Alcohol’s Effects on Sleep May Be More Prono…

Researchers have known for decades that alcohol can initially deepen sleep during the early part of the night but then disrupt sleep during the latter part of the night; this is called a “rebound effect.” A new study of the influence of gender and family history of alcoholism on sleep has found that intoxication can increase feelings of sleepiness while at the same time disrupt actual sleep measures in healthy women more than in healthy men.
Results will be published in the May 2011 issue of Alcoholism: Clinical & Experimental Research and are currently available at Early View.

Sleep makes your memories stronger

Sleep makes your memories stronger

As humans, we spend about a third of our lives asleep. So there must be a point to it, right? Scientists have found that sleep helps consolidate memories, fixing them in the brain so we can retrieve them later. Now, new research is showing that sleep also seems to reorganize memories, picking out the emotional details and reconfiguring the memories to help you produce new and creative ideas, according to the authors of an article in Current Directions in Psychological Science, a journal of the Association for Psychological Science.
“Sleep is making memories stronger,” says Jessica D. Payne of the University of Notre Dame, who cowrote the…


Sleep apnea linked to cognitive difficulties and deficits in gray matter

Sleep apnea linked to cognitive difficulties and d…

Patients with obstructive sleep apnea (OSA) may blame their daytime difficulties on simple sleepiness, but new research suggests that their brains may be to blame. Specifically, their cognitive challenges may be caused by structural deficits in gray matter, brought on by the intermittent oxygen deprivation that comes with OSA. The good news is that these deficits may be partially or fully reversible with early detection and treatment, according to Italian researchers.
“OSA patients demonstrate several neuropsychological impairments, but current knowledge of the brain structures affected by OSA is limited. This study provides the…

In recent years, much sleep research has focused on memory, but now results of a new study by University of Massachusetts Amherst psychologist Rebecca Spencer and colleagues suggest another key effect of sleep is facilitating and enhancing complex cognitive skills such as decision-making.
In one of the first studies of its kind, Spencer and postdoctoral fellow Edward Pace-Schott investigated the effects of sleep on affect-guided decision-making, that is decisions on meaningful topics where subjects care about the outcome, in a group of 54 young adults. They were taught to play a card game for rewards of play money in which wins and losses…

Napping in a hammock is one of the more delightful tasks of summer, and Swiss researchers say they now know why.
The gentle rocking motion makes people fall asleep faster, and they sleep deeper. Those changes in brain activity may inspire new ways to help insomniacs, the researchers say.
Neuroscientists at the University of Geneva rigged up a bed so it would sway gently from side to side every four seconds, considerably slower than the pendulum on a cuckoo clock. “This rocking is very gentle, very smooth, oscillating every four seconds,” Sophie Schwartz, a professor of neurology who led the study, told Shots. “It’s…
