Standard models of perception are stimulus-driven, meaning that the external perceptual event drives the brain's perception-related activity. However, the tide may be turning: recent ideas suggest that our perceptual experiences ...
(Medical Xpress)—When you walk into a darkened room, your first instinct is to feel around for a light switch. You slide your hand along the wall, feeling the transition from the doorframe to the painted drywall, and then ...

Like scratchy-sounding old radio dials that interfere with reception, circuits in the brain that grow noisier over time may be responsible for ways in which we slow mentally as we grow old, according to the results of new ...

Like Duke Ellington's 1931 jazz standard, the human brain improvises while its rhythm section keeps up a steady beat. But when it comes to taking on intellectually challenging tasks, groups of neurons tune in to one another ...

The brain holds in mind what has just been seen by synchronizing brain waves in a working memory circuit, an animal study supported by the National Institutes of Health suggests. The more in-sync such electrical signals of ...
