When you finish a chapter, a new memory may still be fragile. Consolidation is the process that helps memories become more stable. It can happen during waking hours as well as sleep.
During sleep, patterns of brain activity linked to earlier learning can be reactivated. Researchers study how this activity, including communication between the hippocampus and cortex, contributes to memory. These brain regions do not simply move complete memories from one storage box to another.
Sleep can support learning, but it does not guarantee that every detail will be remembered. Avoid trading a regular night's sleep for hours of extra rereading. Return to the material on another day, try recalling it, and check what you missed. Rest and active review have different roles; neither makes the other unnecessary.
