Study: Human Brain Selectively Tunes to Unfamiliar Voices during Sleep neuroscience science
While we snooze, our brain continues to monitor the environment, balancing the need to protect sleep with the need to wake up; one example of how the brain accomplishes this is by selectively responding to unfamiliar voices over familiar ones. Image credit: Wok & Apix.
“However, the functional role of such responses, and whether they reflect information processing or rather sensory inhibition is not fully understood.” During non-rapid eye movement sleep, unfamiliar voices elicited more K-complexes — a type of brain wave linked to sensory perturbances during sleep — compared to familiar voices.
Brain responses to the unfamiliar voice occurred less often as the night went on and the voice became more familiar, indicating the brain may still be able to learn during sleep.
