THE LAMINARY PROJECTION OF ACUPUNCTURE AND NOXIOUS INFORMATION IN THE RAT SPINAL CORD DORSAL HORN / 西安交通大学学报(医学版)

The relative quantitative [~3H]-2-deoxyglucose (2DG)method was used to study the laminary projection of acupuncture and noxious information in the rat spinal cord dorsal horn. The noxious information projected to lamina Ⅰ、Ⅱ、Ⅳ、Ⅴ、Ⅵ and Ⅹ, and the acupuncture information projected to lamina Ⅰ、Ⅱ、Ⅳ and Ⅴ in the spinal cord dorsal horn. The noxious and acupuncture information had overlapping projection areas in the spinal cord. It is in such areas that the two types of information may be interacted on each other and consequently the nociception is modulated at the spinal level.
