Cytochemical study of the "amoeboid cells" in the corpus callosum in the early postnatal rat brain showed that a few of them exhibited peroxidase activity. The enzyme activity was localized in a variable number of cytoplasmic granules measuring 0.2 micron and this resembles that of monocyte-derived macrophages.
