ABSTRACT:
A neural prosthetic device for reducing or eliminating the effects of tinnitus is inserted into a tinnitus patient's primary auditory cortex (or thalamus). The prosthetic device includes a stimulation device for outputting processed electrical signals and an electrode arranged in the primary auditory cortex having a plurality of electrical contacts. Each of the plurality of electrical contacts independently outputs electrical discharges in accordance with the electrical signals. In another embodiment, a catheter is inserted into the tinnitus patient's primary auditory cortex or thalamus. The catheter microinfuses drugs which suppress or eliminate abnormal neural activity into disperse geometric locations in the cortex or thalamus, thereby reducing or eliminating the effects of the patient's tinnitus.
