File:IPLab3BrainInfarction3b.JPG|This is a low-power photomicrograph of this brain at the edge with several areas of the infarctinfarcted tissue. Note the pale areas which correspond to areas with loss of brain parenchyma (arrows).File:IPLab3BrainInfarction4b.JPG|This is a photomicrograph of shows the edge area of the infarct. Note the numerous inflammatory cells in the healed/healing infarction (I) and more normal brain parenchyma and adjacent to the remaining brain tissue (arrowsB).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 (arrows) and the brain parenchyma containing gemistocytic astrocytes is at the bottom.File:IPLab3BrainInfarction8.jpg|This is a high-power photomicrograph of gitter cells (arrows).File:IPLab3BrainInfarction9.jpg|This is a photomicrograph of the edge of the infarct. Note the gitter cells, gemistocytic astrocytes, and some hemosiderin-laden macrophages (arrows).
