Both cerebrum and cerebellum have gray matter in their surface cortex and deeper nuclei, and white matter deep to the cortex. The hippocampus lays down memories of this rapid sense of satisfaction, and the amygdala creates a conditioned response to certain stimuli. The nucleus accumbens, on the other hand, is one of the major centers for motivation and reward in our brain.

Pleasure itself - that good feeling you get in response to food, sex and drugs - is driven by the release of a range of neurotransmitters (chemical messengers) in many parts of the brain. The existence of a pleasure center was first hypothesized in 1954 by two Canadian researchers at McGill University, James Olds and Peter Milner. Some the brain areas impacted by pleasure include amygdala, nucleus accumbens, ventral tegmental area, cerebellum and the .

The knowledge of these areas is complex, because our brain is a difficult organ to analyze and study. It communicates with each part of the body through the nervous system, a network of channels that carry electrochemical signals. Neurons in the different regions of the brain comprising the reward system communicate using dopamine: For example, dopamine-producing neurons in the brain's ventral tegmental area communicate with those in a region called the nucleus accumbens in order to process rewards and to motivate behavior. The brain is the most complex part of the human body. The hypothalamus controls sexual arousal. The Science of Addiction with Dr. Quinn T. Chipley "The pleasure principle long persists, however, as the method of working employed by the sexual instincts, which are so hard to 'educate,' and, starting from those instincts, or in the ego itself, it often succeeds in overcoming the reality principle, to the detriment of the organism as a whole." Dopamine is a neurotransmitter present in regions of the brain that regulate movement, emotion, motivation, and feelings of pleasure.
