Sleep & memory review

Main thread Sonnet 4.5 24

Map the main strands of sleep and memory research so I know what to read first.

There are two dominant accounts. Under systems consolidation, hippocampal traces are gradually redistributed to the neocortex during slow-wave sleep, so memories become independent of the hippocampus over time.

The synaptic homeostasis account says sleep instead downscales synapses strengthened during the day, improving signal-to-noise for what remains.

Systems consolidation

“hippocampal traces are gradually redistributed…” What about remote memories that never become hippocampus-independent?

Synaptic downscaling

“downscales synapses strengthened during the day” Is slow-wave slope a fair proxy for synaptic strength?

Features

Main thread

Cues played during sleep bias which traces are replayed that night, strengthening them by morning.

Highlight text and ask about it. The side thread opens next to the line it came from.

Main thread

Summarise the TMR evidence. Targeted memory reactivation replays learning cues during slow-wave sleep, which biases which memories get consolidated overnight. And odour cues?

Know what each branch knows

Every thread has a context meter. Turn off what a branch carries, and add files that only apply from that point down.

Main thread

Memory cues can be replayed during sleep. Odours work especially well because smell reaches memory areas directly.

Odour cues

“Odours work especially well” Studies pair a scent with learning, then release it during deep sleep. Smell skips the thalamus, so olfactory input goes straight to the hippocampus without waking you.

Olfactory pathway

“olfactory input goes straight…” Is that true for all smells?
