If you speed up the sound recording, it seems logical that the brain will also start working faster. However, the new study conducted by scientists from the University of Rochester and Columbia showed the opposite. The hearing shell is developed by a certain time window, regardless of its speed. The study was published in the Nature Neuroscience magazine.
The authors worked with patients who were temporarily installed to control epilepsy. Participants were heard from the same audio, both normal and slow speed. The neurons were expected to change the "Integration window" of information, but it remained the same, about 100 milliseconds.
"When you slow down the word, the hearing shell does not expand its analysis time. It continues to develop a signal at certain speed, and higher areas of the brain interpret the result, to understand words and phrases, "said one of the authors of the study.
According to the co-author of the Columbia University, this discovery challenges the traditional idea that the brain adapts to the structure, syllables and words of speech. In fact, it uses its own "internal metronoma".
Scientists hope that the understanding of this mechanism will help to model speech processing and explain why some people have hearing and linguistic development disorders.
