Experiments with mice have shown that if you shock mice at certain times during sleep, their fear conditioning will change. https://academic.oup.com/sleep/article/26/5/527/2707886 https://academic.oup.com/sleep/article/26/5/527/2707886 This seems to indicate that sleep acts like an unsupervised learning reinforcer.
Sleep might be required for a certain level of consciousness.
- xkcd-sucks 7y agoYou might be interested in "hippocampal replay" and "sequence reactivation" during sleep TL;DR during sleep, most critters' brains actively "re-play" waking experiences, and this contributes to learning+memory. I can't find the paper right now, but at a talk in ~2013 some guy presented work in which spatial trajectories run by rats were reconstructed from hippocampal place cell activation sequences during sleep https://en.wikipedia.org/wiki/Hippocampal_replay https://en.wikipedia.org/wiki/Hippocampal_replay https://www.jneurosci.org/content/28/31/7883 https://www.jneurosci.org/content/28/31/7883 http://sci-hub.tw/https://doi.org/10.1016/j.neuron.2019.01.052 http://sci-hub.tw/https://doi.org/10.1016/j.neuron.2019.01.0... https://www.cell.com/current-biology/pdf/S0960-9822(17)31441-0.pdf https://www.cell.com/current-biology/pdf/S0960-9822(17)31441...
