The maskers were either cathodic-first symmetric biphasic, pseudomonophasic (i.e., with a second anodic phase longer and lower in amplitude than the first phase), or \u201cdelayed pseudomonophasic\u201d (identical to pseudomonophasic but with an inter-phase gap) stimuli. In experiment 1, forward-masking patterns for monopolar maskers were obtained by keeping each masker fixed on a middle electrode of the array and measuring the masked thresholds of a monopolar signal presented on several other electrodes. The results were very variable, and no difference between pulse shapes was found. In experiment 2, six maskers were used in a wide bipolar (bipolar+9) configuration: the same three pulse shapes as in experiment 1, either cathodic-first relative to the most apical or relative to the most basal electrode of the bipolar channel. The pseudomonophasic masker showed a stronger excitation proximal to the electrode of the bipolar pair for which the short, high-amplitude phase was anodic. However, no difference was obtained with the symmetric and, more surprisingly, with the delayed pseudomonophasic maskers. Implications for cochlear implant design are discussed.<\/jats:p>","DOI":"10.1121\/1.3257231","type":"journal-article","created":{"date-parts":[[2010,1,6]],"date-time":"2010-01-06T10:40:28Z","timestamp":1262774428000},"page":"326-338","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":32,"title":["Forward-masking patterns produced by symmetric and asymmetric pulse shapes in electric hearing"],"prefix":"10.1121","volume":"127","author":[{"given":"Olivier","family":"Macherey","sequence":"first","affiliation":[{"name":"K.U.
