Nature: Don't eat late-night memory better

Recently, Nature magazine published a new study online by Amata Sehgal of the University of Pennsylvania and her team called "Availability of food decisions", "need for sleep in memoryconsolidation."
study found that the ease with which food is obtained determines the size of the need for sleep during memory consolidation.
researchers used fruit flies to test whether sleep was associated with the formation of appetite memories.
they trained hungry fruit flies in olfactory reflexes and then assessed their sleep in agar or sucrose tubes.
study showed that fruit flies that ate after training needed sleep to consolidate their memory, while hungry fruit flies' memory was not affected by sleep deprivation.
further studies have found that the memory of a full fruit fly is mediated by the front and back α'/β' neurons of the mushroom body, while the formation of the memory during hunger is mediated by the inner α'/β' neuron.
, sleep-dependent and sleep-non-dependent memories are controlled by different dopamine-energy neurons.
different α'/β' neurons mediat sleep-dependent and sleep-dependent memory, sleep and memory are coupled, so the mushroom neurons needed for sleep-dependent memory can also promote sleep.
the hunger signal neuropeptide F (NPF) in fruit flies, they also exhibit sleep-dependent memories in cases of hunger, suggesting that the choice of memory path path is determined by hunger.
sleep-dependent memory in general, the study found that fruit flies need sleep to form memories when they are full.
the researchers speculate that eating leads to the accumulation of decomposing metabolic waste, which increases energy demand and triggers a need for sleep and sleep-dependent memory.
, sleep-dependent memory promotes sleep after training, thus coupling sleep with memory.
but in order to survive in a food-deprived environment, fruit flies have developed new memory mechanisms without reducing foraging.
, the formation of memory consolidation mechanisms that are not dependent on sleep may provide evolutionary advantages.
