Ipsilateral efferent stimulation elicits fast and slow excitation. (a) Irregularly-discharging afferent showing the onset of ipsilateral brainstem stimulation (333 shocks/s, green bar). (b) Corresponding continuous histogram showing changes in afferent firing rates during three successive ipsilateral stimulation trials (333/s for 5 s delivered every 60 s, green boxes). Average response histogram shown to the right of arrow. (c) Average response histograms to ipsilateral efferent stimulation (background subtracted) in five units with different CV* values. Histograms are plotted as a displacement from background (dashed line). Number of trials used to construct mean histograms indicated in each trace. Binning in panels (b,c) is 500 ms.
