The middle portion of the prefrontal area, the part damaged in Barbara, coordinates an astonishing number of essential skills, including regulating the body, attuning to othe

Clusters of these wandering cells then start to gather at one end of the spinal cord, ultimately to become the skull-encased brain. But other neural tissue becomes intricately woven with our musculature, our skin, our heart, our lungs, and our intestines. Some of these neural extensions form part of the autonomic nervous system, which keeps the bod
