Sensors became category-discriminative in two waves. (A) The first time, relative to stimulus onset, when the relationship between ERF amplitude and category membership became significant by ANOVA (significance threshold set at 95% of peak-level (across all sensors and all time) log10(p) of 100 shuffles) at each of 275 sensors. Many occipital and temporal sensors first became predictive of Si category between 90 and 230 ms post stimulus onset, followed by some parietal and frontal sensors ranging from 330–550 ms post stimulus onset. Open circles indicate the sensors that never reached 95% peak-level. (B) Histogram of how many sensors first became significantly discriminative at each time following stimulus presentation.
