1. A system for modifying neural transmission patterns between a first neural structure and a second neural structure, the system comprising: a transducer arrangement configured and arranged to produce sound for stimulating the first neural structure and the second neural structure; and a control circuit configured and arranged to control of characteristics of sound waves at the first target neural structure with respect to characteristics of sound waves at the second target neural structure for modifying the neural transmission patterns between a first neural structure and a second neural structure.
