For the first time, a study confirms that blind people also have the ability to locate echoes such as bats and dolphins, according to Top News.

There are blind people who can make tongues and use sounds that come from those sounds to identify their surroundings. Some people are so good at positioning that they can use this ability in strange environments, and participate in activities such as climbing or playing basketball. go

Researchers at the Brain Center at the University of Western Ontario (Canada) have recently shown that blind people have used the brain's 'visual' part of the brain to handle tongue clogging and echoes when 'seeing' objects . This is the first study to examine the neurological basis of human echolocation.

' Echo-based positioning allows blind people to do what is supposed to be impossible due to lack of vision, and can provide blind people with a high level of independence ', said Mel Goodale, director of China. Mind of mind and leader of the research team, said. Researchers found this when taking a brain scan of two volunteers 43 and 27 years old who were blind from babies.

Mr. Goodale and his colleagues recorded tongue twitches and weak echoes through tiny microphones in the ears of blind people as they stood outside and tried to identify different objects such as cars, flagpoles, trees .

The team then reopened the tape recording for blind people hearing and measuring their brain activity with a modern magnetic resonance brain scanner. It is noteworthy that when the above recordings are given to blind listeners, they not only perceive objects based on echoes, but also show positive activity in areas of the brain that normally process visual information. in people with normal vision.

According to experts, the study helps researchers understand more about brain function, especially how the senses are handled and what happens neurologically when a sense is lost.

The study is published in the journal PloS ONE .
