Sentence examples for endogenous rhythm from inspiring English sources

Testosterone in both breeds followed an endogenous rhythm, not affected by the change in controlled photoperiods.

If there is no endogenous rhythm, it is impossible to determine the pacemaker sensitivity, in which case the sensitivity is typically set to 2 mV [4].

Trilobite larvae exhibit strong nocturnal activity and they swim much more actively in darkness than during daylight, suggesting a strong endogenous rhythm (Botton and Loveland 2003).

We assumed that undersensing had occurred; therefore, the ventricular sensing threshold was changed from 10 mV to 2 mV, which is a sufficiently low sense threshold, recommended in cases where there is no endogenous rhythm [4].

The molecular mechanism of endogenous rhythm generation in the SCN and in peripheral oscillators is modeled as interlocking positive and negative transcriptional and translational feedback loops of circadian gene expression [19].

The few crabs that did change their colour during the semilunar and tidal cycle were likely doing so in response to an unobserved social stimulus rather than an endogenous rhythm.

Circadian rhythms, endogenous rhythms with periods of ∼ 24 h, are driven by an internal circadian clock.

However, swimming activity of trilobite larvae of horseshoe crabs have been strongly correlated with endogenous rhythms and this is one of the common behavioural and physiological processes of many organisms inhabiting intertidal and estuarine areas (Ehlinger and Tankersley 2006).

Individual differences in the endogenous rhythms, in addition to sensitivity to light and sleep homeostasis, determine the biological basis to what we in daily life recognize as individual differences in diurnal preference (chronotype).

A possible reason for these striking differences might be that many studies did not define the time point of measurement in relation to the previous or next migraine attack, since migraine seems to involve endogenous rhythms which may also influence the autonomic nervous system [13, 14].

A population of the talitrid amphipod Talitrus saltator (Montagu, 1808) was investigated on an exposed sandy beach on the Atlantic coast of Portugal (Leirosa beach) to estimate orientation capabilities and endogenous rhythms in conditions of recent changes in the landscape (artificial reconstruction of the foredune) and beach morphodynamics (stabilization against erosion from the sea).
