The stress response is conserved throughout evolution, and a similar response can be measured across taxa. This similarity across species has enabled the development of a variety of different animal models (monkeys, apes, chinchillas, mice, rats, fruit-flies, zebrafish) to examine stress-related effects through laboratory interventions and field studies.
Abstract. Stress is a potent modulator of learning and memory processes. Although there have been a few attempts in the literature to explain the diversity of effects (including facilitating, impairing, and lack of effects) described for the impact of stress on memory function according to single classification criterion, they have proved insufficient to explain the whole complexity of effects.
May 4, 2022 · Figure 4. Memory changes under stress. Acute stress induces time-dependent changes in memory, enhancing some processes (green) while impairing others (red). These time-dependent changes in memory are thought to be directly linked to the temporal profiles of action of major stress mediators (see Figure 1).
Abstract. Stress is recognized as an important issue in basic and clinical neuroscience research, based upon the founding historical studies by Walter Canon and Hans Selye in the past century, when the concept of stress emerged in a biological and adaptive perspective. A lot of research after that period has expanded the knowledge in the stress ...
May 7, 2024 · Any physical or psychological stimuli that disrupt homeostasis result in a stress response. The stimuli are called stressors, and physiological and behavioral changes in response to exposure to stressors constitute the stress response. A stress response is mediated through a complex interplay of nervous, endocrine, and immune mechanisms, activating the sympathetic-adreno-medullar (SAM) axis ...

This time-dependent effect of stress on memory encoding, according to the dual-mode model, is thought to be mediated by the different time courses of distinct stress-responsive hormones: Norepinephrine increases and decreases relatively quickly in the stress response and is thought to mediate some of the rapid effects of stress on memory, whereas cortisol increases and decreases at a slower ...
