The reward pathway in the brain, which is initiated in response to a stimulus, such as alcohol. The stimulus (upper orange arrow) triggers the release of dopamine (blue arrows) by the ventral tegmental area (dark blue sphere). The dopamine travels to a number of different areas of the brain that then release dopamine (red arrows). These areas include the nucleus accumbens (red sphere), which initiates motor outputs (lower orange arrow) to sustain the pleasurable stimulus, the prefrontal cortex (pink), which shifts focus and planning towards the stimulus, and the amygdala, which is involved in emotions. The hypothalamus (orange sphere) is involved in coordinating the response by secreting hormones that control bodily functions
