The local tissue PO2 in the brain cortex and in the spinal cord of rats was examined with ultramicroelectrodes. In the spinal cord the PO2 was highest in white matter, intermediate in dorsal horn gray matter, and lowest in the ventral horn gray matter. In the gray matter of the cord, as well as in the brain, the PO2 at a fixed locus was found normally to oscillate. CO2 responses were more brisk in the cord than in the brain while the responses to hypoxia were similar. Therefore, it appears that the physiological regulation of blood flow in the spinal cord is qualitatively similar to that of the brain.
用超微电极检测了大鼠大脑皮层和脊髓的局部组织氧分压。在脊髓中，氧分压在白质中最高，在背角灰质中居中，而在腹角灰质中最低。在脊髓灰质以及大脑中，发现固定位点的氧分压通常会发生振荡。二氧化碳反应在脊髓中比在大脑中更活跃，而对缺氧的反应则相似。因此，看来脊髓中血流的生理调节在性质上与大脑相似。
