Studies in a bottlenose dolphin Tursiops truncatus measured the time of release of short-latency auditory evoked potentials (auditory brainstem responses, ABR) from forward masking during contact sound stimulation with short tonal bursts both when the sources of the conditioning and test signals were positioned on one side of the head (unilateral stimulation) and when the sources were positioned on different sides of the head (bilateral stimulation). In both variants of stimulation, significant suppression of the testing ABR was observed at interstimulus delays of less than 1 msec, with almost complete recovery of the test response (release from masking) at delays of about 5 msec. These results suggest that effects of forward masking develop predominantly in binaural auditory structures, where the afferent inputs from the two cochleas interact.
