Precise timing is ubiquitous and of great importance for physiology and behavior. Indeed, biological timing includes diverse time-related mechanisms that encompass several orders of magnitude, from microsecond processing to seasonal rhythms.
In the Laboratory of Chronobiology we study biological timing, with special emphasis on two temporal scales: circadian timing and time estimation in the seconds-to-minutes range.
Circadian timing refers to the range of the 24-h, and governs a large array of physiological, metabolic and behavioral functions. In mammals, the circadian clock is located in the suprachiasmatic nuclei (SCN) of the hypothalamus. Most – if not all – organisms exhibit daily and circadian rhythms with periods of ca. 24-h, which also serve as the basis for seasonal-encoding mechanisms and might be related to lifespan-related processes.
Research lines
- Chronic circadian desynchronization: metabolic, cognitive and immune effects.
- Signaling pathways involved in photic synchronization of the mammalian circadian clock.
- Interactions between the circadian system and the immune system.
- Circadian regulation of cognitive and motivational processes.
- Role of glia in the intercellular communication.
- Assessment of risk factors and sleep – wake cycle in different populations at risk.
- Daily variations in decision making.
- Circadian rhythms in Caenorhabditis elegans.
