Figure 8

Plotted in the main panel are the locations of azimuth centroids at 20 and 40 dB above threshold for units where these were defined at both levels. Data points on or near the diagonal indicate a close correspondence between centroids at the two levels. The paucity of data points within the top-left and bottom-right quadrants indicates that centroids rarely shifted from one lateral hemifield to the other with changing level, suggesting that most units maintained at least their basic tuning properties. In the top panel are the centroid locations of those units having centroids at 20 but not 40 dB above threshold. In the right panel are the centroid locations of those units having centroids at 40 but not 20 dB above threshold. There are no data points obscured by the figure legend.
