Every day the human brain is presented with tasks ranging from the trivial to the complex. How much mental effort and attention are devoted to each task is usually determined in a split second and without conscious awareness.

Two common features of anxiety disorders are sleep loss and an amplification of emotional response. Results from the new study suggest that these features may not be independent of […]
