Figure 4. Stimulus-level and feature-level information during perception versus memory. A, The relative strength of perceptual versus mnemonic stimulus information differed between OTC and LPC (F(1,32) = 113.6, p < 0.001). Across both experiments, OTC contained stronger stimulus information during perception than during memory (F(1,32) = 28.0, p < 0.001), whereas LPC contained stronger stimulus information during memory than during perception (F(1,32) = 40.8, p < 0.001). B, Across both experiments, the relative strength of perceptual versus mnemonic feature information also differed between OTC and LPC (F(1,32) = 29.27, p < 0.001). OTC contained marginally stronger feature information during perception than during memory (F(1,32) = 3.93, p = 0.056), whereas LPC contained stronger feature information during memory than during perception (F(1,32) = 11.65, p = 0.002). Legend is the same as in A. Error bars indicate mean ± SEM across 17 subjects. C, Stimulus information during perception and memory plotted separately for each ROI, collapsed across experiment. D, Color and object feature information during perception and memory plotted separately for each ROI, collapsed across experiment. Error bars indicate mean ± SEM across 34 subjects. For results of t tests assessing perceptual and mnemonic feature information for each ROI separately, see Table 1.
