Figure 4

Population data showing the percentage of neurons that fell into different categories of bandwidth change of FLRF. BW₁₀, BW₂₀, and BW₃₀ are the FLRF bandwidth at 10 dB, 20 dB, and 30 dB above MT, respectively. The changes of bandwidth were assigned into three categories: narrowed, widened, and unchanged. Row 1 shows the data of 28 neurons whose FLRFs were determined at five levels of masker conditions, and row 2 shows data of 14 neurons whose FLRFs were determined at four level of masker conditions. The relationships among different masker levels are the following: a < b < c < d < e; a’ < b’ < c’ < d’.
