Disease, head injury, genetic modifications, and treatment of mice with drugs can have profound effects on behavior. Utilizing well-characterized and validated approaches such as marble burying and nestlet shredding, compulsive-like behaviors can be documented accurately in mice as models of human obsessive-compulsive disorder and autism spectrum disorder.

The ability to assess executive functions such as behavioral flexibility in rats is useful for investigating the neurobiology of cognition in both intact animals and disease models. Here we describe automated tasks for assessing strategy shifting and reversal learning, which are particularly sensitive to disruptions in prefrontal cortical networks.

Behavioral testing is the gold standard for determining outcomes following brain injury, and can identify the presence of developmental disabilities in infants and children. Neurodevelopmental reflexes are an early indicator of these abnormalities. A host of easily accomplished developmental reflex tests in the neonatal rodent were developed and described here.

The goal of the behavioral tests presented here is to detect functional deficits in rats after traumatic brain injury. Four specific tests are presented that detect deficits in behaviors to reflect the damage to specific brain areas at times extending to one year after injury.
FAQs
Behavioral outcomes serve as indirect measures of brain function. Changes in locomotion, exploration, task performance, or avoidance can indicate altered activity in neural circuits involved in movement, learning, memory, emotion, or sensory processing. Because a single behavior may reflect several processes, interpretation is strongest when researchers relate the result to the experimental manipulation and compare it with an appropriate control group.
Standardized environments reduce variation caused by factors unrelated to the research question. Consistent testing conditions, controlled stimuli or challenges, and objective scoring make differences between groups easier to attribute to brain injury, genetic factors, pharmacological treatment, or another experimental change. This control improves reproducibility and helps distinguish genuine behavioral effects from measurement or environmental inconsistencies.
A group difference indicates that the experimental alteration is associated with a changed behavioral response, but it does not by itself identify the underlying neural mechanism. Researchers must consider which outcome changed, whether the task specifically challenges the intended function, and whether other behavioral effects could influence performance. These comparisons support links between behavioral phenotypes and altered neural systems.
A typical workflow establishes comparable groups, places rats in a standardized task or environment, presents a controlled stimulus or challenge, and records predefined behavioral outcomes. Researchers then score or quantify the responses using consistent criteria and compare results across groups. Careful planning of conditions and scoring is essential because procedural variation can affect both observed behavior and reproducibility.
The outcome should match the function under investigation. Locomotion and exploration can inform studies of movement or general activity, whereas task performance may address learning and memory. Avoidance can provide information about emotional responses, and reactions to controlled stimuli can examine sensory function. Selecting outcomes that align with the neural question makes behavioral findings more interpretable.
In neuroscience, these assays help evaluate behavioral consequences of brain injury, genetic factors, and pharmacological treatments. They can also support disease modeling by showing how an experimental condition changes movement, cognition-related performance, emotion-related responses, or sensory behavior. When a treatment alters the measured outcome toward the comparison group's pattern, the result can inform evaluation of its potential therapeutic value.
