We find that the results could provide invaluable information for basic neuroscience research. For image experiments, we do in vivo brain mapping studies with 18F-FDG (Fluorodeoxyglucose) PET (Positron Emission Tomography) to measure relative cerebral metabolic rate of glucose (rCMRglc) and BOLD (Blood Oxygenation Level Dependent) fMRI (Functional Magnetic Resonance Imaging) to measure hemodynamic response. The results not only show the global somatotopic organization of noxious stimulation on hindquarters in rats, but also find that the activated positions were well correlated with electrophysiological experiments.application/pdf759526 bytesapplication/pdfzh-TW國立臺灣大學醫學工程學研究所微型正子電腦斷層掃描功能性磁振 造影大腦皮質視丘福馬林大鼠microPETfMRIcerebral cortexthalamusformalinrat大鼠腦電位信號分佈與MicroPET功能性影像之相關性研究reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/22393/1/932213E002066.pdf
