Sentences with phrase «hpa activation»

Similarly, Francis et al54 have shown that environmental enrichment can reverse the effects of early stress on HPA activation and behavioral response to stress.

Because both background environmental stressors as part of the daily routine in the animal facility and social stressors afforded by the rats» social environment may have provided necessary HPA activation for maternal behavior to exert a modulatory influence, such a correlation is at best consistent with a possible role of maternal care, but it can not be taken as conclusive evidence for sufficiency.

Although stress is generally viewed as having a negative influence on cognitive function, several recent studies demonstrate that HPA activation can facilitate learning under conditions of arousal (19).

One mechanism is activation of the hypothalamic — pituitary — adrenal axis (HPA) axis, which is a complex set of interactions between three glands: the hypothalamus, pituitary gland, and adrenal glands.

Animal studies have shown that maternal HPA axis activation not only affects the maternal immune system but also the offspring's immune system [20,25,26].

Thus, the physiological mechanisms underlying the associations found in the present study may be linked to maternal HPA axis activation.
