Fig. 9. Patterns of pinch receptive field (RF) expansion outside the area of injury in 11 high threshold (HT) neurons and 29 wide dynamic range (WDR) neurons after an incision in a mechanically insensitive area of the cell RF. The shaded areas of the rat hind paw depict the pinch RF before an incision (  dark line ) and the hatched zones mark the expansion of the pinch RF after an incision.
