This presentation will survey the retinal architecture, advantages, and limitations of several
lesser-known rodent species that provide a useful diurnal complement to rats and mice …

Integrating the multifactorial processes co-occurring in both physiological and pathological
human conditions still remains one of the main challenges in translational investigation …

The term masking refers to immediate responses to stimuli that override the influence of the
circadian timekeeping system on behavior and physiology. Masking by light and darkness …

Photic cues influence daily patterns of activity via two complementary mechanisms:(1)
entraining the internal circadian clock and (2) directly increasing or decreasing activity, a …

Clock gene expression is not only confined to the master circadian clock in the
suprachiasmatic nucleus (SCN) but is also found in many other brain regions. The phase …

The central circadian pacemaker (Suprachiasmatic Nuclei, SCN) maintains the phase
relationship with the external world thanks to the light/dark cycle. Light intensity, spectra, and …

The suprachiasmatic nucleus (SCN) is the master circadian clock in mammals and is
composed of thousands of neuronal oscillators expressing different intrinsic periods. These …

Modern 24‐h society lifestyle is associated with experiencing frequent shifts in the lighting
conditions which can negatively impact human health. Here, we use the degus, a species …

The biological clock expresses circadian rhythms, whose endogenous period (tau) is close
to 24 h. Daily resetting of the circadian clock to the 24 h natural photoperiod might induce …

Circadian rhythms influence virtually all aspects of physiology and behavior. This is
problematic when circadian rhythms no longer reliably predict time. Circadian rhythm …
