Signal to noise constraints on maximum length sequence auditory brain stem responses.

abstract：OBJECTIVES:It is well established that catastrophic misinterpretations and fear are involved in the suffering and disability of patients with chronic pain. This study investigated whether similar processes explain suffering and disability in patients with chronic tinnitus. We hypothesized that patients who catastrophic...
