Chronobiology in Latin America: XIII Latin American Symposium on Chronobiology

I am glad to announce this special issue of Sleep Science that is dedicated to presented papers at XIII Latin American Symposium on Chronobiology (XIII Simpósio Latino Americano de Cronobiologia). The Latin American Symposium on Chronobiology (LASC) is a biennial international scientific meeting in which projects are presented and discussed, involving students and researchers from Latin America...

Chronobiology and Sleep Disorders

In this section on chronobiology and sleep disorders, the seven chapters describe considerable advances in this field since the Fourth Generation of Progress was published. This group of chapters seeks to integrate our basic and clinical knowledge and to convey the high level of current excitement in sleep and biological rhythm research. All these chapters present certain cross-cutting themes p...

Chronobiology and mood disorders

The clinical observations of diurnal variation of mood and early morning awakening in depression have been incorporated into established diagnostic systems, as has the seasonal modifier defining winter depression (seasonal affective disorder, SAD). Many circadian rhythms measured in depressive patients are abnormal: earlier in timing, diminished in amplitude, or of greater variability. Whether ...

Chronobiology by moonlight.

Most studies in chronobiology focus on solar cycles (daily and annual). Moonlight and the lunar cycle received considerably less attention by chronobiologists. An exception are rhythms in intertidal species. Terrestrial ecologists long ago acknowledged the effects of moonlight on predation success, and consequently on predation risk, foraging behaviour and habitat use, while marine biologists h...
