Fig. 5.

Average nociceptive and horizontal locomotor activity scores of unilateral Ce sham and unilateral Ce lesion rats treated with systemic saline in Experiment 1. Rating scale nociceptive scores are shown in A, flinch nociceptive scores are shown in B, and horizontal locomotor activity scores are shown in C. Error bars indicate SEM. Saline control data collected in Experiment 1 (see Figs. 3, 4) are presented in the samefigure to illustrate clearly that a unilateral Ce lesion did not affect baseline nociceptive responses when formalin was delivered to the hindpaw ipsilateral to the lesion.
