Stressed, anxious? Ask the brain!

(Friedrich Miescher Institute) Our actions are driven by 'internal states' such as anxiety, stress or thirst -- which will strongly affect and motivate our behaviors. Little is known about how such states are represented by complex brain-wide circuits, including sub-cortical structures such as the amygdala. In a study recently published in Science, the group of Andreas L ü thi at the FMI used a deep brain imaging technique to monitor amygdala activity in active mice and revealed the neuronal dynamics encoding behavioral states.
