The table illustrates the correlations between von Frey-induced withdrawal responses and paw palpation-induced Fos positive cells (secondary hyperalgesia; Left panel) and between gastrocnemius compression peak forces and gastrocnemius compression-induced Fos positive cells (primary hyperalgesia; Right panel) in the ipsilateral superficial, intermediate and deep dorsal horn.
