A new study has found that we don't just hear what's going on during sleep but we can actually learn new things!
As strange as this sounds the study that was carried out has provided enough evidence that we can memorize new words while we are asleep. Two groups of people were brought and given some word pairs to memorize.
During the night a group was asked to sleep while the second group stayed awake. Both groups were then allowed to listen to the words they learned earlier then in the next morning both groups took a test.
And guess what? Those who heard the words again while they were asleep did better on the test than those who heard them while they are awake! This study doesn't just show that our ears do work while we are asleep but it actually shows that our memory functions keep working during sleep as well.
Using electrodes implanted directly on the human cortex, a Johns Hopkins University undergraduate has located the part of the brain that appears to process sounds while people sleep. This site, in the frontal lobe, may be part of a vigilance system that, for instance, rouses a mother when her baby cries but lets the woman sleep when a truck rumbles by.
