Periodicity-sieve analysis quantifies which pitch components dominate cochlear nucleus firing to mixed vowels

Evidence

We applied a “periodicity-sieve” analysis to the correlograms to estimate the dominant period(s) in the inter-spike-interval statistics (e.g., Larsen et al. 2008 ); yielding template-contrast functions . To assess the statistical significance of peaks in the template-contrast function we used a bootstrap technique (permutation analysis; 1000 replications: p < 0.01 considered significant). Based on the template-contrast functions in response to double vowels, we computed the “periodicity-tagged” firing rate for each vowel of the mixture (similar to that proposed by Keilson et al. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5037 (#expands, via linked claim)
