Pathways to anxiety

There is a spectrum on which we experience anxiety. It can be an intense moment of panic, to a lingering sense of dread that lasts for days. In fact, there are two neural pathways to anxiety. Both pathways start with sensory information reporting to the thalamus (also known as your body's information station). In one pathway, information gets sent to the cortex (higher processes of the brain including memory, thinking, learning, etc.). After the cortex processes sensory information, neurons fire to the amygdala. The amygdala plays a big part in anxiety because it is here where your brain processes emotions; it is also known for the “fight or flight” response. Once information has been processed by the amygdala, your body is then cued for anxiety response. The second pathway for anxiety skips the cortex altogether and goes from the thalamus straight to the amygdala, triggering an anxiety response.
