> A team of cognitive neuroscientists at the University of Zurich, has found that ancient Aztec "skull whistles" found in gravesites are able to instill fear in modern people. In their study, published in the journal Communications Psychology, the group recorded the neural and psychological responses of volunteers as they listened to the screams produced by the whistles.

> The volunteers exhibited similar reactions—certain low-level cortical auditory regions of the brain became instantly activated, indicating that they were on high alert. They also found that the volunteers said the sound made them feel frightened and aversive—they wanted it to stop. The researchers also found that the whistle sound tended to confuse the brain, leaving it reeling momentarily. This, they suggest, hints at the possibility that the whistle was used during ceremonies surrounding the dead, possibly as a way to frighten attendees.
