This figure is similar to Fig. 4e,f but with reconstruction variance (termed explained variance in Kobak et al.37) instead of the conventional percentage variance explained. (a) Percent reconstruction variance of the population projection onto the top decision readout. Black lines show the percent variance explained from the original neural data, colored box-whisker plots show the variance explained distribution from 200 surrogate samples (same convention as Fig. 4 e,f; stars denote significantly high variance; upper-tail test). The variance of the decision projection is calculated during the decision epoch (100 ms after the second stimulus onset, until the second stimulus offset). (b) Same as a but for reconstruction variance of the population projection onto the top stimulus readout. The variance of the stimulus projection is calculated during the stimulus epoch (100 ms after first stimulus onset, until the second stimulus onset).
