Fig. 4: Analysis of representational formats using the BL-NET network.

A Representational consistency at each time interval of the BL-NET network was computed by correlating representations formed at successive time points. Each curve represents one layer of the network, color-coded from early (blue) to deep layers (pink). B Two-dimensional projections of the first and last time point of each layer in the BL-NET network showing greater representational distances in the first layer than in all other layers. C Pairwise correlations of RSMs corresponding to the first (left) and last (right) time points in each layer of BL-NET. D Within-category, between-category and within-category vs. between-category correlations (i.e., Category Cluster Index, CCI) for each layer of BL-NET (last time point). E RSMs and corresponding MDS projections for the last time point of all BL-NET layers. In the MDS plots, items are color-coded according to category. F Correlations between BL-NET RSMs (last time point in each layer) and neural RSMs during encoding in VVS. Outlined clusters indicate time-frequency periods where correlation values are significantly higher than zero at the group level (two-sided t-tests, Bonferroni corrected for 7 layers). G Same analysis as in F for the PFC. H Same analysis as in F for the maintenance period in the VVS (top) and PFC (bottom). In the VVS, BL-NET representations in layers 4, 5, and 6 matched representations in the theta/alpha frequency range (3-14 Hz) prior to the probe. In the PFC, BL-NET representations in the last layer matched representations in the beta band (16–29 Hz) following presentation of the retro-cue. Color scale of all t-maps in F, G and H is indicated at the right of each panel. Source data are provided as a Source Data file. ***p < 0.001; *p < 0.05.
