The hypothalamus is important for coordinating an individual’s interest in rewards with the body’s physiological state. This region integrates brain function with the physiological needs of the organism.
How does dopamine cause anorexia?
Dopamine plays a role in how we feel pleasurable reward, such as eating. For those dealing with anorexia, a leading hypothesis is that the disorder is associated with an over-production of dopamine, leading to anxiety, harm avoidance, hyperactivity and the ability to go without pleasurable things like food.

How does the reward pathway work?
The reward pathway of the brain is connected to areas of the brain that control behavior and memory. It begins in the ventral tegmental area, where neurons release dopamine to make you feel pleasure. The brain begins to make connections between the activity and the pleasure, ensuring that we will repeat the behavior.

What part of the brain is affected by anorexia nervosa?
Most fMRI studies performed in patients with anorexia nervosa focused on food, taste, physical appearance and social cognition. Although very different in terms of the study protocol, the most common findings are increased activation of the amygdala and altered activation of the cingulate cortex.
