Predator-induced changes in metabolism cannot explain the growth/predation risk tradeoff. [PDF]
PLoS ONE, 2009 Defence against predators is usually accompanied by declining rates of growth or development. The classical growth/predation risk tradeoff assumes reduced activity as the cause of these declines.

Individual strategies of aggressive and non-aggressive male mice in encounters with trained aggressive residents [PDF]
, 1992 To determine whether individual differences in offensive behaviour are related to differences in defensive behaviour, the responses of male wild house mice, Mus domesticus, of an aggressive and a non-aggressive line to defeat by physically stronger ...

Aversive emotion rapidly activates orexin neurons and increases heart rate in freely moving mice
Molecular Brain, 2021 The perifornical area of the hypothalamus has been known as the center for the defense response, or fight-or-flight response, which is characterized by a concomitant rise in arterial blood pressure, heart rate, and respiratory frequency.

A-Kinase Anchoring Proteins in Cardiac Myocytes and Their Roles in Regulating Calcium Cycling
Cells, 2023 The rate of calcium cycling and calcium transient amplitude are critical determinants for the efficient contraction and relaxation of the heart. Calcium-handling proteins in the cardiac myocyte are altered in heart failure, and restoring the proper ...

Behavioural inhibition and valuation of gain/loss are neurally distinct from approach/withdrawal [PDF]
, 2019 Gain or omission/termination of loss produces approach; while loss or omission/termination of gain produces withdrawal. Control of approach/withdrawal motivation is distinct from valuation of gain/loss and does not entail learning – making “reward” and ...
