Adult-Born Neurons Strengthen Memories While Mice Sleep
Ruth Williams | Jun 4, 2020
The activation of young brain cells in adult mice is necessary not just for forming memories, but consolidating them during rapid eye movement sleep, a study shows.
NPSR1 Variant Linked to Less Sleep in People: Study
Emily Makowski | Oct 16, 2019
“Short sleeper” mice engineered to have the same sequence in the gene sleep less but show the same performance on memory tests as animals that sleep a normal amount.
Karaoke-Sleep Study Links Disrupted REM With Poor Memory Processing
Katarina Zimmer | Jul 11, 2019
An unusual experiment suggests that interrupted REM sleep can interfere with the amygdala’s ability to process emotional memories overnight—in this case, the distressing memories of listening to oneself sing out of tune.
Growth-Promoting Protein Linked to REM Sleep in Rats
Shawna Williams | Nov 11, 2017
Brain-derived neurotrophic factor affects onset and duration of REM in the animals, but not other phases of sleep.

Researchers Pinpoint Neurons Behind Sleep Paralysis in Rats
Joshua A. Krisch | Dec 12, 2016
When glutamate neurons are inactivated in rats, the rodents are still capable of REM sleep—but they lose the sleep paralysis unique to REM.
Brain Listens During Sleep
Tanya Lewis | Jun 15, 2016
People continue to hear and process words during light non-REM sleep, a study shows.
