Flies see the World in Slow Motion

Mosquitoes and flies are small insects that can move swiftly. But not the ability to fly fast which makes it difficult to catch, but the vision sensor. Researchers found that the smaller animal's body size and the faster of metabolism rate, then the time will run slower for the animal. This means that the perception of time is directly related to the size of the species. Small animals are able to see in slow motion.

The findings that published in the Animal Behaviour journal at mid-September, 2013 was derived from a study of an animal's ability to detect flashes of light separately. Flicker fusion frequency of the light gives an indication of the perception of time is seen by small animal.

"Many researchers see this in different animals by measuring their perception of flashes of light," said Dr. Andrew Jackson from Trinity College Dublin, Ireland, who led the study. Interestingly, Andrew said, there is a big difference between large and small-bodied species. Small animals actually see the world in slow motion. "Flies can catch the glint of light flashing up to four times faster than human capability," he said.

The research was conducted by Jackson as inspired by a little boy who is always moving fast and in a hurry. The findings that flies see the world in slow motion also applies to humans is possible when still a child. "Flicker fusion frequency in humans is very related to a person's subjective perception of time, and will change as you age," says Andrew. Andrew examines the same thing in 30 different species, including rats, eels, lizards, chickens, pigeons, dogs, and cats.

Kevin Healy, a PhD candidate in the Faculty of Natural Sciences at Trinity College Dublin, Ireland, said that the study results support the important role of time perception in animals. Ability to perceive time in small animals may be the difference between life and death for a fast-moving organisms.

Professor Graeme Ruxton of the University of St Andrews in Scotland explains, that has eyes that send signals to the brain for at a higher frequency than the human eye is of no value if the brain does not process the information as fast." These findings highlight the ability of the brain impressive that even the smallest of animals owned. "Flies might not be deep thinkers, but they can make good decisions very quickly," said Professor Graeme. *** [EKA | FROM VARIOUS SOURCES | THE TELEGRAPH | ROSALINA | KORAN TEMPO 4349]
