Abstract:
Classification of dorsal horn neurons based on cell activity responses to somatic receptive fields stimulation, was compared between anesthetized cats with transected or intact cords. Results showed a significant (P < or = 0.001) difference. In animals with transected cords, dorsal horn neurons responded with less specificity to noxious and innocuous stimulation. The results are consistent with the proposition that loss of supraspinal influences plays a significant role in determining response characteristics of dorsal horn neurons.
