Scientists from the University of Dublin, together with Edmund Lalor, came to the conclusion that the human brain is capable of distinguishing one voice from the crowd. The results of their research were published on Medicalxpress.
The experiment was carried out in the laboratory of Edmund Lalor, associate professor of neurology and biomedical engineering at the University of Rochester Medical Center.
Study participants had to listen to two stories at the same time, but focus on only one. The experts then analyzed the participants’ electroencephalographic (EEG) brainwave recordings.
It turned out that the story on which the subject focused his attention turned into linguistic units – phonemes that make it possible to distinguish one word from another. As the scientists noted, the other story was not at all transformed by the participants in the experiment.
«Sounds must be recognized as corresponding to certain linguistic categories, such as phonemes and syllables, so that we can ultimately determine which words are pronounced – even if they sound different, such as pronounced by people with different accents or different voices», — explained Lalor.
This study has shown the possibility of using EEG brain wave signals, which allow you to find out who a person is paying attention to in a noise environment.
On November 22, scientists at Boston University School of Medicine named the cause of brain aging. Researchers have found that sugar, which is added to many drinks, can age the brain, affecting its function detrimentally: drinks high in sugar lead to a decrease in the prefrontal cortex over time.
