Interesting Fact - Love
(Using MRI scans they have been able to monitor the physical effects of love, resulting in the first empirical evidence of love-related alterations to the brain. They have found that several areas of the brain show increased activity in people who are in love, including in the parts of the brain linked to reward, motivation, emotion regulation, and the social cognition network.
These results shed light on the “underlying mechanisms of romantic love” and could pave the way for a brain scan that could act as a “love test”.
So the next time someone says, "I love you", you can answer, "Prove it", put on this brain scanner.)
