Synchrony, oscillations, and phase relationships in collective neuronal activity: A highly comparative overview of methods
Fig 7
Auditory cortex spiking activity exhibits structured variability that is distinctive of each recording.
A: Dendrogram showing the distances between time windows as a hierarchical cluster tree. B: Similarity matrix showing the Spearman correlation coefficient between any pair of time windows. Vertical lines on top color-code for recording session and their length codes for chronological order within each session as in Fig 6B. C: MDS representation of the distance matrix obtained from the values shown in B by taking D = 1 − ρ. Each circle represents a time window, color-coded as in Fig 6. D: Silhouette plot showing for each time window, its mean value in the dataset (red vertical line), and the
significance threshold (gray dashed vertical line). Corresponding results for the mouse and monkey datasets are shown in S8 Fig.
