Chronobiology Meets Quantum Biology: A New Paradigm Overlooking the Horizon? [PDF]

open access: yesFrontiers in Physiology, 2022
Biological processes and physiological functions in living beings are featured by oscillations with a period of about 24 h (circadian) or cycle at the second and third harmonic (ultradian) of the basic frequency, driven by the biological clock.

One interesting and elusive two-coupled oscillator problem [PDF]

open access: yesNeurobiology of Sleep and Circadian Rhythms
Chronobiology experiments often reveal intriguing non-linear phenomena, which require mathematical models and computer simulations for their interpretation. One example is shown here, where the two circadian oscillators located in the eyes of the mollusk
