The Brain Has a ‘Low-Power Mode’ That Blunts Our Senses | Quanta Magazine

Melanie Boly, a neurologist and neuroscientist at the Medical School of the University of Wisconsin, Madison, is painstakingly collecting EEG data from long-term Buddhist meditators during a state known as pure presence, an experience with no self, no discursive thoughts, and no perceptual content except for a luminous expanse, an empty mirror. Att

In stark contrast to this misperception, neuroscientists have recently discovered that parts of the brain can fall asleep for a few moments or longer without our realizing it. At any given moment, some circuits in the brain may be off-line, slumbering,

Recent research discovered a startling facet of life—brief periods during which consciousness is absent while the body carries on its well-rehearsed duties: driving, doing the dishes, or reading a long and uninspiring office memo. To an observer, everything looks normal while the subject is, in fact, zoned out. During these episodes of mind blankin

baseline, “resting” state—but don’t let the word fool you, because the brain isn’t at rest at all. Instead, it experiences tonic activity in what’s now known as the DMN, the default mode network: the posterior cingulate cortex, the adjacent precuneus, and the medial prefrontal cortex. This baseline activation suggests that the brain is constantly g
