Extended Data Fig. 4: Ongoing assemblies during stimulation are also dissimilar to evoked responses.
From: Awake perception is associated with dedicated neuronal assemblies in the cerebral cortex
a, For an example recording session, Pearson’s correlation matrix between spontaneous assemblies sorted by hierarchical clustering and single trial sound response patterns. Spontaneous assemblies detected during stimulation sessions in between evoked responses are clustered in the small white rectangle. Their similarity with evoked and spontaneous pre-stimulation assemblies (big white rectangle) are within orange and red rectangles, respectively. b, Dissimilarity of sound-evoked and spontaneous patterns (SpontStim) detected during stimulation (reproducibility on abscissa and similarity on ordinate). Statistics across sessions are given on the right-hand-side histograms (p = 0.001). c, Similarity of ongoing assemblies observed during the pre-stimulation and stimulation epochs. (p = 0.41, Paired Wilcoxon Signed Rank Test, n = 11 mice in b and c). (NS, not significant; Repro., Reproducibility; Sim., Similarity; Spont, spontaneous; *** indicates p < 0.001). For all box-and-whiskers plots, the red mark indicates the median, and the bottom and top edges of the box indicate the 25th and 75th percentiles, respectively. The whiskers extend to the most extreme data points. All tests are two-sided.
