Dopamine—a neurotransmitter responsible for influencing motivation, pleasure, mood and learning in the brain—has experienced a bit of fame in recent years, acting as a sort of buzzword to describe a fleeting satisfaction from social media, food or shopping.

In particular, it is associated with the mesolimbic pathway, which is a brain circuit connecting the ventral tegmental area (VTA) to the nucleus accumbens (NAc), amygdala, and hippocampus.
