The First Light Picture and Human Portrait Ever Taken [Oct,Nov 1839]
Robert Cornelius, self-portrait, Oct. or Nov. 1839, approximate quarter plate daguerreotype which is a procedure invented in 1839 using silver on a copper plate. The back reads, “The first light picture ever taken.” This self-portrait is the first photographic portrait image of a human ever produced.
“Functional magnetic resonance imaging scans showed that the experience of being snubbed lit up a part of the subjects’ brains (the dorsal anterior cingulate cortex) that also lights up when the body feels physical pain.
I asked Eisenberger why, if the same part of our brain processes social insult and bodily injury, we don’t confuse the two. She explained that physical harm simultaneously lights up another neural region as well, one whose job is to locate the ache—on an arm or leg, inside the body, and so on. What the dorsal anterior cingulate cortex registers is the emotional fact that pain is distressing, be it social or physical. She calls this the “affective component” of pain. In operations performed to relieve chronic pain, doctors have lesioned, or disabled, the dorsal anterior cingulate cortex. After the surgery, the patients report that they can still sense where the trouble comes from, but, they add, it just doesn’t bother them anymore.”
