Demonstrated the cyclical nature of sound perception

A new research proves that the brain samples rhythmically the sensory information that gets to our ears

How do we perceive the sounds? With oscillations that reflect the rhythms of our attention. This was demonstrated by a study published in "Current Biology", entitled "Auditory Sensitivity and Decision Criteria Oscillate at Different Frequencies Separately for the Two Ears", which provided new key evidence of the cyclical nature of perception.

The research is the result of an Italian-Australian collaboration involving David Alais and Johahn Leung of the Department of Psychology and Medical Sciences at Sydney University, David Burr of the Department of Neuroscience at the University of Florence and Maria Concetta Morrone and Tam Ho from the Department of Translational Research at the University of Pisa.
