This video demonstrates the assessment of the infarct zone and brain edema in brain slices from rats subjected to middle cerebral artery occlusion. Infarcted areas are identified using redox staining, while a blue filter and threshold function in image analysis software quantify the infarct zone and edema in the affected hemisphere.

This manuscript describes a modeling technique of capsular infarct. Here we utilized a modified photothrombotic technique with low intensity of light after pre-surgery target mapping. Using this technique, we created a circumscribed capsular infarct model with persistent motor impairment.

The post-mortem assessment of myocardial infarction (MI) in rodents is based on quantification of the infarct on stained heart sections. We describe an accurate method to quantify the infarct size using systematic sampling of harvested rat hearts from base to apex and image analyses of trichrome-stained histological sections.
FAQs
After blood flow is interrupted, reduced oxygen and glucose limit cellular energy production. The resulting energy deficit disrupts ion balance, creating conditions associated with neuronal death and edema. Tracking these linked changes helps investigators interpret how ischemic injury develops and evaluate its biological consequences in brain tissue.
A defined infarct region separates visibly or structurally injured tissue from unaffected tissue, allowing researchers to characterize the extent of damage. Measuring this region provides a basis for comparing injury across experimental conditions and relating tissue loss to cellular changes, disease progression, or functional outcomes.
Brain imaging can reveal the distribution of injury within the brain, whereas tissue sectioning and histological staining provide detailed evidence from prepared tissue sections. Used together, these approaches connect the overall location of a lesion with cellular or structural features, strengthening interpretation of ischemic damage.
A typical workflow uses brain imaging or prepared tissue sections to identify damaged areas, applies histological staining when tissue-level evaluation is needed, and then measures the lesion or infarct volume. The resulting structural assessment can be compared with cellular findings and behavioral outcomes to support biological interpretation.
Lesion-volume measurement estimates the amount of brain tissue included in the infarct region. This quantitative outcome helps distinguish smaller from larger injuries and supports comparisons among disease stages or experimental conditions. Researchers can then examine whether structural damage corresponds with cellular consequences, behavioral changes, or treatment-related differences.
This analysis supports investigations of stroke mechanisms, disease progression, neuroprotective treatments, and functional recovery. Its value comes from linking structural damage with cellular and behavioral outcomes, enabling researchers to assess how injury changes over a study and whether an intervention is associated with reduced damage or improved recovery.
