Chronic stress influences our mood and behavior. Scientists of the "Max Planck – Weizmann Laboratory for Experimental Neuropsychiatry and Behavioral Neurogenetics" investigated the molecular mechanisms of how the brain reacts to stress. For the first time, they could link changes in the level of the microRNA molecule miR19b in stress-related brain areas to different behavior in mice. These findings may pave the way for a better understanding of the way our brain copes with stress.
