Dog breeds with short snouts in the brain sent mixed with as much as 15 degrees. The region of the brain that controls odor was moved, according to researchers from the University of New South Wales and Sydney University. They used magnetic resonance imaging to analyze the brains of dogs for some breeds.
The size and shape of the skull appeared to be correlated with brain and rotation speed positioning of the olfactory lobe. If the dog's head and skull shape flatter, brain run ahead, while the smell center goes down to the lowest position in the skull. Human intervention in the dog through breeding biology can not be compared with the effects of another animal. Researchers continue to further examine how changes in the brain of the organization is linked to differences in dogs' brains.
Artificial selection has resulted in varieties that work better when in visual contact with humans, sheep dogs and gun dogs are the most obvious examples. These varieties are better able to understand a pointing gesture. Scientists at Eötvös University in Hungary have studied the effectiveness of different varieties within the meaning of gesture ways to man. The study aimed to shed light on the evolution of human communication skills.
Dogs have been selected to live in a human environment and are involved in interaction with people in more than ten thousand years. Hungarian researchers have found the gun dog and herding dogs to follow a pointing finger, but not hunting dogs, dogs used to hunt underground or cattle guard dogs and sled dogs.
Breeds with short noses and eyes must be centrally located to better interpret gestures towards varieties long noses and eyes that are prevalent. This is probably because the retina of the location that offers the best visual acuity.
Researchers at the University of Vienna, Austria had shown that dogs can be complex color photographs and share them in separate categories like humans. She had also shown that dogs can learn using a computer-automated touch screen. This method showed that it could be useful for testing and learning strategies, comparing cognitive abilities of different breeds.
While some researchers examine how people have worked with dogs and genetic basis of this interaction, other researchers identified the link between aggression in dogs and genes involved in neurotransmission in the brain.
Many healthy dogs are killed because they have behavioral problems, especially if they are aggressive towards people. To study the correlation between genes and aggressive behavior in dogs may help us better understand the interplay between genetics and environmental factors that affect dogs' behavior.
