Why can a cat owl correctly locate a prey?

Even in the dark night, the owl can easily locate the position on the prey, thanks to the very sophisticated sound signal processing system in its brain.

According to a recent study conducted by Dr. Masakazu Konishi of the California Institute of Technology and colleagues, for example, with a rustling noise of a mouse treated with a two-way audio map, still allow The owl cat immediately knows where the bait is. This discovery is important for the study of brain processing information.

In addition, to find out how the owl species can catch prey in the dark, the team looked at the response of 14 cat owls to sound pairs. Cell stimuli recorded in the brain show that the owl's auditory system has created a two-dimensional sound map, based on the sounds obtained. After that, the system multiplies the sounds to more accurately locate the time and place where the sound is coming from.
