Regional cerebral blood flow (rCBF), a parameter of neuronal activity in the brain, was measured by the 133Xe inhalation method in 43 patients undergoing stereotactic thalamotomy. A postoperative flow reduction of about 2% in the operated hemisphere was found, persisting in further measurements performed after a year. There was no consistent change in the pattern of regional flow distribution. The results indicate a diminished level of activity in the hemisphere subjected to thalamotomy, but the change could not be linked to any specific area or function.
局部脑血流量（rCBF）是大脑神经元活动的一个参数，通过吸入133Xe的方法对43例接受立体定向丘脑切开术的患者进行了测量。发现手术侧半球术后血流量减少约2%，在一年后进行的进一步测量中持续存在。局部血流分布模式没有一致的变化。结果表明，接受丘脑切开术的半球活动水平降低，但这种变化与任何特定区域或功能均无关联。
