More on stress and the brain.

There seems to be a surge recently in articles on stress in the brain. Here I point you to two pieces: work from McEwen and collaborators showing that acute stress enhances glutamatergic transmission in prefrontal cortex and facilitates working memory, and Admon et al.'s study of new recruits to the Israeli military that shows that an individual's amygdalar reactivity (i.e., predated neural sensitivity) before stress is predictive of later vulnerability to stress and stress symptoms.
