Its action - The Ear’s Schematics
The Tomatis Method is a technique of sound sensory stimulation. Sound is transmitted on two pathways, the first by bone conduction caused by a vibration in the upper part of the cranium, and the second by aerial conduction passing through the ear’s auricle.
As an effect of the vibration caused by the sounds, these muscles will in turn stimulate the parts of the inner ear known as the cochlea and the vestibule. The cochlea is lined with tiny cells called hair cells, whose purpose is to convert this vibration into electrical stimuli. These stimuli will then feed a vast neural network known as the reticular formation, which controls the overall level of cerebral activity. In other words, the cochlea and vestibule energise the brain. We say that it has a function of 'cortical charging'.
Moreover, the vestibule informs the brain of the tiniest bodily movements and therefore has an effect on rhythm and balance. The coherence of the message that it transmits is thus fundamental. The ear must therefore be effectively stimulated.
