Dynamics of other thalamic neurons firing before gamma onset. A, Peri-gamma burst z-scored firing probability raster plots and average (shaded error bars) firing probability curves for other thalamic neurons with respect to non-sync and sync mPFC gamma burst onset (dashed vertical line), with and without the UP state contribution (UP state removed). The neurons are separated into two subgroups (horizontal black line) based on the significant increase of their firing with respect to gamma bursts, as indicated by the color scale (right): gray: p ≥ 0.05; pink: p < 0.05 (see Materials and Methods). The increase in firing disappears when the influence of the UP state is removed. B, Peri-gamma burst z-scored firing probability raster plots and firing probability curves for the same neurons as in A with respect to HPC gamma burst onset. The increase in firing disappears when the influence of the UP state is removed.
