Fig. 6. Competence of glial division during adult life. (A) Time course of the percentage of antennal nerves with BrdU-positive cells after a 10-day-long feeding of BrdU until 50 days after adult eclosion. (B) Time course of the percentage of antennal nerves with BrdU-positive cells after antennal ablation. Antennae were ablated at the beginning of each period shown on the x-axis, and the flies were fed BrdU until the end of the period indicated. (C) Percentage of the brain with ectopic BrdU-positive cells around the site of injury. A needle was inserted on the day shown on the x-axis. The sample number (n) is indicated above each bar.
