Other findings included an abnormal link in tinnitus patients between the auditory system and the limbic system - the brain wiring responsible for emotions - which may explain why tinnitus can be so emotionally crippling.
Dr Alan Lockwood, of the State University of New York at Buffalo, who headed the study, said: "Changes in the brain occur following many forms of neural injury ... These changes may be responsible for symptoms such as phantom limb pain, a syndrome in which amputees feel excruciating pain that seems to originate in the missing limb. We believe that tinnitus may be the auditory counterpart to phantom limb pain."Reuse content
