Response and receptive field properties were determined for 24 spinal neurons backfired from midbrain or midbrain-thalamus in the anesthetized monkey. Recording sites were located in laminae I (11 cells), IV (6), V (6) and VI (1) in the lumbosacral spinal cord. The mean axonal conduction velocity of cells projecting to midbrain was significantly less than that of cells projecting to midbrain-thalamus. Cells backfired only from midbrain had complex excitatory receptive fields whereas those projecting to midbrain-thalamus had excitatory receptive fields confined to a single limb. Cells in both populations had complex inhibitory receptive fields.
在麻醉的猴子中，测定了24个从中脑或中脑 - 丘脑逆向激活的脊髓神经元的反应和感受野特性。记录部位位于腰骶脊髓的I层（11个细胞）、IV层（6个）、V层（6个）和VI层（1个）。投射到中脑的细胞的平均轴突传导速度明显低于投射到中脑 - 丘脑的细胞。仅从中脑逆向激活的细胞具有复杂的兴奋性感受野，而投射到中脑 - 丘脑的细胞的兴奋性感受野局限于单个肢体。这两类细胞均具有复杂的抑制性感受野。
