Phase-locked spiketrains integrate both envelope and temporal fine structure cues.
Evidence
A very basic simulation has been performed to check for the potential use of various types of periodicity cues (i.e. TSFperiod , TEperiod or TE × TSFperiod ) with various signals used in the literature. The basic idea was to pass the stimulus through a dynamic compressive gammachirp (the default auditory filter-bank of the Auditory Image Model) (Irino and Patterson 2006 ) and to transform the output waveform into a spiketrain by using a threshold dependent model. This model has a higher probability to spike each time the output is over a threshold value (see Eq. 1 ). Moreover, a reasonable refractory period of 2500 Hz is added to the simulation. The periodicities of the spiketrain are finally extracted with an autocorrelation. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4622 (
