Fig. 6: Specificity of evoked patterns relies on a subset of neurons in the awake state.
From: Awake perception is associated with dedicated neuronal assemblies in the cerebral cortex
a, Top: plot of the probability of responding to any sound versus the probability of being recruited in an ongoing event for 6,310 neurons in 11 mice. The color code indicates whether the neuron prefers ongoing (blue) or evoked (magenta) events or nonspecifically participates in both types of events (cyan, boundaries: ±1 m.a.d. of the probability difference). Middle: for a sample session, Pearson’s correlation matrix was computed with all available neurons. Bottom: average sound and spontaneous event cluster reproducibility. b, Same as a but correlation matrix and reproducibility (mean correlation across assemblies of the same spontaneous cluster or of the same sound) are calculated with nonspecific neurons only (67%). c, Same as a but for sound responsive neurons only (15%). d, Same as a but only for neurons preferring ongoing events (18%). e, Same as a but for all except nonspecific neurons (33%). Post, poststimulation; Pre, before stimulation; prob., probability; Resp, responsive; Spont, spontaneous. *P < 0.05, **P < 0.01, ***P < 0.001 respectively. For box-and-whisker 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 indicate the most extreme non-outlier data points. Red crosses are outliers. b–e: P = 0.002/0.001/0.001; P = 0.001/0.02/0.001, P = 0.001/0.001/0.001, P = 0.001/0.001/0.001; paired Wilcoxon’s signed-rank test (n = 11 mice). All tests are two sided.
