MEG evidence for two types of target-specific brain responses: sustained activation of sensory processes, and access to an additional late processing stage. a Temporal generalization matrices for target (upper panel) and non-target (lower panel) stimuli averaged across inter-target lags. Gray areas correspond to below chance classification performance. Dashed arrows represent selected training time depicted in b. b Classification performance as a function of time for classifiers trained at 170 and 370 ms. Results from signed rank tests comparing classification performance to chance are represented by the thick line below the x axis. Signed rank tests comparing target and non-target conditions are represented by areas filled with red, darker colors representing lower P-values. FDR correction for multiple comparisons was applied across specific training times (120–370 ms), testing times and conditions. c Source localization of activation patterns computed from the support vector machine (SVM) weights (see method) indicating the location of the most informative activity for each stimulus category; 200–250 ms and 350–400 ms averaged training times are represented. For display purposes, data points were smoothed using a moving average with a window of three samples
