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 the area of healed/healing infarction (I) and more normal brain parenchyma (B). In the infarcted area contains numerous microglia (brain macrophages) that have phagocytosed dead brain cell debris that are called "gitter cells". In the more normal brain tissue there 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 infarcted the brain tissue with adjacent to the infarct. In this image there are numerous macrophages (microglia) enlarged activated astrocytes that are full often seen in areas of brain tissue healing - gitter cells gemistocytic astrocytes (arrows).File:IPLab3BrainInfarction7b.JPG|This is a higher-power photomicrograph of the infarcted brain tissue adjacent to the infarct. There are with numerous enlarged activated astrocytes macrophages (microglia) that are often seen in areas full of healing brain tissue - gemistocytic astrocytes gitter cells (arrows).
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.
