What brain activity is associated with early infatuation?

The brain activity associated with early infatuation is primarily linked to the activation of dopamine reward centers. When people experience infatuation, dopamine, a neurotransmitter associated with pleasure and reward, is released in significant amounts. This release leads to feelings of euphoria, increased energy, and intense attraction to the other person. The engagement of the brain's reward circuitry during infatuation can be similar to the way the brain responds to certain addictive substances, highlighting the powerful nature of these early romantic feelings.

In contrast, serotonin levels do not experience an increase during early infatuation; rather, they may actually decrease, which can contribute to obsessive thoughts about the partner. Additionally, while there may be fluctuations in cortisol levels related to stress and excitement during the early stages of a relationship, the activation of dopamine reward centers is the most defining characteristic of this emotional state. Reduced emotional regulation could occur, but it is more of a consequence of the heightened emotional experience rather than a specific brain activity associated with infatuation.
