All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Rabbits possess powerful hindlimb musculature and are susceptible to spinal injury if they struggle or kick while inadequately supported. Because rabbits vary in temperament and may struggle during restraint, handlers should...

FAQs
Tracking the hypothalamic-pituitary-adrenal axis connects restraint exposure with downstream endocrine changes. Restraint activates corticotropin-releasing hormone and adrenocorticotropic hormone signaling, which promotes glucocorticoid release such as corticosterone in rodents. Following this sequence gives researchers a physiological readout for examining how sustained stress affects neuroendocrine regulation.
Neural plasticity provides a framework for asking whether sustained stress changes how the nervous system adapts over time. In this model, investigators can relate prolonged stress exposure to alterations in plasticity alongside anxiety-like behavior and cognition. That combination helps distinguish broader nervous-system effects from findings based only on endocrine measurements.
Repeated or prolonged exposure allows researchers to examine both stress adaptation and vulnerability. By comparing physiological regulation with anxiety-like behavior, cognition, and neural plasticity, the model can show whether responses remain adaptive or become associated with greater susceptibility to stress-related disorders. This connects laboratory stress responses with broader neuroscience questions.
An investigation generally starts with repeated or prolonged physical restriction and then assesses its consequences across endocrine, neural, and behavioral domains. The relevant sequence is exposure followed by evaluation of hypothalamic-pituitary-adrenal signaling, glucocorticoid release, neural plasticity, anxiety-like behavior, or cognition. Selecting several outcomes captures stress effects beyond one measurement.
Researchers can assess endocrine regulation through corticotropin-releasing hormone and adrenocorticotropic hormone signaling, with corticosterone release serving as a glucocorticoid outcome in rodents. They can also examine neural plasticity, anxiety-like behavior, and cognition. Together, these readouts indicate how sustained stress influences physiology, nervous-system function, and behavior.
It is used to investigate how prolonged stress influences the nervous system and to evaluate potential therapeutic interventions. Because the model links neuroendocrine signaling with plasticity, cognition, and anxiety-like behavior, it supports studies of stress adaptation and vulnerability. Results may help clarify mechanisms relevant to stress-related disorders without reducing them to endocrine changes alone.
