Sleep Loss Hijacks the Brain's Activity During Learning
Sleep is crucial for consolidating our memories, and sleep deprivation has long been known to interfere with learning and memory. Now a new study shows that getting only half a night's sleep - as many medical workers and military personnel often do - hijacks the brain's ability to unlearn fear-related memories.
