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 ...
The fruitless gene (fru) is a Drosophila melanogaster gene that encodes several variants of a putative transcription factor protein.Normal fruitless function is required for proper development of several anatomical structures necessary for courtship, including motor neurons which innervate muscles needed for fly sexual behaviors.

The flies "avoided" areas that caused them to receive heat. These experiments show that Drosophila can use operant behaviour and learn to avoid noxious stimuli. However, these responses were plastic, complex behaviours rather than simple reflex actions, consistent more with the experience of pain rather than simply nociception.
Houseflies process visual information around seven times more quickly than humans, enabling them to identify and avoid attempts to catch or swat them, since they effectively see the human's movements in slow motion with their higher flicker fusion rate. [5] [6]
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.
Diptera is a large order containing more than 150,000 species including horse-flies, [a] crane flies, hoverflies, mosquitoes and others. Flies have a mobile head, with a pair of large compound eyes, and mouthparts designed for piercing and sucking (mosquitoes, black flies and robber flies), or for lapping and sucking in the other groups. Their ...
Despite the occasional pilot informing passengers (proudly) of an intention to “make up time in the air,” people usually assume planes are going as fast as they safely can, like a speed limit ...
There is fast adaptation and slow adaptation. Fast adaptation occurs immediately after a stimulus is presented i.e., within hundreds of milliseconds. Slow adaptive processes can take minutes, hours or even days. The two classes of neural adaptation may rely on very different physiological mechanisms. [2]
