response: To go into more detail, the neurological process is believed to include anterior cingulate cortex, which is in the brain.
original_response: I have experienced the pain from a broken heart and with mine came the tightness in the chest, stomach, you name it.
history: Hey. My heart hurts from a broken relationship... That's too bad. A broken heart is a metaphor, but it can refer to physical pain or stress. That's interesting. What else do you know about broken hearts? It's a concept that's thought to be universal. Many cultures use the same words to describe it. Ah, OK. Is there anything physically happening when we feel a broken heart? Yes, there's a neurological process that may overstimulate the vagus nerve, which causes pain, nausea, or chest tightness. Yeah, that sounds like a broken heart.
knowledge: The neurological process involved in the perception of heartache is not known, but is thought to involve the anterior cingulate cortex of the brain, which during stress may overstimulate the vagus nerve causing pain, nausea or muscle tightness in the chest.
