A dichotomy between slow "temporal envelope" cues and faster "temporal fine structure" cues has been proposed to study several aspects of auditory perception (e.g., loudness, pitch and timbre perception, auditory scene analysis, sound localization) at two distinct time scales in each frequency band.
The most well-known version of this illusion is known as the stopped-clock illusion, wherein a subject's first impression of the second-hand movement of an analog clock, subsequent to one's directed attention (i.e., saccade) to the clock, is the perception of a slower-than-normal second-hand movement rate (the second-hand of the clock may ...
An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...
Neural receptor cells that process and receive stimulation go through constant changes for mammals and other living organisms to sense vital changes in their environment. Some key players in several neural systems include Ca 2+ ions (see Calcium in biology ) that send negative feedback in second messenger pathways that allow the neural receptor ...
The presence of female flies eating or ovipositing on a carcass may attract other female flies to do the same, perhaps through chemical cues. [12] Females exhibit preference for certain oviposition conditions over others; they attempt to maximize the survival potential of their offspring by laying eggs in only the best places.
The photoreceptor cells R1-R6 express the opsin Rh1, [145] which absorbs maximally blue light (around 480 nm), [146] [147] [148] however the R1-R6 cells cover a broader range of the spectrum than an opsin would allow due to a sensitising pigment [149] [150] that adds two sensitivity maxima in the UV-range (355 and 370 nm).

Evaluating the Spirit and United situation, Mann said that usually airplanes looking to make up speed will fly lower, “but in this case, it could be due to the United aircraft operating at a ...
The majority of insects have two pairs of wings. Flies possess only one set of lift-generating wings and one set of halteres. The order name for flies, "Diptera", literally means "two wings", but there is another order of insect which has evolved flight with only two wings: strepsipterans, or stylops; [2] they are the only other organisms that possess two wings and two halteres.
