功能性磁共振成像(fMRI)技术使用血氧水平依赖(BOLD)信号来表示离散的、有神经活动的区域。尽管已有大量关于人类脑的fMRI研究,目前很少有研究者使用fMRI技术研究人类脊髓的神经活动。2012年Brooks等通过单次fMRI扫描,来评估C6和C8脊神经节段支配区域给予伤害性刺激对脊髓活动的影响。Brooks等发现,在伤害性刺激作用下,脊髓背角BOLD信号具有偏侧性,但不能分辨刺激不同脊神经节段
Functional Magnetic Resonance Imaging (fMRI) technology uses a blood oxygen level dependent (BOLD) signal to represent discrete, neuro-active regions. Although there are a large number of fMRI studies on human brain, few researchers use fMRI to study the neural activity of human spinal cord at present. In 2012, Brooks et al evaluated the effect of nociceptive stimuli on spinal cord activity by a single fMRI scan to evaluate the dominance of C6 and C8 spinal nerve segments. Brooks et al found that under nociceptive stimulation, the BOLD signal in the dorsal horn of the spinal cord possesses laterality but can not distinguish between stimulation of different spinal nerve segments
