What's so amazing about pigeon eyes?

Put the pigeon on the edge of the conveyor belt, let the medicine boxes pass in front of the pigeon in turn, and feed it some food as a reward every time the pigeon catches the unqualified medicine box. After such training for a period of time, pigeons can go to work for others. They are very competent "inspectors"

The nerve of pigeon eye is quite developed, with more than 654.38+00000 nerve cells. With this, pigeons can find flying eagles at a distance invisible to human eyes, and can distinguish whether vultures are eating carrion or eagles are eating creatures. Pigeons are monogamous birds. With its eyes, it can recognize its spouse among hundreds of pigeons. Even after leaving the nest for a long time, it can know its home once it returns to its hometown.

Bionics has confirmed that the pigeon's eyes have these abilities because there are six kinds of ganglion cells in its retina, some bright, some horizontal and some horizontal, and the division of labor is clear, each performing its duties and not interfering with each other. Pigeons who are waste inspectors only use the directional edges of the pipeline (objects moving in a fixed direction and all edges). This ganglion cell "turns a blind eye" to the light intensity and color of the external environment, and does not respond. It only sees the edge of the object moving in a fixed direction, while the edge of the object moving in another direction does not respond. ) of the kind of nerve cells.

The medicine box on the conveyor belt always moves in a fixed direction, so in the eyes of pigeons, the quality of the medicine box is of course fast and accurate.

According to the structure of pigeon eye, people simulated the electronic pigeon eye. However, compared with the real pigeon eye, it is still far from it! But electronic pigeon eyes can be used in national defense. The radar hand of the frontier station is on duty day and night, guarding the frontier of the motherland warily. Once the enemy plane breaks into the airspace, it can be quickly found and effective measures can be taken immediately.
