Vocabulary acquisition during sleep

Can we learn while asleep? To investigate this dream of mankind, we presented pairs of German words and fictitious translations for vocabulary acquisition during deep sleep. After waking, participants performed two implicit memory tests: 1) a cued-recall test and 2) a (re)learning test. For (re)learning, participants committed sleep-played translations and novel translations to memory during four learning runs. Functional MRI was performed during the cued-recall test. Behavioral data in both implicit tests evidenced unconscious relational word encoding during sleep. Hippocampus supported unconscious retrieval performance: the larger the hippocampal signal during retrieval, the better relational retrieval performance and the larger word pair-evoked EEG activity during sleep. We conclude that paired-associative memory encoding during deep sleep is feasible and supported by hippocampus.
