Episode notes
Sleep Spindles and Motor Development
- Sleep spindles, bursts of electrical activity during stage two non-REM sleep, spike around twelve months of age.
- This coincides with increased motor skill learning and coordination, suggesting a link between sleep and motor plasticity.
Naps and Generalization
- Infants who nap after learning new sounds extract generalized grammatical rules, not just individual facts.
- This ability to generalize knowledge, unlike computers, highlights a key aspect of human learning enhanced by sleep.
Sleep and Memory Consolidation
- Sleep before learning prepares the brain for memory acquisition, like an empty inbox.
- Sleep after learning consolidates those memories, transferring them from the hippocampus (short-term) to the cortex (long-term).
