“…Even before this study, it has been well established that the clock neurons form a vastly overlapping network (Helfrich‐Förster, ; Helfrich‐Förster et al, ), which integrates multisensory inputs (e.g., light and temperature cues) from the environment (Helfrich‐Förster et al, ; Yoshii, Sakamoto, & Tomioka, ; Yoshii et al, ; Busza, Murad, & Emery, ; Yoshii et al, ; Veleri, Rieger, Helfrich‐Förster, & Stanewsky, ; Picot, Klarsfeld, Chélot, Malpel, & Rouyer, ; Sehadova et al, ; Yoshii, Vanin, Costa, & Helfrich‐Förster, ; Kaneko et al, ; Buhl et al, ; Harper, Dayan, Albert, & Stanewsky, ; Tang et al, ). Although Drosophila 's clock has been shown to have an implication on the fly's metabolism (Xu, Zheng, & Sehgal, ; Xu, DiAngelo, Hughes, Hogenesch, & Sehgal, ), sleep (Hendricks et al, ; Shaw, Cirelli, Greenspan, & Tononi, ; Hendricks et al, ), the control of locomotor rhythms (Konopka & Benzer, ; Handler & Konopka, ; Helfrich & Engelmann, ), the gating of eclosion and metamorphosis (Pittendrigh & Skopik, ; Konopka & Benzer, ; Hamblen‐Coyle, Wheeler, Rutila, Rosbash, & Hall, ; Sehgal, Price, Man, & Young, ; Myers, Yu, & Sehgal, ), as well as on learning and memory (Lyons & Roman, ; Fropf et al, ; Chouhan, Wolf, Helfrich‐Förster, & Heisenberg, ), the coverage of specific connections to downstream neurons of the circadian network still lags behind.…”
