Figure 6. Larval sleep deprivation attenuates proliferation of neural progenitor cells.

Image of second instar larval brain and ventral nerve cord (dashed outline) labeled with anti-PH3 (dividing cells) following normal sleep (A) or 3 hr of sleep deprivation (B). (C) Quantification of dividing cells in controls, after sleep deprivation, and following recovery sleep (n = 35, 42, 24 larvae per condition). (D,E) Schematic of closed-loop sleep deprivation system (D) and control (E). (F) Total sleep per hour in larvae exposed to light stimulus in a closed-loop system during only wake (control, n = 28) or only sleep (deprived, n = 16). (G) Quantification of dividing cells in controls (n = 9) or after sleep deprivation (n = 10) using a closed-loop system. Scale bar = 40 µm.

Figure 6—figure supplement 1.

Quantification of total neuroblast (NB) number in control (n = 13) or sleep-deprived (n = 15) larvae demonstrates that the total pool of NBs (dividing and non-dividing) is not changed following sleep deprivation. p=0.872.
