Neuroscientists believe they have discovered the underpinnings of the phenomenon known as déjà vu. This happens when an individual gets the sensation an experience has already occurred. Unfortunately for one scientist, finding the answer has proven anything but rewarding. Dr. Stanley Whittle explains, “Déjà vu has always fascinated me. Not only the strange word and those even stranger dohickeys over two of the letters, but all the other really fun brain stuff. Essentially, it involves the conflict-checking region of the frontal lobes, but once this region is over-stimulated, well, it’s like biting the inside of your mouth. It keeps being triggered. Didn’t you just ask me that?”
