The Link Between Wandering and Sleeping Minds
Annie Melchor | Oct 1, 2021
Researchers discover that when the mind wanders or goes blank, some parts of the brain behave as they do during sleep.
Clues to the Origin and Function of the Brain’s Alpha Waves
Amanda Heidt | Oct 1, 2020
Patterns of neural activity known as alpha waves, long thought to originate in the thalamus, may actually stem from a different brain region entirely.

Study Raises Questions About Brain Stimulation Boosting Memory
Ashley Yeager | Nov 1, 2017
In people with epilepsy, transcranial alternating current stimulation (tACS) does not affect memory-related brainwaves as widely claimed, researchers report.
Mysterious Brain Waves May Connect REM Sleep with Visual Experiences
Phil Jaekl | Jul 16, 2017
New methods could propel investigation of neural “PGO” wave patterns that may underlie critical aspects of visual experience, dreaming, and even psychosis.
