Most people think love comes from the heart or soul. The heart simply pumps blood, so love can't be created there. Where is the center for what appears to be a person's soul? The Brain. And what is created there, Jilly? That's right--dopamine. What does dopamine do? Creates feelings of love and euphoria. How do we get our brains to create more? Drugs, massage, and/or sex. Boil it down and it's all just dopamine.
There are few things ever dreamed of, smoked or injected that have as addictive an effect on our brains as technology. This is how our devices keep us captive and always coming back for more. The definitive Internet act of our times is a perfect metaphor for the promise of reward: we search. And we search. And we search some more, clicking that mouse like – well, like a rat in a cage seeking another “hit”, looking for the elusive reward that will finally feel like enough.
Of all the chemical transmitter substances sloshing around in your brain, it appears that dopamine may be the most directly related to the neural correlates of belief. Dopamine, in fact, is critical in association learning and the reward system of the brain that Skinner discovered through his process of operant conditioning, whereby any behavior that is reinforced tends to be repeated. A reinforcement is, by definition, something that is rewarding to the organism; that is to say, it makes the brain direct the body to repeat the behavior in order to get another positive reward.
The exaggerated dopamine sensitivity of the introvert leads one to believe that when in public, introverts, regardless of its validity, often feel to be the center of (unwanted) attention hence rarely craving attention. Extroverts, on the other hand, seem to never get enough attention. So on the flip side it seems as though the introvert is in a sense very external and the extrovert is in a sense very internal - the introvert constantly feels too much 'outerness' while the extrovert doesn't feel enough 'outerness'.
This,” Alaric explained to Sarah in what he thought was a kindly voice, “isn’t love you’re feeling. Only dopamine. Because Felix isn’t like anyone else you know. Being a creature of the night, he’s new and exciting and activates a neurotransmitter in your brain that releases feelings of euphoria when you’re around him…especially because you know you can never actually be together, and he seems complicated, and perhaps even sensitive and vulnerable at times. But I can assure you: he’s anything but.”“How dare you?” Sarah demanded hotly. “It isn’t dopa…whatever! It’s love! Love!
Medications used to treat psychiatric disorders are commonly referred to as psychotropic drugs. These drugs are commonly described by their major clinical application, for example, antidepressants, antipsychotics, mood stabilizers, anxiolytics, hypnotics, cognitive enhancers, and stimulants. A problem with this approach is that these drugs have multiple indicators. For example, selective serotonin reuptake inhibitors (SSRls) are both antidepressants and anxiolytics, and the serotonin-dopamine antagonists (SDAs) are both anxiolytics and mood stabilizers.
