Tinnitus to the inner ear can cause tinnitus, other apparent causes (e.g., temporomandibular joint dysfunction) are difficult to explain. It may be caused by increased neural activity in the auditory brainstem, where the brain processes sounds, causing some auditory nerve cells to become over-excited. The basis of this theory is that many with tinnitus also have hearing loss.

Even when tinnitus is the primary complaint, audiological evaluation is usually preceded by
Body part as an object than IO pantomimes (despite the prevailing conception that they are simpler), and that BPO involves the right hemisphere as well as the left hemisphere. These results could be extended as an explanation of why apraxic brain damage - usually found in left-hemisphere - leads to BPO production. This may be an indication that apraxic’s utilize their right-hemisphere in lieu of their left-hemisphere damage, and therefore produce more BPO pantomimes. Concepts leading to the exploration and discovery of body part as object pantomimes first began in the late 19th century. Problems in the ability to comprehend or communicate with symbols, asymbolia,
