Extended Data Fig. 3: Dissimilarity of evoked and ongoing assemblies is seen also in deep cortical layers.
From: Awake perception is associated with dedicated neuronal assemblies in the cerebral cortex
a, Pearsons’s correlation matrix averaged across 11 mice for the assemblies evoked by sounds in the upper layers of auditory cortex (180–250 um below cortical surface). b, The same as in a, in deep layers (450–600 um below the cortical surface) averaged across 6 mice. c, Top left: average size (number of neurons) of neuronal assemblies in superficial (11 mice) and deep layers (6 mice). Bottom left: average size of neuronal assemblies in % of all neurons in the FOV in superficial and deep layers (p = 0.005, p = 0.02, Wilcoxon rank sum test). Right: sound evoked responses reproducibility in superficial layers is higher than in the infragranular layers (p = 0.0002, Wilcoxon rank sum test). For all tests in c, n = 11 mice for superficial, and n = 6 mice for deep. d, Dissimilarity of sound-evoked and spontaneous patterns for all sounds and sessions in deep layers. Statistics across sessions are given on the right-hand-side histograms (p = 0.03, p = 0.03, Paired Wilcoxon Signed Rank Test, n = 6 mice). (Repro., Reproducibility; Sim., Similarity; Spont, spontaneous; Sup., Superficial; *,**,*** indicate p < 0.05, p < 0.01, p < 0.001 respectively). 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.
