"Let’s talk about love. How does love rewire the brain? When we meet somebody new and exciting they invade our synapses like a virus, triggering neurochemicals that feed into attraction, arousal, even obsession. We get distracted. We think about that special someone all the time. Even in the middle of a brilliant stimulating lecture. But we’re not just thinking about them, we’re building an internal model. A simulation that helps us predict what they’ll think or how they’ll feel. Of course relationships get into trouble when the simulation meets reality. Which begs the question; Do we ever really fall in love with another person, or just our idea of who they are?"
