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

Figure 7

Mean (±SE) percentages (%) of [³H]-thymidine⁺ neurons in NC, HVC, and HC, in the three experimental groups (control; 1 M: one month after BrdU treatment; 3 M: three months after BrdU treatment). In all the three investigated brain regions, no significant differences were found between experimental groups. Sample sizes: control and 1 M = 7 brains; 3 M = 6 brains.
