Hate in the Brain


I googled hatred because I had no idea what to write about for my third blog. After I scrolled through the several definitions I found an aritcle from Scientific American about the neurological connection between love and hate. It turns out that after some preliminary research into the origin of hatred in the brain, researchers had found a connection to the origin of Love.

frontal cortex

Researchers wanted to find the neurological origination of hatred. To achieve this they performed Functional magnetic resonance imaging (fMRI) tests on seventeen adults to see where hatred appeared.  The brains of these participants were scanned while they looked at a person that they said they hated. In all of them the frontal cortex was where the hatred originated with parts of the medial frontal gyrus, the right putamen, the premotor cortex, and the medial insula being activated.

Unsurprisingly parts of this wide range of places are involved in activating agressive behavior. However the actual feelings of aggression themselves came from different parts of the brain. Other noteworthy feelings that didn’t originate in the same place are anger, danger and fear.

The most surprising aspect of this research however was that the areas of the putamen and insula that were activated by the picture of someone that the subjects hate, are also activated by love. This surprising discovery may explain why love and hate are so close to each other and why we as humans can experience both emotions in regards to someone or something.

This research is still preliminary and it does not prove that love and hate are connected in the brain, but it does raise some interesting questions about their relationship. Does this explain the phrase love/hate relationship? Could this be the reason why these two powerful emotions seem to have such a close relationship?
