Scientists have learned a mystery of sleep and the brain Medical experts have claimed to solve a scientific mystery related to human consciousness.
And the mystery of how a waking brain transforms a detail into a conscious experience, but why it doesn't happen during sleep, so the answer is hidden in our sleep.
In a new clinical study, electrodes were implanted in the heads of volunteers to help determine how the brain responds to sounds during sleep or wakefulness. Duran also responds strongly to sounds on all scales except one.
During sleep, the brain keeps the level of attentional waves low so that sleep is not affected.
That is, the brain analyzes the sound during sleep, but cannot focus on it or identify it, so the consciousness does not have any kind of sensation.
Experts who were part of the research published in the journal Nature Neurosciences said the data was obtained from electrodes implanted deep into the human brain, which enabled standardized monitoring.
He said that these electrodes were not installed for this research but for therapeutic purposes, but because of them we were able to perform brain analysis The researchers said that when sounds reach the ear, the signals travel to the brain. Previously,
it was thought that sounds did not reach the brain during sleep, but we were surprised to discover that the brain's response also occurs during sleep. It is very strong.
He further stated that the brain response during sleep is similar to that observed during wakefulness, only one thing is missing and that is the level of attentional waves.
The results, he said, would have far-reaching implications because they helped solve a historical puzzle, namely, how much our brains are aware of the environment during sleep compared to wakefulness.
He said that future research will explore the mechanisms behind this difference.
