Prolactin secretion- Dopamine manufactured by neurons in the arcuate nucleus of the hypothalamus is ejected into the hypothalamo-hypophysial blood vessels of the median eminence, which supply the pituitary gland. This acts on the lactotrope cells that produce prolactin. What Does Dopamine Do: The R...

“The brain in love finds the nucleus accumbens (a major reward center) linked to the frontal cortex to generate positive feelings, and has a reduced connection to the amygdala (the fear center). “Those connections reverse in the process of falling out of love. An individual finds the relat...
One of the two friends with high thresholds is a competitive swimmer, and the next day returns to a rewarding routine of strenuous work-outs and interaction with teammates. The third friend, also with a high threshold, does not feel rewards from simple daily activities, is not immersed in an...
When drugs flood the brain with dopamine (a part called the nucleus accumbens), the part of the brain involved in memories (the hippocampus) stores memories of the drug and everything associated with it. It has really strong memories of how quickly and intensely that combination of things brou...
In addition, the nucleus accumbens, which plays a role in processing reward, has been shown to beinvolved in risky behaviorsin adolescents and adults. This region is rich in dopamine and suggests a further role for dopamine in risky behaviors. ...
Mutant mice that do not synthesize dopamine die of starvation owing to a lack of motivation to eat. Restoring neurotransmission in the striatum rescues these animals, whereas restoring it in the nucleus accumbens does not [8]. Dopamine makes us feel driven, curious, and intrinsically motivated. ...
Another part of the brain called the nucleus accumbens also lit up when study participants experienced brain tingles. This brain region helps direct motivated behaviors driven by reward and satisfaction, and it activates when people experience music-induced chills. Although ASMR and music chills don...
Addictive drugs share with palatable food the property of increasing extracellular dopamine (DA), preferentially in the nucleus accumbens shell rather than in the core. However, by acting directly on the brain, drugs bypass the adaptive mechanisms (habituation) that constrain the responsiveness of ...
Our difficulty, according to Daniel Nettle, is that the brain systems for liking and wanting are separate. Wanting involves two ancient regions the amygdala and the nucleus accumbens that communicate using the chemical dopamine to form the brain’s reward system. They are involved in anticipating ...
