Doves can be aware of multi-dimensional space and time

Just like people, species, symbols of peace, can be distinguished and have abstract ideas about time.

New research results published in Curent Biology (USA) show that low-level animals such as birds, reptiles and fish have the ability to make high-level abstract decisions that are thought to refer to humans. can do it.

The research team from the University of Iowa thinks that in fact, the bird's cognitive skills can get close to the level of awareness of both humans and other high-class mammals.

Specifically, in a series of experiments that this group conducted, pigeons were identified with straight lines of different lengths and appeared in intervals of 2 or 8 seconds.

The results show that pigeons can identify lines of varying length and duration. Similar experiments in high-end mammals also yielded similar results in terms of nerve coding.

Scientists also point out that unlike humans, pigeons use another area of ​​the brain to process this information.

In humans, the area receiving information about multidimensional space and time is the peak of the cerebral cortex, but the brain structure of the pigeon does not have this area so scientists believe that pigeons receive and process The above information in another area of ​​the brain.
