It Takes Many to Tango: A Brief Survey of Chronobiology in Argentina

Corresponding author e-mail: dgolombek@unq.edu.ar Argentinean chronobiology is currently undergoing an interesting process of growth and transformation, mostly based upon the repatriation of young researchers actively involved in biological rhythm research. In this work we will present a brief history of chronobiological studies in the country, emphasizing the role of precursors in the field (ranging from sleep and melatonin studies to the first reports in liver DNA rhythms). We shall also describe the activities of the most active research groups currently involved in chronobiology in Argentina, scattered throughout the country and working, among others, on the following topics: mammalian and avian retina, circadian gene regulation, circadian rhythms in plants and photoperiodism, neuronal circuitry and regulation of Drosophila circadian rhythms, autoctonous models of biological rhythmicity, pineal and melatonin, C. elegans rhythms and mammalian entrainment pathways. Finally, we will present some bibliometric data on Argentinean scientific production in chronobiology. Publication History Article published online: 16 June 2026 © 2009. Brazilian Sleep Academy.
