Salivary Cortisol and Alpha-Amylase Connection in Mother-Infant Interactions

Ecologically salient stressors and supports and the coordination of cortisol and salivary alpha-amylase in mothers and infants. Author: Hibel LC, et al. (2018), Physiology and Behavior. ABSTRACT: This study examines the integration of the two main branches of the stress response system: the autonomic nervous system (via salivary alpha-amylase, sAA) and the hypothalamic-pituitary-adrenal axis (via cortisol). Mothers (n = 117) were […]

Nonhuman primates mirror human early life adversity & salivary cortisol/alpha-amylase responses

Effects of early life adversity on cortisol/salivary alpha-amylase symmetry in free-ranging juvenile rhesus macaques. Author: Petrullo LA, et al (2016), Horm Behav. Early life adversity (ELA) affects physiological and behavioral development. One key component is the relationship between the developing Hypothalamic-Pituitary-Adrenal (HPA) axis and the Sympathetic Nervous System (SNS). Recent studies suggest a relationship between […]
