To quantify the strength of this fundamental-period encoding, selected segments of the response histograms were autocorrelated, rectified, and fitted with the best-fitting sinusoid of the fundamental frequency. The magnitude of this best-fitting sinusoid was taken as the magnitude of synchronization. In most cases, it was found that the \u2018\u2018lower-SR\u2019\u2019 fibers (those with spontaneous discharge rates &amp;lt;20\/s) encoded the fundamental periodicity more strongly and more robustly than did the \u2018\u2018high-SR\u2019\u2019 fibers (those with spontaneous discharge rates &amp;gt;20\/s). When either a single strong spectral peak or a relatively \u2018\u2018flat\u2019\u2019 spectrum excited a fiber, it showed poor synchronization to the fundamental period, regardless of its spontaneous-rate class. Judging from a few examples, the glottal-pulse synchronization appears to be intensity dependent, with the relative performance of the high-SR fibers improving at lower intensities. A conceptual model is given which accounts for the general characteristics of the data.<\/jats:p>","DOI":"10.1121\/1.401422","type":"journal-article","created":{"date-parts":[[2005,10,13]],"date-time":"2005-10-13T20:29:19Z","timestamp":1129235359000},"page":"3140-3148","update-policy":"http:\/\/dx.doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":7,"title":["Responses of \u2018\u2018lower-spontaneous-rate\u2019\u2019 auditory-nerve fibers to speech syllables presented in noise.
