Neuroscience Meets Salivary Bioscience: Interaction between sex, stress reactivity, and cingulum GFA
Sex-related differences in stress reactivity and cingulum white matter Wheelock, et al., ( 2021) Neuroscience ABSTRACT: The prefrontal cortex and limbic system are important components of the neural circuit that underlies stress and anxiety. These brain regions are connected by white matter tracts that support neural communication including the cingulum, uncinate fasciculus, and the fornix/stria-terminalis. […]

Salivary Bioscience Studies That Have Impact: Getting Back to Our ABCDs
(May 12, 2021) Since being funded in 2015, the Adolescent Brain and Cognitive Development (ABCD) Study has enrolled more than 10,000 children with the objective to study numerous facets of cognitive, social, emotional, and physical development over 10 years. This multi-site, nationwide epidemiologic study is the largest of its type and focus to date. Salimetrics’ [...]
Robust relationship between DHEA and emerging symptoms of pathological worry during adolescence
Increased dehydroepiandrosterone (DHEA) is associated with anxiety in adolescent girls Mulligan EM, et al., (2020) Psychneuroendocrinology ABSTRACT: The pubertal period is a time of rapid increase in the incidence of anxiety disorders, and thus, pubertal hormones may play a role in the precipitation of anxious psychopathology. DHEA, a steroid hormone that surges in adolescence, has […]
Impacting Associations Between Salivary Cortisol and Alpha-Amylase and Child Depressive Symptoms.
Child depressive symptoms: Associations with salivary cortisol and alpha amylase in two distinct challenges Khoury JE, et al., ( 2020) Biological psychology ABSTRACT: Child depression has been inconsistency linked to cortisol and salivary alpha-amylase (sAA) reactivity. This study assessed three factors that contribute to inconsistencies: 1) the differential effectiveness of laboratory challenges to elicit cortisol […]
