The framework of allostasis, allostatic load and overload (i.e., stability through change) attempts to combine homeostasis processes in day-to-day responses physiology behavior. These include predictive changes environment such as seasons, facultative perturbations. latter can be severe, occur at any time, may present considerable additional challenges homeostasis. Hormonal cascades, the hypoth...

Abstract This paper integrates emerging evidence from two broad streams of scientific literature into one common framework: (a) hierarchical gradients functional connectivity that reflect the brain’s large-scale structural architecture (e.g., a lamination gradient in cerebral cortex); and (b) approaches to predictive processing its specific instantiations called allostasis (i.e., regulation ene...

This paper outlines a hierarchical Bayesian framework for interoception, homeostatic/allostatic control, and meta-cognition that connects fatigue and depression to the experience of chronic dyshomeostasis. Specifically, viewing interoception as the inversion of a generative model of viscerosensory inputs allows for a formal definition of dyshomeostasis (as chronically enhanced surprise about bo...

Glycemic allostasis is the process by which blood glucose stabilization is achieved through the balancing of glucose consumption rate and release into the blood stream under a variety of stressors. This paper reviews findings on the dynamics of glycemic levels during mental activities on fasting in non-alcohol users and alcohol users with different periods of abstinence. Referred articles for t...

Increases in sedentary lifestyle and high calorie food consumption, among other factors, have contributed to epidemic levels of childhood obesity in the United States.1 Children who are overweight during the preschool period are more likely to become overweight adolescents and obese adults.2 In fact, a rapid gain in body mass index (BMI) in early childhood has been shown to affect adulthood mor...

This paper is a review of the effects of stress on reproduction in fishes. I hope to further the development of the concepts of allostasis and hormesis as relevant to understanding reproduction in general and in fish in particular. The main contentions I derive in this review are the following: Stressors affect fish reproduction in a variety of ways depending on the nature and severity of the s...
