TI  - Monaural and dichotic forward masking in the dolphin's auditory system.

AB  - Short-latency auditory-evoked potentials (AEPs) were recorded non-invasively in 
      the bottlenose dolphin Tursiops truncatus. The stimuli were two sound clicks that 
      were played either monaurally (both clicks to one and the same acoustic window) 
      or dichotically (the leading stimulus (masker) to one acoustic window and the 
      delayed stimulus (test) to the other window). The ratio of the levels of the two 
      stimuli was 0, 10, or 20 dB (at 10 and 20 dB, the leading stimulus was of a 
      higher level). The inter-stimulus intervals (ISIs) varied from 0.15 to 10 ms. The 
      test response magnitude was assessed by correlation analysis as a percentage of 
      the control (non-masked) response. At monaural stimulation, the test response was 
      of a constant magnitude (5-6% of the control) at ISIs of 0.15-0.3 ms and 
      recovered at longer ISIs. At dichotic stimulation, the deepest suppression of the 
      test response occurred at ISIs of 0.5-0.7 ms. The response was slightly 
      suppressed at short ISIs (0.15-0.3 ms) and recovered at ISIs longer than 
      0.5-0.7 ms. The relation of parameters of the forward masking to echolocation in 
      dolphins is discussed.
