Look, we all love facebook, but it’s hurting both us and our relationships.
Pain in the Brain
Pain consists of two components—the sensory and the affective—and those components reside in distinct regions of the brain. The somatosensory cortices allow us to know where we are injured while the posterior insula tells us how bad it is. The physical experience of pain is what we call the “sensory component.” The “affective component”—provided by the dorsal anterior cingulate cortex (dACC) and the anterior insula—gives us the feeling that the pain is unpleasant.
