Budgerigars have extraordinary vocal abilities

Budgerigars are some chickped birds, and it is reflected in their brain. Buggy is a map of vocal sounds in the brain, which is the same in the human brain and has not been seen in any other bird.
“We found that one part of the brain represented vocal sounds that corresponds to a major speech field in the human brain,” says Michael Long But New York University Grosman School of Medicine,
Budgerigars (Flattery), Also known as paratals, natives of Australia are small parrots. He is a magnificent vocal learner, capable of mimicking various types of sounds including human speech. A bud called Pak had a terminology of about 1728 words, According to Guinness World RecordsSays Long, “The ability to copy outspokenly is something that is extremely rare in the animal empire.”
with Zetian Yang, Even at NYU’s medical school, long used silicon probes, which was to record electrical activity in the brain of beauty. He focused on the central nucleus of the anterior arcopailium, the part of the anterior, known for joining the motor control of the vocalization. Like -As the boys called, Long and Yang tracked how their electrical activity changed.
“Our study was the first to measure the activity in the parrot’s brain during vocalism,” Long is called.
The pair found neurons in the central nucleus of the anterior arcopailium that were only active when the Bugis made specific voices. “There are cells that are active for dishes,” Long is called. Others vowels, some for some high-picked sounds and others for less-picked.
For a long time, this brain structure compared to a keyboard. “It is a set of such keys, or in this case, a set of brain cells, which can represent each of these vocal results and then play what he wants,” they say. “What the parrot has presented is this beautiful, elegant solution to create vocal sounds.” There are similar vocal maps in the human mind.
Long and Yang repeated their experiments on Zebra Finch (Teniopia), Which are not outspoken copy. “They have a single song that they learn,” says Long. “This is a second long, sometimes short.” It takes them months to complete it.
Unlike Boodgerigars, Zebra Finch showed no sign of “map” of vocal sounds in his mind. Instead, “A zebra Finch really develops almost impervious code for his song”, says Long. He says that the buggy brains use a simple and intuitive system to produce their complex calls, while zebra finch brains use a complex system to make something simple.
“It indicates that nerve activity and associated vocal behavior is close to parrots with parrots and humans,” says Erich jarvis At the University of Rockfeller in New York.
“Almost everything we know about the detailed mechanical basis of learned assertiveness, comes from some species of songbirds that sing relatively simple songs,” says Jessie Goldberg At the University of Cornell in New York. “Parrots therefore provide an incredible opportunity to study both mechanisms and complex outspoken learning and development development.”
There are many potential causes of bugs that have developed mimicry, say Swear At Cornell University. There is a courtship. “Women actually like men who have better copy abilities,” they say, and if the male loses, “the woman becomes more likely to cheat on her”. Budgians also have a very dynamic social life: “They form small groups for a few days.” Once a group is established, members start making specific “contact calls”. “People think it can be like a password for this group,” says Jhao.
Other efficient mimic may have similar vocal maps in their brain, suggest longer: “My very strong estimate will be that other parrots have the same feature, but it is not just discovered.” He also suspects that Lirebords, who are unprecedented copys that can imitate artificial sounds such as camera shutters, is something similar.
In the long run, long hope is to study how the buggy generates its voice, will help us understand speech disorders in people. People who have strokes often experience covenant: inability to keep the right word in mind. “You will arrive for that word and it’s not there,” says Long. “Now we have the possibility of understanding that I think at the root of many communication disorders who affect people with disastrous ways.”
