A group of researchers from Germany has created a unique magnetic resonance imaging (MRI) machine that allows you to examine the brains of birds from a distance. The capabilities of the new equipment have already been tested on pigeons, having managed to obtain images without resorting to anesthesia.

The pigeons in the new study have been trained by scientists to open and close their beaks in response to specific colors. At the same time, it became known that a wide variety of brain regions are involved in this simple task in birds. The uniqueness of this study, the scientists note, lies in the fact that within its framework, specialists managed for the first time to obtain a complete picture of the bird's brain.
In the future, researchers expect to continue working in this direction and develop even more complex cognitive tasks for pigeons. In their opinion, this approach will make it possible to more accurately establish the degree of intelligence of birds, especially since there have been lively debates around this indicator in the scientific community.
