Dopamine plays many roles in the brain. It is related to movement, motivation, and reinforcement of behavior.
Dopamine appears to exert significant effects in two regions of the brain's cortex, the motor cortex, and the insular cortex. The insular cortex is critical for many cognitive functions related to the perception of the body's internal states, including physical and emotional states.

Dopamine, like other neurotransmitters, helps neurons communicate with each other over short distances. Most of the brain's dopamine is produced in the midbrain by neurons that connect to the striatum.
High dopamine concentrations do not make the neurons more active. However, they do make the neurons remain active for a more extended period of time, suggesting a longer response to the reward. It may have something to do with how dopamine promotes learning, which is one of its main functions.

Researchers set out to determine if dopamine might affect more distant locations in the brain.
The regions that showed the most significant surges in activity in response to dopamine were the motor cortex and the insular cortex. The findings can help researchers understand the effects of dopamine in the human brain, including its roles in addiction and learning.

Many mental health disorders can skew the ability to evaluate the cost and rewards of an action, such as anxiety and depression.
A depressed person may undervalue potentially rewarding experiences.
Neuroscientists have now identified a brain circuit that is critical for maintaining cost and reward motivation.
Researchers are working on possible drug treatments that could stimulate this circuit. They suggest that training patients to enhance activity in this circuit through biofeedback could offer another potential way to improve their cost-benefit evaluations.

Consciousness is everything you experience - taste, pain, love, feeling. Where these experiences come from is a mystery.

What is it about brain matter that gives rise to consciousness? In particular, the neuronal correlates of consciousness (NCC) - the minimal neuronal mechanisms jointly sufficient for any conscious experience.
Consider this question: What must happen in your brain for you to experience a toothache?
The whole brain can be considered an NCC because it generates experience continually.
