20 milliseconds to victory: the tiny brain that outsmarts humans

Trying to catch a fly in flight is an almost impossible task. While in movies heroes catch flies in the air with ease, in reality, this tiny insect is pre-programmed for rapid escape. A combination of specialized vision, a fast brain, and advanced balance organs makes it one of the most elusive creatures in nature.

The key to the fly's evasive ability lies primarily in its eyes. They consist of thousands of small lenses that provide a panoramic view of the environment. Furthermore, the fly's brain processes information at a rate significantly faster than the human brain: while we perceive the world at a normal pace, the fly sees it at approximately 250 frames per second. Consequently, a fast movement of our hand appears to it as a slow and clumsy motion.

Alongside vision, the fly's reaction speed is exceptional. Its reaction time is only about 20 milliseconds, compared to 250 milliseconds for a human. In the fraction of a second between identifying danger and taking off, the fly calculates the direction of the threat and directs its jump in the opposite direction.

Additionally, the fly possesses a special balance organ that acts as an internal measuring device, allowing it to change direction in the air sharply. Its antennae are highly sensitive to changes in air pressure, enabling it to sense the wind created by an approaching hand even before it visually detects the threat.

Flies possess short-term memory and can learn to be more cautious in areas where they have been targeted in the past. Moreover, when a sudden threat appears, one fly can send an immediate warning signal to others nearby. It is worth noting that due to their rapid reproduction rate, there are approximately 17 million flies for every human on Earth.
