Synchrony, oscillations, and phase relationships in collective neuronal activity: A highly comparative overview of methods
Fig 6
Visualizing collective dynamic coordination in rat auditory cortex spiking activity through the lens of the highly comparative approach.
A: A dataset comprising 14 recordings is visualized through the highly comparative description, highlighting nonstationarities, pseudo-rhythmic patterns, and recording-wise idiosyncrasies. Each row corresponds to a MSTM, each column to a 30 s time window; values are z-scored across windows. MSTMs are ordered according to the outcome of an average linkage hierarchical clustering procedure over MSTMs. Time windows are ordered chronologically and recordings are concatenated and indicated by the color-coded labels on top, using the same identifiers as in the original dataset [84]. Gray cells indicate time windows where the FOOOF spectral peak parameter was below the significance threshold, hence the corresponding parameters were not assigned. B: The same data shown in A is replotted by ordering time windows according to the outcome of an average linkage hierarchical clustering procedure over time windows as in Fig 7A. Vertical lines on top color-code for recording session as in (A); their length codes for chronological order within each session. In both (A) and (B), values greater than , where SZ indicates a generic MSTM value after z-scoring and the maximum value is taken over MSTMs and time windows, are clipped to that value for improved visualization. Corresponding results for the mouse and monkey datasets are shown in S7 Fig.
