Figure 4.

Figure 4

Cells with α-range OF exhibited elevated burst firing and a unique form of burstiness. A) A segment of raw data from an α-range OF cell with raster plot above indicating times of burst firing (blue lines). A sub-panel below shows a time-expanded view of raw spike data from an exemplar burst to illustrate the accelerating firing rate during the burst accompanied by progressively decrementing action potentials. B) Marked modulations in the cell’s autocorrelation (top) and significant spectral peaks in the α and β frequency ranges of the power spectrum (bottom) are consistent with strong OF. C) Peri-burst rasters from the same cell aligned to the onset of the burst (top) and the mean peri-burst frequency of firing across all bursts (bottom). Otherwise, the figure follows the conventions outlined for Fig. 1. Note the absence of a pre-burst notch in firing rate, the accelerating firing rate during the burst, and abrupt cessation of firing with burst offset.
