Research Provides Important Insight On The Brain-Body Connection (scienceblog.com)

A study conducted by University of Arkansas researchers reveals that neurons in the motor cortex of the brain exhibit an unexpected division of labor, a finding that could help scientists understand how the brain controls the body and provide insight on certain neurological disorders.

The researchers studied the neurons in the motor cortex of rats and found that they fall into two groups: “externally focused” neurons that communicate with and control different parts of the body and “internally focused” neurons that only communicate with each other and don’t send signals to other parts of the body. The researchers also found that when they increased inhibition of neurons in the motor cortex, the externally focused neurons switched to internally focused.
