The part of the brain that recognizes new scenery and
   backgrounds - like a forest, or a field, or static places as a
   backdrop where nothing is happening, is the same place that is
   activated when people are being sarcastic. Yeah, right, so
   that's where context comes from? The backgrounds of where the
   words change? Well, that's my interpretation of what it means
   anyway. -Ken, on Parahippocampal Place Area
