Figure 5. Relative contribution of added and shifted spikes to response peak depends on the pattern of background activity.
Firing rate changes in episodes in which response peak was composed of shifted spikes (n=7, left column), added spikes (n=7, middle column) and a combination of shifted and added spikes (n=4, right column). Responses to injection of fluctuating noise with aEPSCs, noise only, and their difference. Averaged membrane potential traces are superimposed on the respective histograms. Dashed vertical lines show onset of aEPSCs.
