Salivary cortisol as a biomarker in stress research.
TLDR
The present paper addresses several psychological and biological variables, which may account for such dissociations, and aims to help researchers to rate the validity and psychobiological significance of salivary cortisol as an HPAA biomarker of stress in their experiments.About:

Mental stress assessment using simultaneous measurement of EEG and fNIRS
Fares Al-Shargie,Masashi Kiguchi,Nasreen Badruddin,Sarat C. Dass,Ahmad Fadzil Mohammad Hani,Tong Boon Tang +5 more
TL;DR: This study suggests that combination of EEG (frontal alpha rhythm) and fNIRS (concentration change of oxygenated hemoglobin) could be a potential means to assess mental stress objectively.
Journal ArticleDOI
Cognitive Enhancement or Cognitive Cost: Trait-Specific Outcomes of Brain Stimulation in the Case of Mathematics Anxiety
TL;DR: It is shown that identical transcranial direct current stimulation (tDCS) exerts opposite behavioral and physiological effects depending on individual trait levels, which have implications for brain stimulation research by highlighting the role of individual traits in experimental findings.
Journal ArticleDOI
Sex differences in salivary cortisol reactivity to the Trier Social Stress Test (TSST): A meta-analysis
TL;DR: There are observed sex differences at various time points of the reactive cortisol following the TSST, and current results suggest that these sex differences can be, at least in part, attributed to variations in methodological considerations across studies.
Journal ArticleDOI
Utility of Salivary Cortisol Measurements in Cushing’s Syndrome and Adrenal Insufficiency
TL;DR: The measurement of cortisol in saliva is a simple, reproducible, and reliable test to evaluate the normal and disordered control of the hypothalamic-pituitary-adrenal (HPA) axis.

Effects of Chronic Stress on Memory Decline in Cognitively Normal and Mildly Impaired Older Adults
Guerry M. Peavy,David P. Salmon,Mark W. Jacobson,Aaron Hervey,Anthony Gamst,Tanya Wolfson,Thomas L. Patterson,Sherry Goldman,Paul J. Mills,Srikrishna Khandrika,Douglas Galasko +10 more
TL;DR: Chronic stress affects cognitive functioning differently in cognitively normal subjects and those with mild cognitive impairment, and Cortisol, while likely to have neurotoxic effects over time, may enhance cognitive functioning in older adults compromised by existing cognitive deficits.

Impact of gender, menstrual cycle phase, and oral contraceptives on the activity of the hypothalamus-pituitary-adrenal axis.
TL;DR: Although men seem to have a stronger hypothalamic drive in response to stressful stimulation than women, differences in salivary-free cortisol levels, at least in part, may be explained by estradiol-induced changes in corticosteroid-binding protein levels.

Free Cortisol Levels after Awakening: A Reliable Biological Marker for the Assessment of Adrenocortical Activity
Jens C. Pruessner,Oliver T. Wolf,Dirk H. Hellhammer,Angelika Buske-Kirschbaum,K. von Auer,Silke Jobst,F. Kaspers,Clemens Kirschbaum +7 more
TL;DR: Early morning cortisol levels can be a reliable biological marker for the individual's adrenocortical activity when measured repeatedly with strict reference to the time of awakening, in contrast to single assessments at fixed times.

Maternal care during infancy regulates the development of neural systems mediating the expression of fearfulness in the rat
Christian Caldji,Beth Tannenbaum,Shakti Sharma,Darlene D. Francis,Paul M. Plotsky,Michael J. Meaney +5 more
TL;DR: It is suggested that maternal care during infancy serves to "program" behavioral responses to stress in the offspring by altering the development of the neural systems that mediate fearfulness.
Journal ArticleDOI
Limbic system mechanisms of stress regulation: hypothalamo-pituitary-adrenocortical axis.
TL;DR: The influence of the limbic system on the HPA axis is likely the end result of the overall patterning of responses to given stimuli and glucocorticoids, with the magnitude of the secretory response determined with respect to the relative contributions of the various structures.

The cortisol awakening response (CAR): Facts and future directions
TL;DR: It is hypothesized that the anticipation of the upcoming day is of major relevance for the magnitude of the cortisol awakening response, and considerations are addressed concerning the exact function of the CAR.
