Spike and burst coding in thalamocortical relay cells
Fig 7
Event Triggering Average (ETA), using a fast-fluctuating input current.
Repeat of the experiment in Fig 6 but now with the input filter (τ = 1 ms) and only for mixed membrane states at −70 mV (top row) and −60 mV (bottom row) as only they produced sufficient spikes and bursts for the analysis. Left column: ETA of the membrane potential 500 ms preceeding single spikes (green) or bursts (blue). Right column: ETA over the input current (mean value substracted and normalized with the L2 norm). The horizontal black line indicates the mean value of the subthreshold membrane potential calculated from the entire trial. Other details as in Fig 6.
