Study Points to Sixth Sense in Humans

Ben Sullivan writes "St. Louis researchers say there's something to the notion of a 'sixth sense' in humans. A part of the brain known as the cingulate cortex, they've found, likely combines multiple, sometimes unconscious data streams to come to conclusions and send warning signals to the conscious mind. Example: Aboriginal tribesmen somehow sensed the impending danger of December's tsunami in time to flee to higher ground before the first sign of water."
