Does "love" legitimately exist or is it simply just a chemical reaction in the brain? If the latter is true, does that mean anger, sadness, happiness, and so on are merely chemical reactions as well and nothing more? After reading about a study where scientists cut off the oxytocin receptors in rats, they were no longer rewarded (dopamine) for being around their female counterparts. The rats prior to having their receptors cut off were strictly monogamous, afterwards however, they were none other than polygamous creatures. Now can a similar concept be applied to our emotions? Cut off some sort of receptor and just like that x emotion is nonexistent.
