Scientists have discovered that mantises use an unknown kind of vision

<pre>Scientists have discovered that mantises use an unknown kind of vision

A team of scientists led by Vivek Nityananda from the University of Newcastle tried to understand the nature of the complex vision of mantises, but received more new questions than answers to the old ones. Unlike other insects, mantis eyes are facing straight ahead, and it would be logical to assume that they use binocular vision, like primates. But it was not so at all.

To understand where each of the eyes of the mantis looks, scientists attached a tiny lens-sensor to them using beeswax. The procedure is painless, and the use of lenses of different colors allowed to accurately identify where the particular eye is directed. Then the point-target began to slide along the screen and the mantis unerringly “aimed” at her with both eyes.

In the second experiment, scientists went to the trick: the point suddenly split and two new runs in different directions. However, the mantis continued to control the movement of both, with different eyes. It turns out that he does not need to apply a picture from the right eye to the image from the left to get the depth of vision and to recognize the approaching object. The insect is oriented in the three-dimensional world with one eye and this type of vision is not yet known to science.

The mantis of the mantis contains only a million neurons versus 85 billion in humans, but this “computational power” is enough to provide a three-dimensional vision with scanty initial data. If scientists can understand how this works, they can create “electronic eyes” for primitive, mass robots, in which there is simply nowhere, and expensive to put complex equipment for orientation in space.
