A group of neurons responsible for focusing on people's facial expressions and intent once being misplaced, as Science Mag reports, were recently discovered in the brains of rats. Neurons in the region called the caudate nucleus that would be responsible for deciding what a person is trying to convey by smiling or frowning appear to have the opposite function.
For instance, if someone smiles, the caudate nucleus would be fired up and the electrical brain activity would increase to test the owner's intent. Yet, the new findings suggest that the neurons are no longer firing in response to the owner's intentions as they once did. In that way, this discrepancy occurs in the brain not only with a vision for self but also the relation of self to another.
The discovery overturns the belief that an owner's facial expression, intent, and orientation is displayed by himself, even unconsciously, the report states.
