When faced with a difficult decision, it is often suggested to “sleep on it” or take a break from thinking about the decision in order to gain clarity. But new brain imaging research from Carnegie Mellon University, published in the journal “Social Cognitive and Affective Neuroscience,” finds that the brain regions responsible for making decisions continue to be active even when the conscious brain is distracted with a different task. The research provides some of the first evidence showing how the brain unconsciously processes decision information in ways that lead to improved decision-making.

A study from Karolinska Institutet in Sweden has shown that neurons in our brain ‘mirror’ the space near others, just as if this was the space near ourselves. The study, published in the scientific journal Current Biology, sheds new light on a question that has long preoccupied psychologists and neuroscientists regarding the way in which the brain represents other people and the events that happens to those people.

New drugs which may have the potential to stop faulty brain cells dying and slow down the progression of Parkinson’s, have been identified by scientists in a pioneering study which is the first of its kind.

Neuroscientists have discovered that a virtual-reality hand, which is synchronized to “pulse” in time to an individual’s heartbeat, creates the illusion in the brain of “body ownership” – with the brain believing the hand is part of its own body.

Cornell researchers have developed a reliable method to distinguish memory declines associated with healthy aging from the more-serious memory disorders years before obvious symptoms emerge. The method also allows research to accurately predict who is more likely to develop cognitive impairment without expensive tests or invasive procedures.

People who suffer from the common gastrointestinal disorder irritable bowel syndrome (IBS) have more stress-related memory problems than others, according to a new study. The researchers also found that levels of the stress hormone cortisol were related to poor memory performance. While stress has long been known to affect gut symptoms, this is the first study showing that stress also impacts on cognition in IBS.

In a new study using functional magnetic resonance imaging (fMRI), researchers have found that the same brain networks that are activated when you’re burned by hot coffee also light up when you think about a lover who has spurned you.
