A: example neurometric functions based on a simulated 2-alternative forced-choice psychophysical paradigm. Horizontal lines indicate criteria for determining threshold (70.7 and 29.3%); rate and synchrony-based functions are distinguished by filled and open circles, respectively. B: distribution of population’s rate-based thresholds. C: distribution of synchrony-based thresholds. X labeled on abscissa in C represents cells with neurometric functions that did not cross above 70.7% or below 29.3% over entire range of tested depths. In both B and C, bold portions of abscissa indicate approximate range of perceptual AM detection thresholds.
