Dispositional mindfulness co-varies with smaller amygdala and caudate volumes in community adults.

Mindfulness, a psychological process reflecting attention and awareness to what is happening in the present moment, has been associated with increased well-being and decreased depression and anxiety in both healthy and patient populations. However, little research has explored underlying neural path...
