Response amplitude in different noise levels.

<div><p>A. The response of an exemplar unit (U10) to body images in different noise levels (black: 10%, red: 30%, green: 45%, blue: 60% and magenta: 100%). Here and in all other plots of temporal pattern of the events, responses of units were measured in 1-ms bins and smoothed by convolving with a 30-ms Gaussian kernel. The gray box represents the period of evoked activity used for the further analysis.</p> <p>B. Mean response of the exemplar unit in A (U10) to body images with different levels of ambiguity, during 100 to 300 ms after stimulus onset. Error bars denote s.e.m. across different trials. Stars show the p-values of the t-test between pairs of noise levels (*: P<0.05; **: P<0.01; ***: P<0.001; ****: P<0.0001; *****: P<0.00001). Inset r and P show the correlation coefficient and its p-value for the Pearson correlation analysis between responses and noise levels.</p> <p>C. The response of the exemplar unit (U10) to object images. Conventions as in A.</p> <p>D. Distribution of the body selectivity index (see Methods) for all of the recorded units. Red data point shows the exemplar unit (U10).</p> <p>E. Averaged response of all units to body images with different levels of noise. For normalization, peak response of each unit was measured before smoothing. Then smoothed responses of each unit in different noise levels were normalized to the peak response of that unit. Finally, normalized responses of different units in each noise level were averaged. Shaded area shows s.e.m. across different units. Conventions as in A.</p> <p>F. Mean normalized response of all units to body images in different levels of noise, during 100 to 300 ms after stimulus onset. Error bars here and in other figures denote s.e.m. across different units. Conventions as in B.</p>
