Sleep as consolidation, sleep as creation. “This substantial variability is not consistent with the idea that night-time activity replays day-time experiences for consolidation.” https://t.co/oapqj37Ec8 (http://twitter.com/zeynep/status/935135280511807489?s=17)

Adult zebra finches rehearse highly variable song patterns during sleep

Brain activity during sleep is fairly ubiquitous and the best studied possible function is a role in memory consolidation, including motor memory. One suggested mechanism of how neural activity effects these benefits is through reactivation of neurons in patterns resembling those of the preceding experience. The specific patterns of motor activation replayed during sleep are largely unknown for any system.

We show that male zebra finches (Taeniopygia guttata) frequently exhibit spontaneous song-like activity during the night, but that the fictive song patterns are highly variable and uncoordinated compared to the highly stereotyped day-time song production. This substantial variability is not consistent with the idea that night-time activity replays day-time experiences for consolidation. Although the function of this frequent activation is unknown, it may represent a mechanism for exploring motor space or serve to generate internal error signals that help maintain the high stereotypy of day-time song. In any case, the described activity supports the emerging insight that brain activity during sleep may serve a variety of functions.

if you are totally aware during the day of all the mechanical movement, the ways of your thinking, desire, then you will find at night when you go to sleep, in spite of what all the scientists say, there are no dreams.. the mind the brain is quiet because all your problems, all your activities have been dissolved during the day, if you are attentive, are watchful, aware..  then when you go to sleep there is peace..  a quiet movement.. not agitated, anxious..  therefore, the brain brings order in itself, so the brain becomes young, fresh.. it cannot be young/fresh and decisive if there is any form of hurt..  when it sees hurt the brain has no resistance
