The Night Gardeners: Immune Cells Rewire, Repair Brain While We Sleep — And Stress Turns Them OFF

(Justin Deschamps) A recent study conducted by the University of Rochester Medical Center identified one of the brain systems in charge of repair and new connections. Microglia cells act as repair/connection bots for the mind, working to rewire your brain when you’re learning, whether, by study, daydreaming, getting triggered or action. What’s interesting is that stress seems to shut down this system, giving us insights into how we might maintain health into old age.

A New Discovery: How Our Memories Stabilize While We Sleep

(Science Daily) Scientists have shown that delta waves emitted while we sleep are not generalized periods of silence during which the cortex rests, as has been described for decades in the scientific literature. Instead, they isolate assemblies of neurons that play an essential role in long-term memory formation.

Nighttime Snacking Promotes Vicious Cycle Of Sleeplessness, Weight Gain, Junk Food Cravings

(Ben Renner) We’ve all been there. That late-night craving for some junk food sets in, even though it’s way too late to be eating. Most of the time all it takes is a little bit of willpower to resist, but giving in to temptation from time to time happens to the best of us. Now, a study out of the University of Arizona has found that those late night snacks may be causing a much more intricate web of health problems than anyone could predict while standing in front of the fridge at 1 in the morning.
