Neural signatures of sleep in zebrafish
Fluorescence-based polysomnography in zebrafish reveals two major sleep signatures that share features with those of amniotes, which suggests that common neural sleep signatures emerged in the vertebrate brain over 450 million years ago.

The hippocampus is crucial for forming non-hippocampal long-term memory during sleep
Hippocampal activity during a period of sleep after memory encoding is crucial for forming long-term memories in rats, even for types of memory considered not to be hippocampus-dependent.

Quantitative phosphoproteomic analysis of the molecular substrates of sleep need
A subset of synaptic proteins are cumulatively phosphorylated during wakefulness and dephosphorylated during sleep, in accordance with sleep need; this may represent a common mechanism underlying regulation of both synaptic homeostasis and sleep–wake homeostasis.
