“Neuroscience Explains Why the Grinch Stole Christmas”
Dr. John Cacioppo, a researcher from U of Chicago and his team, use fMRI in thier work surrounding social isolation, connection and evaluative processes. David DiSalvo writes about Cacioppo’s recent work re: neurobiology of emotion, showing that:
…people with an acute sense of social isolation appear to have a reduced response to things that make most people happy, and a heightened response to human conflict. This explains a lot about people who not only seem to wallow in unhappiness, but also seem obsessed with the emotional “drama” of others. (via)
