Washington: A researcher has claimed that to develop better treatments for anxiety disorders, a more specific understanding of brain circuits producing the anxiety is necessary.Kay Tye, an assistant professor of brain and cognitive sciences and member of MIT`s Picower Institute for Learning and Memory, said that the targets that current anti-anxiety drugs are acting on are very nonspecific.Tye said that they don`t actually know what the targets are for modulating anxiety-related behaviour.In a step toward uncovering better targets, Tye and her colleagues have discovered a communication pathway between two brain structures - the amygdala and the ventral hippocampus - that appears to control anxiety levels. By turning the volume of this communication up and down in mice, the researchers were able to boost and reduce anxiety levels.
