Fascinating article. Here is an excerpt:

“We show that in patients with anxiety, emotional experience induces plasticity in brain circuits that lasts after the experience is over,” senior co-author Rony Paz said in a press release. “Such plastic changes occur in primary circuits that later mediate the response to new stimuli, resulting in an inability to discriminate between the originally experienced stimulus and a new similar stimulus. Therefore, anxiety patients respond emotionally to such new stimuli as well, resulting in anxiety even in apparently irrelevant new situations. Importantly, they cannot control this, as it is a perceptual inability to discriminate.”
