Loose Periquitos are originally from Australia and belong to the family of the parrots. These speaking birds of colorful plumage and bent mouth are some of the favorite pets in Europe and in America, where they are known as ‘Australian Cotorrrites’.
He Periquito in its natural habitat has a greenish plum that serves as a camouflage of possible predators. However, the domestic fellow people can find in different colors. The offspring were reached blue, yellow or white plumage parades, but they are all characterized by the possession of wavy horizontal lines ranging from the head to the wings.
In his country of origin, Australia, The parakeets live in herds of up to 2000 birds. It is not surprising that this social bird, even in captivity, prefers to be accompanied. The repertoire of sounds and their body language are extraordinary.
The Periquito: Study model in communication disorders
Man is not the only species that can speak and vocalize. The Periquitos also has vocal skills and can imitate sound noisesIncluding human speech. Now a study led by Langone Hospital, under the University of New York, has revealed that these birds and people use similar brain mechanisms to produce complex sounds.
Work, Posted in the magazine NatureShow that Periquitos can be important models to study communication disorders in people, As they can happen after a stroke.
The research team He studied neuronal recordings of two types of parrot: Periquitos and Zebra Pinzones, the last with limited vocal learning compared to Periquitos To investigate how the Vocal production.
“We discovered that There is a representation of vocal sounds in the bones part of the parakeets What is analogous to an important center of speech production in people. This is the first not -human species in which a ‘vocal motorcycle card’ has been observed, explains Michael Long, one of the study leaders.
Vocalizations Spectrum
The parakeets use the central core of the Previous arcopallium, an area of the brain of the bird that connects with the syringe (The Avian vocal organ) by the brainstem, which makes the production of a possible diverse range of vocalizations.
“Erin parakeet, Individual brain cells They code for the different sounds produced by the AVE, including the vocal tone. In other words, there is an agreement between the brain of the parakeet And a piano, in which different keys lead to different notes, “the researcher continues.
“We have Discovered a vocal keyboard; Now we would like to understand how it is played. For both people and these birds, the right sound must take place in the right context and understand how it works is essential to combat the effects of brain disorders, “concludes long.
