A Brazilian man's compulsion for philanthropy resulted from brain injury, and sheds light on neurological component that compels us to give.
"The history of neuroscience is littered with patients whose behavior changed in bizarre ways after they suffered brain damage. Some people could no longer recognize animals, or couldn’t speak but could still sing. For neuroscientists, these cases offer opportunities: by studying how people’s behaviors change after brain injuries, they gain insight into what role the injured areas play in everyday tasks. And so it was with João—researchers hoped that his compulsive giving could shed light on normal generosity, helping them understand why human beings give and why, biologically, giving feels good. This work does raise uncomfortable questions, though. We normally think of generosity as pure and noble—evidence of the soul, not evidence of brain damage. But what if giving is largely a reflex or an instinct or even, sometimes, a sign of mental derangement?" -- Sam Kean, the Atlantic
