TLDR
Together these agents appear to determine the complex physiologic responses to a variety of stressors.Abstract:
Stress stimulates several adaptive hormonal responses. Prominent among these responses are the secretion of catecholamines from the adrenal medulla, corticosteroids from the adrenal cortex, and adrenocorticotropin from the anterior pituitary. A number of complex interactions are involved in the regulation of these hormones. Glucocorticoids regulate catecholamine biosynthesis in the adrenal medulla and catecholamines stimulate adrenocorticotropin release from the anterior pituitary. In addition, other hormones, including corticotropin-releasing factor, vasoactive intestinal peptide, and arginine vasopressin stimulate while the corticosteroids and somatostatin inhibit adrenocorticotropin secretion. Together these agents appear to determine the complex physiologic responses to a variety of stressors.read more

From Neurons to Neighborhoods: The Science of Early Childhood Development
TL;DR: From Neurons to Neighborhoods as discussed by the authors presents the evidence about "brain wiring" and how children learn to learn to speak, think, and regulate their behavior, and examines the effect of the climate-family, child care, community-within which the child grows.

Physiological changes in fish from stress in aquaculture with emphasis on the response and effects of corticosteroids
Bruce A. Barton,George K. Iwama +1 more
TL;DR: Stress, through the action of corticosteroids, may reduce immunocompetence by influencing lymphocyte numbers and antibody-production capacity, and affect reproduction by altering levels and patterns of reproductive hormones that influence maturation.

Oxytocin and vasopressin in the human brain: social neuropeptides for translational medicine
TL;DR: OXT and AVP are emerging as targets for novel treatment approaches — particularly in synergistic combination with psychotherapy — for mental disorders characterized by social dysfunction, such as autism, social anxiety disorder, borderline personality disorder and schizophrenia.

Physiological and behavioral responses to corticotropin-releasing factor administration: is CRF a mediator of anxiety or stress responses?
Adrian J. Dunn,Craig W. Berridge +1 more
TL;DR: The cerebral distribution of CRF and binding sites for CRF is described in detail in the second part of this report, which aims to establish a baseline for the distribution of these sites in the brain.

TL;DR: Field work reveals that changes in responsiveness to LPFs have ecological bases, such as reproductive state, body condition etc., that in turn indicate different hormonal control mechanisms in the HPA cascade.

Additive effects of epinephrine and corticotropin-releasing factor (CRF) on adrenocorticotropin release in rat anterior pituitary cells.
Vincent Giguère,Fernand Labrie +1 more
TL;DR: The present data show that the additive effect of epinephrine on CRF-induced ACTH release is achieved through an alpha-adrenergic receptor and is accompanied by a marked stimulation of intracellular cyclic AMP levels.

Adrenaline, noradrenaline and dopamine levels in specific brain stem areas of acutely immobilized rats.
TL;DR: The results implicate the participation of central adrenaline neurons, localized in specific brain stem areas, and noradrenaline neurons innervating the rostral part of the nucleus tractus solitarii, in the mechanism of central response to acute stress.

Influence of the frequency of ovine corticotropin-releasing factor administration on adrenocorticotropin and corticosterone secretion in the rat.
Catherine Rivier,Wylie Vale +1 more
TL;DR: It is concluded that CRF administered in a repeated or continuous manner to intact rats, while causing some pituitary desensitization, still elicits a significant degree of ACTH secretion despite the presence of elevated corticosterone release.

Effects of steroid hormones on the level of corticotropin messenger RNA activity in cultured mouse-pituitary-tumor cells.
TL;DR: Results indicate that at least part of the glucocorticoid action is exerted directly on the pituitary to suppress corticotropin messenger RNA activity.
