‘The world today doesn’t make sense, so why should I paint pictures that do?’ –Picasso
By asking a group of older adults to analyze videos of other people conversing — some talking truthfully, some insincerely — a group of scientists at the University of California, San Francisco has determined which areas of the brain govern a person’s ability to detect sarcasm and lies.
Some of the adults in the group were healthy, but many of the test subjects had neurodegenerative diseases that cause certain parts of the brain to deteriorate. The UCSF team mapped their brains using magnetic resonance imaging, MRI, which showed associations between the deteriorations of particular parts of the brain and the inability to detect insincere speech.
