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.
actual rewiring occurs in sleep
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.

But the actual rewiring occurs during periods of sleep and non-sleep deep rest.
The dirty secret of neuroplasticity is that no neuroplasticity occurs during the thing you're trying to learn, during the terrible event, during the great event. During the thing that you're really trying to shape and learn, nothing is actually changing between the neurons that is going to last. All the neuroplasticity, the strengthening of the synapses, the addition, in some cases, of new nerve cells or at least connections between nerve cells, all of that occurs at a very different phase of life which is when we are in sleep and non-sleep deep rest.
Remember, it's in these naps and in deep sleep that the actual reconfiguration of the neural circuits occurs, the strengthening of those neural circuits occurs.
when we learn we're exposed to something and then the actual rewiring of Connections in the brain occurs typically during sleep or rest periods away from the learning
indeed during sleep the hard rewiring of the nervous system occurs plasticity occurs but what you're saying is that there's a high degree of specificity meaning the specific circuits that were active and required for the learning are the specific circuits that are modified
the actual rewiring of the neurons either the Improvement or the reduction in the strength of synapsis of connections between neurons and in rare instances the addition of new neurons for neuroplasticity occurs yes when we sleep in states of deep rest or non-sleep deep rest although there's less data to support that but the actual rewiring occurs away from the stimulus

So sleep is key. Also key are periods of non-sleep deep rest where we're turning off our analysis of duration, path, and outcome, in particular, for the thing
so much so that agitation and a feeling of strain are actually required for this process of neuroplasticity to get triggered. But the actual rewiring occurs during periods of sleep and non-sleep deep rest.
now the actual rewiring occurs during sleep
It's because the actual rewiring of those circuits that we call neural plasticity, occurs during sleep, but it's triggered in those moments of incremental learning and really struggling.
