According to the passage, what does the hippocampus do during deep sleep?

Replays experiences and transfers durable parts to the cortex (The passage states the hippocampus "replays the day's experiences and gradually transfers the durable parts to the cortex.")

What practical advice follows from the science described?

Read a little each day with sleep between sessions (Because consolidation happens during sleep, spaced daily reading "lets each night's consolidation lock in" the prior day's effort.)

"Consolidation," as used here, most nearly means:

the strengthening and storing of memories (The passage uses "consolidation" for the process by which the brain stabilizes and stores what was learned.)

Based on the passage, what would happen to a student who stays up all night rereading before a test?

They would skip the sleep their brain needs to store what they studied (Consolidation happens during sleep, when the hippocampus transfers the durable parts to the cortex. An all-night session trades away that step, which is why the passage says "cramming fights your own biology.")

Why Sleep Finishes Your Reading: Level 3 Reading Comprehension Questions

When you finish a chapter, your brain is not done with it. During sleep, especially deep slow-wave sleep, the hippocampus replays the day's experiences and gradually transfers the durable parts to the cortex for long-term storage. This is why a passage that felt slippery at night can seem clearer the next morning: the material was reorganized while you rested.

The practical lesson is that cramming fights your own biology. Reading a little each day, with sleep between sessions, lets each night's consolidation lock in what the previous day's effort began. Spacing your practice is not a sign of weak commitment; it is the schedule the memory system was built to use.
