... to electric sources, which led to the discovery of electroreception ( Shackelford, 1941 ) and was later characterized as a ‘field line-tracking’ behavior ( Davis and Hopkins, 1988 ; Hopkins et al., 1997 ; Westby, 1974 ). The experiments were carried out during the summer months, after fish had adapted...

... a single parameter in the stimulus waveform. The finding of waveform distortion sensitivity is relevant because it may contribute to: (a) enhance electroreceptive range in the peripheral ‘electrosensory field’, (b) a better identification of living prey at the ‘foveal electrosensory field’ and (c) detect...

The gain between refuge movement stimuli and fish tracking responses was functionally identical across all sensory conditions. However...
