In the pigeon brain there is a 'space map', so you know where to fly

Why can pigeons always find their way home? The British newspaper 'Daily Mail' has an article saying that scientists from the University of Zurich - Switzerland have come to the conclusion: in the pigeon brain there is a spatial map, so there is Can fly to strange areas, and judge the exact flight direction.

University of Zurich biologist Nicole Blazer said: " Doves have the ability to differentiate space , knowing the space between them compared to the house." Some prediction theories assume that in the brain of doves there is an imaginary map, so that they are able to recognize.

Doves have the ability to distinguish space.

In experiment, Blazer and his colleagues installed mini-type GPS recorders on the mail-carrying dove, to facilitate its route monitoring. The researchers divided the pigeons into two groups: the group was full and the hungry group, and set up three places: one was a pigeon house, the other was a place to eat pigeons, and three was a strange place 2 The location is over 30 miles. There are natural obstacles that dream the visual contact between the pigeon drop location and the two familiar places of the pigeon (home and feeding place).

'As we expected, the pigeons who eat well will fly straight home' . Neurosurgeon Professor Hans Peter Lips of Zurich University said, 'They have started flying towards their homes, just under the wrong direction of the terrain, they temporarily deviate from the route, flying around. Just a little bit '. And the hungry pigeons are different, we flew right from the beginning to the direction of feeding.

In the pigeon brain there is a type of map that can find flight paths, also able to recognize.

Blazer said that pigeons can determine their position and the relative direction of the target, and can even choose between many different goals. Therefore, it can be concluded that in the pigeon brain there is a kind of map to find flight path, also able to identify.

In addition, there has been a study in the United States previously conducted an analysis of sound waves data at the exact location of their doves and flight paths. As a result, pigeons can fly home, mainly based on the help of ' infracsound ' , forming their own 'sound map' , helping pigeons even though How far you can fly, you can easily find your way back home.
