Source: Yan, Z., et al. Evaluating the Anti-depression Effect of Xiaoyaosan on Chronically-stressed Mice. J. Vis. Exp. (2019).The video demonstrates the process of establishing a mouse model of chronic stress-induced depression and assessing depressive behaviors. The chronic application of various stressors triggers the release of corticosterone, leading to neuronal over-excitation and eventual neuronal death, which results in depression-like symptoms in the mice.

Source: Yong P. Chen, PhD, Department of Physics & Astronomy, College of Science, Purdue University, West Lafayette, IN This experiment will use inductive coils to demonstrate the concept of inductor and inductance. Magnetic induction will be demonstrated using a rod magnet inserted into or extracted away from the core of a coil to induce a transient electromotive force (emf) voltage in the coil, measured by a voltmeter. This experiment will also demonstrate the mutual inductance between...

Source: Ali Bazzi, Department of Electrical Engineering, University of Connecticut, Storrs, CT. Variable frequency drives (VFDs) are a type of adjustable speed drive, which are becoming standard equipment to power most AC induction motors. VFDs are common in industrial and automation applications and typically provide robust control of the motor in speed, torque, or position modes. The VFDs tested and simulated in this experiment focus on speed and open-loop control with constant voltage to...

University of Notre Dame, IN The Guide for the Care and Use of Laboratory Animals ("The Guide") states that pain assessment and alleviation are integral components of the veterinary care of laboratory animals. The definition of anesthesia is the loss of feeling or sensation. It is a dynamic event involving changes in anesthetic depth with respect to an animal's metabolism, surgical stimulation, or variations in the...

This article describes a protocol for inducing psychological stress in participants, which enables researchers to measure psychological, physiological and neuroendocrine responses to stress within single participants or between groups.
FAQs
Challenges used in stress induction can activate both the autonomic nervous system and the hypothalamic–pituitary–adrenal axis. Their coordinated activity changes arousal and hormone release, which may influence attention, coping behavior, and other measurable responses. Examining these linked systems helps researchers connect observed behavioral changes with the physiological processes that accompany stress.
Standardization makes the challenge, timing, and experimental conditions more consistent across participants or organisms. Appropriate controls provide a comparison for judging whether changes in attention, learning, memory, or social behavior are associated with the stressor rather than unrelated differences. Together, these features improve interpretation and make outcomes more suitable for comparison across studies.
Individuals may not respond to the same challenge in identical ways, producing differences in physiological activation, arousal, attention, or coping behavior. Stress induction allows these variations in stress reactivity to be measured under controlled conditions. Studying such differences can clarify why behavioral outcomes vary and can help researchers evaluate responses to potential interventions.
Stress-related changes in arousal and hormone release can be examined alongside performance in learning, memory, and attention tasks. This approach does not treat behavior as a single outcome; it allows researchers to determine which behavioral domains change after a challenge. Comparing stressed and control conditions can reveal patterns relevant to how stress influences cognition.
A useful procedure requires a clearly defined environmental, psychological, or physiological challenge, consistent implementation, and measurements that capture both behavioral and physiological responses. Researchers should also include appropriate controls and standardize relevant conditions. These safeguards support meaningful comparisons, help distinguish stress-related effects from procedural variation, and improve interpretation of the resulting data.
Researchers use stress induction to investigate how stress influences anxiety, learning, memory, social interactions, attention, and coping behavior. It can also support the study of individual differences in stress reactivity and the evaluation of interventions intended to reduce harmful effects. The method is therefore relevant wherever controlled stress responses must be related to behavioral outcomes.
Following a controlled challenge, researchers can assess changes in behavior together with physiological indicators linked to autonomic activity and the hypothalamic–pituitary–adrenal axis. Relevant behavioral outcomes include arousal, attention, coping, learning, memory, and social interaction. Measuring multiple outcomes provides a broader basis for interpreting how stress affects behavior and for comparing responses across conditions.
