Waking experience modulates sleep need in mice
BMC Biology, 2021 Background Homeostatic regulation of sleep is reflected in the maintenance of a daily balance between sleep and wakefulness. Although numerous internal and external factors can influence sleep, it is unclear whether and to what extent the process that ...

Circadian desynchronization [PDF]
Interface Focus, 2010 The suprachiasmatic nucleus (SCN) coordinates via multiple outputs physiological and behavioural circadian rhythms. The SCN is composed of a heterogeneous network of coupled oscillators that entrain to the daily light–dark cycles. Outside the physiological entrainment range, rich locomotor patterns of desynchronized rhythms are observed.

Circadian Rhythm Abnormalities in Parkinson's Disease from Humans to Flies and Back [PDF]
, 2018 Clinical and research studies have suggested a link between Parkinson\u2019s disease (PD) and alterations in the circadian clock. Drosophila melanogaster may represent a useful model to study the relationship between the circadian clock and PD.

The Melanocortin-4 Receptor Integrates Circadian Light Cues and Metabolism [PDF]
, 2015 The melanocortin system directs diverse physiological functions from coat color to body weight homoeostasis. A commonality among melanocortin-mediated processes is that many animals modulate similar processes on a circannual basis in response to longer ...

The retinal ipRGC-preoptic circuit mediates the acute effect of light on sleep
Nature Communications, 2021 The preoptic area (POA) is critical for sleep regulation but its role in acute, non-circadian, light effects on sleep are unclear. The authors show that intrinsically photosensitive retinal ganglion cells provide substantial input into the POA and ...
