The Cell Birth Marker BrdU Does Not Affect Recruitment of Subsequent Cell Divisions in the Adult Avian Brain

Figure 4

Three confocal images of the same brain tissue demonstrating double-labeling of Hu (brown) and BrdU (fluorescence). Two (red nuclei) of the several neurons (Hu⁺, brown) shown in this field were born at the time of BrdU injections. (a) BrdU labeling. (b) Hu labeling. (c) Colocalization of BrdU and Hu labeling.
