New Definition of the "Sacculus":

"Loud music stimulates a part of the ear connected to the brain's pleasure centre which controls the body's craving for sex and food. People's response to the thumping beat of pop music is controlled by a tiny organ in the inner ear called the sacculus which till now was thought to have nothing to do with any hearing function. The sacculus normally controls a person's sense of balance but is also sensitive to noises above 90 decibels. When the volume of a sound is turned up it generates vibrations that are picked up by the sacculus, according to Dr. Neil Todd, who led the research team. The distribution of frequencies that are typical in rock concerts and at dance clubs almost seem designed to stimulate the sacculus, Dr. Todd told the New Scientist."
