The amygdala is involved in our experience of emotion and in tying emotional meaning to our memories. The hypothalamus regulates a number of homeostatic processes, including the regulation of body temperature, appetite, and blood pressure.

The amygdala, in the limbic system, is the center for emotionally charged memories and persistent negative thoughts. It is active during stress, anxiety, and depression. It sits conveniently beside the hippocampus, the part of the brain that serves long-term memory.
