anastasia Perris

Anastasia Perris

 Prenatal stress has been correlated with adverse developmental outcomes affecting infant cognition and behavior. Previous studies have shown that prenatal stress can lead to increased susceptibility to adult disease but few studies have looked at the physiological stress response system by measuring the activity of the hypothalamic-pituitary-adrenal (HPA) axis. Cortisol, the output of the HPA axis can be secreted in many different matrices (saliva, blood, urine, feces and hair). Most studies that do, only look at one measure of hormone production instead of examining multiple matrices. Additionally these studies do not look at the relationship between matrices. Hair provides a …
