In the present study,we demonstrated that forward acoustic masking can boost,rather than suppress,the auditory brainstem response (ABR) in rats treated with a high dose of sodium salicylate (NaSal),a tinnitus inducer.We first carried out this experiment under two conditions:(1) the forward masker and the probe were presented to both ears (diotic paradigm);(2) the forward masker was presented to one ear and the probe to the other ear (dichotic paradigm).We found that only when the stimuli were presented using the diotic,rather than the dichotic,paradigm could forward acoustic masking enhance the ABR in the rat treated with NaSal (300 mg/kg).
