Reconfiguration of a Multi-oscillator Network by Light in the Drosophila Circadian Clock (Current Biology)

Chatterjee et al. show that light modifies inter-oscillator coupling and clock-independent output gating in the Drosophila brain clock network. This dynamic flexibility in the interactions among the different oscillator nodes, in part defined by the neuropeptide PDF, allows the hardwired clock network to balance robustness with adaptability.
