Electrical stimulation is applied to the inferior colliculus or colliculi (IC), in order to diminish tinnitus by revising auditory pathway neuronal activity. This intervention diminishes tinnitus and treats other neurological and otological disorders. The locations and methods of electrode placement and anchoring and the structure of the electrodes are an advance over prior treatments. Other treatment locations in the nearby region of the IC, including the superior colliculi (SC) and Peri-aqueductal gray (PAG), provide treatments for other disorders and symptoms such as partial hearing loss and pain. The IC is a unique choice for the treatment of tinnitus and other disorders because an electrode placed in that region enables minimal invasiveness. The anchoring location also uniquely minimizes invasiveness by providing the option of residing in the meninges instead of the brain tissue. The shape of the electrode and its anchoring process uniquely match the brain's anatomy in order to provide greater specificity in diagnosis and treatment. Stimulation of areas near the IC, particularly the superior colliculus and peri-aqueductal gray, can be used to treat various neurological disorders. Customized feedback from the implantable system enables the creation of customized treatment programs.
