Depression: Dysfunction of neurons in the amygdala may be behind negative perceptions of the environment

One of the characteristics of depression is a tendency to perceive sensory stimuli and everyday situations in an excessively negative way. But the mechanisms underpinning this 'negativity bias,' which can fuel the development of depressive symptoms, had previously remained largely unknown. To shed light on the question, scientists decided to explore the amygdala and observe how it functions during depressive episodes. Their findings suggest that a depressive state alters certain...
