File:IPLab3BrainInfarction3b.JPG|This is a low-power photomicrograph of this brain with several areas of infarcted tissue. Note the pale areas which correspond to areas with loss of brain parenchyma (arrows).
File:IPLab3BrainInfarction4b.JPG|This photomicrograph shows the area of healed/healing infarction (I) and more normal brain parenchyma (B).
File:IPLab3BrainInfarction5b.JPG|This is a higher-power photomicrograph of the previous image showing that the inflammatory cells area of healed/healing infarction (arrowsI) are primarily macrophages and more normal brain parenchyma (B). In the infarcted area contains numerous microglia which (brain macrophages) that have phagocytosed dead brain cell debris that are called "gitter cells". In the dead more normal brain tissuethere are several enlarged astrocytes. These activated astrocytes are often seen in areas of healing and they are called "gemistocytic astrocytes".File:IPLab3BrainInfarction6b.JPG|This is a higher-power photomicrograph of the brain tissue adjacent to the area of infarctioninfarct. There In this image there are numerous enlarged activated astrocytes that are often seen in areas of brain healing - gemistocytic astrocytes (arrows).File:IPLab3BrainInfarction7b.JPG|This is a higher-power photomicrograph of the edge of the infarct. The infarcted brain tissue with numerous macrophages (microglia) that are full of brain tissue (“gitter cells”) are at the top of the image - gitter cells (arrows) and the brain parenchyma containing gemistocytic astrocytes is at the bottom.
File:IPLab3BrainInfarction10.jpg|This is a gross photograph of a brain from another patient with an old healed infarct. Note the meninges overlying the infarcted region (arrow).
File:IPLab3BrainInfarction11.jpg|This is a closer view of the brain demonstrating an old healed infarct with the meninges containing blood vessels (arrow) overlying the infarcted region.
