Fig. 3

Box plots showing the difference in the mean FSL (“dMean FSL” in the top row) and the difference in the SD FSL (“dSD FSL” in the bottom row) between responses elicited by the same sound (TL or TH) presented as Odd and Eql and between those elicited by the same sound presented as Std and Eql. Results were obtained when two sounds of a train of stimuli (i.e., TL and TH) were colocalized at c90°. The left, middle, and right columns are results from entire group of neurons, neurons with sustained firing, and neurons with transient firing, respectively. Two sets of data based on responses elicited by TL and TH, respectively, presented at the same probability (i.e., as Odd, Eql, or Std) were combined in making each plot. “*” and “**” indicate the statistical significance at levels of p<0.05 and p<0.005, respectively.
