Here, we present a protocol to quantify nest building behavior in mice, which is known to be impaired in several neurological disorders and diseases. This protocol examines the utility of four materials and offers the opportunity to quantify the rater agreement in scoring, improving the validity and reliability of the assay.

Certain organic substances change color in dilute solution when the hydronium ion concentration reaches a particular value. For example, phenolphthalein is a colorless substance in any aqueous solution with a hydronium ion concentration greater than 5.0 × 10−9 M (pH < 8.3). In more basic solutions where the hydronium ion concentration is less than 5.0 × 10−9 M (pH > 8.3), it is red or pink. Substances such as phenolphthalein, which can be used to determine the pH of a solution, are called...

The experimental protocol demonstrates the paradigm for acquiring and analyzing electroencephalography (EEG) signals during upper limb movement in individuals with stroke. The alteration of the functional network of low-beta EEG frequency bands was observed during the movement of the impaired upper limb and was associated with the degree of motor impairment.

A system for acquiring data from self-initiated individual behavior sessions within a social colony cage setting is presented. The efficacy of this system is demonstrated using an automated skilled reach assessment, enabling the characterization of post-stroke motor impairments, potential behavioral alterations related to motivation, circadian variations, and other innovative dependent variables.

Mouse models have become increasingly popular in studies of behavioral neuroscience. As models advance, it is important to develop sensitive behavioral measures specific to the mouse. This protocol describes the Pasta Matrix Reaching Task, which is a skilled motor task for use in mouse models of stroke.
FAQs
Stroke-related injury can interrupt neural circuits that support cognition rather than only circuits controlling movement. Confusion and impaired judgment may therefore reflect disrupted brain function even when weakness is not prominent. This matters because observers who focus only on motor signs may overlook a sudden neurological change and delay emergency evaluation.
Difficulty speaking or understanding language provides evidence that stroke has affected neural systems supporting communication. These changes are behaviorally observable and can help clinicians connect a person’s symptoms with disrupted brain function during neurological assessment. Recognizing them is especially important when communication problems are more noticeable than other physical warning signs.
Spatial neglect shows that stroke can disturb how the brain processes or attends to part of the surrounding space. A person may exhibit an unusual behavioral response even without an obvious motor deficit. Identifying this pattern helps clinicians relate behavior to affected brain regions and networks, supporting assessment and rehabilitation planning.
Sudden changes in emotion, judgment, or goal-directed behavior can signal disruption of brain circuits involved in organizing purposeful actions and regulating responses. These findings broaden recognition beyond speech and movement problems. Their sudden appearance provides clinically relevant behavioral information that can be considered alongside other warning signs during urgent evaluation.
Caregivers and clinicians should treat a sudden behavioral change as important neurological information rather than dismissing it as ordinary confusion or unusual conduct. They can consider cognition, communication, emotion, judgment, and spatial behavior together with physical warning signs. This combined recognition supports rapid neurological assessment and emergency treatment.
Behavioral observations help connect a person’s symptoms with affected brain regions and broader neural networks. Clinicians can use that relationship during neurological assessment to characterize the disruption more fully, including changes that are not captured by obvious weakness. The resulting information can also guide rehabilitation planning around cognition, communication, behavior, or spatial difficulties.
