During deep sleep, the presence of an unfamiliar voice elicits more K-complexes, a type of brain wave linked to sensory perturbances during sleep, compared to the sound of a familiar voice.
A new framework describes how the locus coeruleus regulates the brain's sensitivity to relevant information during situations that require attention.
Increased choline consumption during pregnancy was associated with better performance in tasks requiring sustained attention in children aged seven. Researchers found doubling the recommended amount of choline by increasing consumption of nuts, eggs, red meats, and fish during pregnancy had the greatest benefits for the developing fetal brain.
Norepinephrine is locally regulated in the visual cortex. More norepinephrine is released when and where visual information is processed.
The choline transporter protein regulates habituation to smells in fruit fly brains.
Practicing mindfulness when your mind is wandering can help you regain attention, researchers report.
Brain flow occurs when a person participates in an activity that is engaging enough to involve someone to a point of barely being distracted, but not so difficult that the task becomes frustrating. Flow, researchers say, requires high levels of attention.
Researchers investigate why many of us wake in the middle of the night and dwell on our fears.
Heart rate synchronization occurs, even when people listen to a story alone, when paying attention to certain points of a story.
Researchers shed light on how the brain responds to unexpected sounds.
Researchers have identified four cognitive profiles associated with menopause. Findings reveal women who experience stronger verbal learning and memory, in addition to better attention and executive function during menopause, are less likely to experience hot flashes and depression. Women who experienced cognitive weakness had an increased risk of depression and sleep disruptions.
Reductions in reaction time, memory, and other neuropsychological problems persist for at least seven days following a ten-day period of insufficient sleep.
