Classification performance over various time intervals. Classification performance for a linear classifier on test data as a function of the number of neurons in ensembles #1 (green), #2 (blue), and #3 (red) and combination (neurons pooled over all ensembles; dotted black). Each column shows roles of stimulus perception, stimulus retention, motor selection, and stimulus comparison. Each row shows performances over 2 ms, 4 ms, 8 ms, 10 ms, 50 ms, 100 ms, and 200 ms time intervals on a logarithmic scale. Error bars show the SEM. Dashed lines show chance levels (= 50%).
