Dragonflies also have the ability to focus like humans

(A recent study suggests that dragonflies also have nerve cells to perform labor-intensive tasks - cells found only in primates. Accordingly, dragonflies do not have large brains like humans but they can still complete the work well.

Specifically, dragonflies can filter out visual information that is not necessary to focus on a certain goal, this process is called selective concentration. This is the first study to detect nerve cells that coordinate selective concentration in invertebrates, the results of the study are published in Current Biology.

Selective focus is essential to responding to the impact of a factor in dozens of attention factors at any time, said Steven Wiederman of the University of Adelaide, Australia.

According to Wiederman, the prey of dragonflies is that insects often fly in flocks. When hunting, it selects one in the herd, at which time the active stem cells will remove all the prey around and concentrate on attacking the target prey, the probability of catching the prey is 97%.

Using probe lenses with a head that is 1,500 times smaller than a hair, researchers have assessed the activities of dragonfly nerves to allow them to have such excellent hunting capabilities. In a statement, O'Carroll from Adelaide said that the brains of primates also had a similar process, but the researchers did not think this would happen with advanced insects. chemicalization 325 million years ago.

O'Carroll believes this work will appeal to neuroscientists as well as engineers.'For example, it could be a model for making robots, because insect brains are very simple and accessible. Future studies may help to understand insect insect neural networks and we can simulate it in smart robots , 'O'Carroll said.

Many other insects are also an inspiration to design robots. For example, Swiss scientists have built unmanned aircraft that mimics insect fighting ability.

Sometimes insects are also used directly to make robots. Researchers at the University of North Caronila said they created Madagascar half-wind turbines by attaching microchips to their senses to control their activity.
