Selective Attention in Dragonflies

Invertebrate animal also have brain cells to select an object by their vision. Many studies have been conducted on vision of insects for many years. Researchers have discovered their vision by using a tiny glass probe with 60 nanometers wide tip which is 1500 times smaller than the width of a human hair and they found neuron activity in the dragonfly’s brain that enables the selective attention. Dragonflies will switch on their brain cell to one target when they found more than one visual target and behave as there is no other target is exists. The ability of selection and the response to one sensory stimulus is fundamental in human and it was well demonstrated in previous studies. Similarly, flies are also having the ability of selection during hunting.  When the dragonfly selected a single target in a group of other insects during hunting, it’s activated it neurons and filters all other potential prey to swoop on the targeted one. Some of the researchers found that the brain activity makes the dragonfly a more efficient and effective predator.
