Alfred Tomatis was a Medical Doctor (ENT) who devoted his life to studying the close relationship between the voice, the brain and the ear. His work has had a revolutionary impact on how an individual communicates with himself and others. A pioneer in the field of cognitive science, Alfred Tomatis leaves an indelible mark both with its discoveries and by his extraordinary personality. Today we measure the extent of his inheritance in the light of recent research on brain plasticity. In 2016, the famous neurologist Norman Doidge gives him a tribute in his latest book ""The Brain's Way of Healing"". Let's go back in time."
