The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
and that no matter what your intelligence is and no matter what your sleep spindle density is, if you're learning something during the day and increase your sleep spindle density, it's really almost perfectly correlated with our ability to consolidate that information and incorporate it into the schema that we already have in our brain.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
these sleep spindles are ideally designed at the frequency at the sort of tickling level of neurons to stimulate exactly what we think is the underlying basis of strengthening a memory which is at the level of the neurons the strengthening of synapses
so at the peak of the deep slow wave on its awesome rise up that's the burst that's when you get the burst additionally of the sleep spindle so if i could convert it to a sound which we've done you would get these slow waves which would sort of sound like and then often riding on top of those slow waves you'll have a sleep spindle so you'll sort of have like and that is the sleep spindle it's this burst of faster frequency activity and the coupling of those two seems to be critical in terms of things like long-term memory transfer shifting memories from short-term to long-term so you protect them and make them safe those spindles also seem to have a role in terms of triggering the strengthening of connections between brain cells something that we call brain plasticity or long-term potentiation within the brain
