The relationship between the human mind and body has been a subject that has challenged great thinkers for millennia, including the philosophers Aristotle and Descartes. The answer, however, appears to reside in the very structure of the brain.
Researchers said on Wednesday they have discovered that parts of the brain region called the motor cortex that govern body movement are connected with a network involved in thinking, planning, mental arousal, pain, and control of internal organs, as well as functions such as blood pressure and heart rate.
The researchers called this system the somato-cognitive action network, or SCAN, and documented its connections to brain regions known to help set goals and plan actions. "Since this system, the SCAN, seems to integrate abstract plans-thoughts-motivations with actual movements and physiology, it provides additional neuroanatomical explanation for why 'the body' and 'the mind' aren't separate or separable," Dosenbach added.
