I don’t know which specific novel you may be referencing, but generally:
Literary devices can be used to convey theme in many ways. You can use them to convey theme by describing the setting of the story, the mood of the story, the moral of the story, and much more.
You can use foreshadowing to hint at future events important to the story, symbolism to represent important objects relative to the theme, such as a dove in heaven, and you can use a metaphor to assert that one object is another, which brings new meaning to the original subject for a renewed comprehension. These can all improve the conveyance of theme in a story.
These are just a few of the many different literary devices that you can utilize to articulate subjects within a story to add to the understanding or to signify the importance of any detail within the story.”
Dopamine is a chemical in the brain, commonly associated with motivation, goal-directed behaviours, and reward. Dopamine is also the cause for the sensation of 'novelty'. So, when you see someone you are in love with, and your brain presents heightened levels of dopamine, it makes your loved exciting on the brain. It seems special and unique, and a strong motivation towards him/her is created.
On the other hand, Norephinephrine is responsible for the extra surge or energy on your body. In a way, it is similar to the energy rush that adrenaline is responsible for. When your loved one is having an interaction with you, this chemical is released, causing you to feel a rush, you begin to get nervous maybe, or perhaps even anxious.
According to several antropologists, when these two chemicals are together, they produce "elation, intense energy, sleeplessness, craving, loss of appetite, and a very focused attention."
I hope this answer helps you, have a great day! :)
