Subjective well-being (SWB) refers to an individual's self-evaluation of their overall life satisfaction, happiness, and fulfillment. This multifaceted construct is typically assessed by analyzing the balance of positive and negative emotions alongside perceptions of life satisfaction. Personality traits such as neuroticism and extraversion are strongly associated with variations in SWB, offering critical insights into the underlying mechanisms of emotional well-being. Neuroticism and Emotional...

The primary outcome measure in clinical trials for neuromuscular disorders is generally improved muscle function. Therefore, assessing the effect of potential therapeutic compounds on muscle performance pre clinically in mouse models is of great importance. We here describe several functional tests to address this.

Assessment of Vascular Regeneration in the CNS Using the Mouse Retina

The rodent retina has long been recognized as an accessible window to the brain. In this technical paper we provide a protocol that employs the mouse model of oxygen-induced retinopathy to study the mechanisms that lead to failure of vascular regeneration within the central nervous system after ischemic injury. The described system can also be harnessed to explore strategies to promote regrowth of functional blood vessels within the retina and CNS.
FAQs
Different signs can change for different reasons, so activity, grooming, nesting, feeding, social interaction, and responses to handling should be considered together. Comparing several observations with expected patterns or an individual baseline provides stronger evidence of altered welfare than relying on one measure alone. This approach helps researchers recognize meaningful changes while reducing misinterpretation.
An individual baseline shows what is typical for a particular mouse before or during a study. Changes can then be judged against that mouse’s own pattern, rather than against a general expectation alone. This comparison is especially relevant when normal behavior varies among animals, and it can help distinguish meaningful welfare changes from ordinary behavioral differences.
A mouse’s response to handling is one part of the broader behavioral picture. When considered alongside activity, grooming, nesting, feeding, and social interaction, handling responses may help identify changes in comfort or distress. The value comes from comparison with expected behavior or an individual baseline, not from treating one response as a complete welfare judgment.
Stress or discomfort can alter behavior and introduce variability into experimental data. Assessing well-being therefore provides context for deciding whether an observed behavioral difference may reflect the research question, an altered welfare state, or both. Incorporating these observations can improve interpretation and support conclusions that account for conditions capable of influencing behavior.
A practical assessment can include activity, grooming, nesting, feeding, social interaction, and responses to handling. Researchers compare these observations with expected patterns or with each animal’s individual baseline, looking for meaningful changes rather than isolated abnormalities. Considering the set together supports recognition of comfort or distress and avoids overreliance on one behavioral signal.
Repeated or meaningful changes in observable behavior can provide information for welfare decisions, including the use of humane endpoints. The assessment does not depend on a single sign; instead, multiple observations and baseline comparisons help identify concerning changes. This supports timely decisions intended to limit distress while maintaining a structured approach to monitoring.
Patterns in activity, grooming, nesting, feeding, social interaction, or handling responses can reveal how housing or experimental procedures affect welfare. Researchers can use those observations to identify conditions that may need refinement. Improving the fit between the environment, procedures, and the animals’ behavioral state can also reduce welfare-related variability in behavioral data.
In behavior research, welfare observations provide essential context for experimental measurements. A change in behavior may be relevant to the study, but stress or discomfort can also influence the same outcomes. Monitoring well-being helps researchers interpret findings more carefully, recognize potential confounding effects, support humane endpoints, and evaluate whether housing or procedures require refinement.
