Sleep before learning benefits memory encoding through unknown mechanisms. We
found that even a mild sleep disruption that suppressed slow-wave activity and
induced shallow sleep, but did not reduce total sleep time, was sufficient to
affect subsequent successful encoding-related hippocampal activation and memory
performance in healthy human subjects. Implicit learning was not affected. Our
results suggest that the hippocampus is particularly sensitive to shallow, but
intact, sleep.
