Figure 4

A) Single unit detected simultaneously on 5 closely-spaced channels recorded from left L7 DRG responding to leg brushing. Waveforms shown color-coded by channel, with label indicating mean peak-to-peak waveform amplitude. Darker waveform is the mean waveform. B) Raster plot of waveforms in (A), showing simultaneity. Grey boxes indicate periods of leg brushing. (C) Estimate of neural source location. Dashed circles represent estimated distance of source from each electrode (colored circles), and their intersection (black circle) is the estimated source. The black line indicates the standard deviation of the estimate. The left plot is a top-down view through the array. The right plot is a side view axially through the DRG. A representative hematoxylin & eosin-stained DRG (from same experiment) is shown to scale in the side-view. The epineurium and some cell bodies are labeled for reference.
