I had quite some material to dig= est. For dynamic stimuli (FM), there seems to be a bias for rising frequenc= y and this could be explained at the level of basilar membrane. I am intere= sted to know whether this bias is preset for static stimuli? i.e., is a hig= h frequency tone easy to detect in a sequence as compared to low frequency = tones? Is the frequency discrimination better when the comparison tone is o= f higher frequency to the reference tone compared to the condition where th= e comparison tone is of lower frequency?
