Budgerigars has extra voice skills

Budgerigars are some of the bird templates, and reflected in their brains. Budgie brains have a voice sound map, similar to what is found in the human brain and has not seen other birds.
“We found that there was a representation of a brain voice in the region of the key in the human brain,” says Michael Long at New York University Grossman Medical School.
Budgerigars (Mellowsittacus undulatus), Also known as parakeets, are small Australian parrots. Are View shows, Human speech is able to imitate many sounds. A Budgie called Puck had a vocabulary about 1728 words, According to Guinness World Records. “The ability to imitate vocalize is something that is very rare in animal kingdom,” Long says.
With Zetian yang, Even at Nyu’s medical school, silico probes were long used to record electric activity in Buddhism’s brains. The previous central core of Arcopallium focused was involved in the control of the voice engine. While the Buddha did calls, long and Yang changed his electrical activity.
“Our study was the first to measure the activity of the Larro brain activity,” Long says.
The couple discovered neurons in the central core of the previous Arcopallio, only when the Buddies were made specific sounds. “There are active cells for consonants,” Long said. Others make vowels, some actively pitched for sounds and others.
Long compares the structure of the brain to a keyboard. “This type of key set is, or in this case, the set of brain cells can represent each of these voice results, then he can play everything he wants,” he noted. “It’s a beautiful and elegant solution for sound voices to present the parcel”. Human brains have similar voice maps.
A long time ago and Yang repeated experiments about zebra finishes (Teeniopica gnttata), there are no voice imitation. “They have only one song they study,” Long says. “It’s a second long, sometimes less.” Perfection takes months.
Unlike Budgerigars, zebra finishes did not show the signs of a “map” of vowel sounds to show their brains. Instead, “zebra estate develops this very almost impossible song,” he says long. Budgie’s brain says that the system uses a simple and intuitive system to produce their complex calls, while fixed zebra brain brains use a complex system to do something simple.
“Neuronal activity and associated vocal behavior shows that it is closer to crazy and humans with Songbirds”, says Erich Jarvis Rockefeller University in New York.
“The almost everything you know about the exact mechanical foundations learned vowel comes from some species songs that sing quite simple songs,” says Jesse Goldberg At New York Cornell University. “Parrots, therefore, offer a tremendous opportunity both mechanisms and evolution of complex vocal learning and production”.
There are several possible reasons to evolve mimicating, he says Zhili Zhao Cornell University. One is the game. “Females prefer men with better imitation skills,” he says, and if the man loses the ability, “Female more fraudulent.” Buddles have very dynamic life social life: “They make up small groups for a few days.” After establishing a group, members begin to make distinctive “contact calls”. “People think it can be like a password for this group,” Zhaok says.
Some other qualified imitation may have their brain voice maps, suggests long: “I think it would be very strong that other parrots have the same function, but it is not explored.” It also suspects LirebirakThis is Phenomenal mime This can imitate artificial sounds like camera blinds, they have something similar.
In the long run, those who look at a long time will help us learn how to learn how their sounds will help us understand the speaking of people. Those who have strokes often have Aphasia: the inability to call the right word. “You arrive for that word and there’s not there,” he said long. “Now we fight to understand what we understand in the root of many communication disorders that people causes people.”
