Social isolation reduces and fragments sleep. (a) Representative graph for the wCS10 strain showing reduced sleep over 24 hours in flies that were socially isolated (SI) (n = 112) versus the grouped/socially enriched (SE) flies (n=112). Total sleep is significantly reduced during the day and night in both (b) wCS10 and (c) w118ex (n = 56) in the SI compared to the SE conditions. (d) Sleep bout numbers are significantly reduced during the day and increased at night in SI wCS10. (e) SI significantly increases sleep bout numbers during the night in w1118ex flies. (f) Sleep bout duration is significantly decreased during the night in the SI wCS10 flies compared to the SE flies. (g) Sleep bout duration is decreased during both the day and the night in w1118ex flies SI flies. Socially isolated (SI) = kept as single female; socially enriched (SE) = kept with 30 females; Daytime = total sleep during lights on; Nighttime = total sleep during lights off; mean ± SEM shown, *p < .05, **p < .01, ***p < 0.001.
