ScienceDaily (July 2, 2012) — As each day passes, the pace of life seems to accelerate — demands on productivity continue ever upward and there is hardly ever a moment when we aren’t, in some way, in touch with our family, friends, or coworkers. While moments for reflection may be hard to come by, a new article suggests that the long-lost art of introspection — even daydreaming — may be an increasingly valuable part of life.
In the article, published in the July issue of Perspectives on Psychological Science, a journal of the Association for Psychological Science, psychological scientist Mary Helen Immordino-Yang and colleagues survey the existing scientific literature from neuroscience and psychological science, exploring what it means when our brains are ‘at rest.’

ScienceDaily (July 28, 2011) — Yale University researchers can’t tell you where you left your car keys — but they can tell you why you can’t find them.
A new study published July 27 in the journal Nature shows the neural networks in the brains of the middle-aged and elderly have weaker connections and fire less robustly than in youthful ones. Intriguingly, the research suggests that this condition is reversible.
“Age-related cognitive deficits can have a serious impact on our lives in the Information Age as people often need higher cognitive functions to meet even basic needs, such as paying bills or accessing medical care,” said Amy Arnsten, Professor of Neurobiology and Psychology and a member of the Kavli Institute for Neuroscience. “These abilities are critical for maintaining demanding careers and being able to live independently as we grow older.”
As people age, they tend to forget things more often, are more easily distracted and disrupted by interference, and have greater difficulty with executive functions. While these age-related deficits have been known for many years, the cellular basis for these common cognitive difficulties has not been understood. The new study examined for the first time age-related changes in the activity of neurons in the prefrontal cortex (PFC), the area of the brain that is responsible for higher cognitive and executive functions.
