    Examples include circannual or annual cycles that govern migration or reproduction cycles in many plants and animals, or the human menstrual cycle. Ultradian rhythms, which are cycles shorter than 24 hours, such as the 90-minute REM cycle, the 4-hour nasal cycle, or the 3-hour cycle of growth hormone production.

    10 microseconds (μs) – cycle time for frequency 100 kHz, radio wavelength 3 km. 18 microseconds – net amount per year that the length of the day lengthens, largely due to tidal acceleration. [3] 20.8 microseconds – sampling interval for digital audio with 48,000 samples/s. 22.7 microseconds – sampling interval for CD audio (44,100 ...

  5. Time perception - Wikipedia

    en.wikipedia.org/wiki/Time_perception

    Studies have demonstrated that many species of animals, including both vertebrates and invertebrates, have cognitive abilities that allow them to estimate and compare time intervals and durations in a similar way to humans. [25] There is empirical evidence that metabolic rate has an impact on animals' ability to perceive time. [26]

    For example, the Venus flytrap closes its trap in about 100 milliseconds. [1] The traps of Utricularia are much faster, closing in about 0.5 milliseconds. [ 2 ] The dogwood bunchberry 's flower opens its petals and fires pollen in less than 0.5 milliseconds.

  7. Stimulus filtering - Wikipedia

    en.wikipedia.org/wiki/Stimulus_filtering

    Stimulus filtering occurs when an animal's nervous system fails to respond to stimuli that would otherwise cause a reaction to occur. [1] The nervous system has developed the capability to perceive and distinguish between minute differences in stimuli, which allows the animal to only react to significant impetus. [2]

  8. Interaural time difference - Wikipedia

    en.wikipedia.org/wiki/Interaural_time_difference

    Interaural time difference (ITD) between left (top) and right (bottom) ears. (sound source: 100 ms white noise from 90° azimuth, 0° elevation). The interaural time difference (or ITD) when concerning humans or animals, is the difference in arrival time of a sound between two ears.
