The neuroscience of heartbreak. Bit silly, and as usual more of a psychology thing than a neuroscience thing, but fun. Most interesting part:

The adversity intensifies the passion according to a phenomenon called “frustration attraction”, and it’s due to the dopamine and norepinephrine rising occurring when seeking for the abandoner who broke the social tie. These two neurotransmitters are the main responsible for the chemical reactions of love, so when they increase in the attempts of winning someone back, so does your romantic passion for them.

I’d be very curious to know if it looks the same as limerance, or if it’s just another ‘look dopamine is involved in stuff’ thing. Maybe one day I’ll look it up, or one of you can tell me.
