Human emotions can be a positive experience or a negative experience. The brain is able to handle these emotions and prevent them from interfering with mental functioning by having a specific "executive processing" area of the cortex which inhibits the activity of the emotion-processing region. Negative emotions such as anxiety are a common psychiatric condition with nearly a dozen different disorders classified in medical literature. New research finds differing patterns of brain activity associated with each of two types of anxiety: anxious apprehension (verbal rumination, worry) and anxious arousal (intense fear, panic, or both). After watching the video discuss what is known about the neurobiological basis of anxiety. What types of drugs have been used to treat this disorder?
