The rate at which isotopes descend from the cisterna magna to the lumbar subarachnoid space is highly variable. In monkeys, with and without previous lumbar puncture, transit time was measured. In animals with a previous lumbar puncture, transit times were 10 to 120 minutes; in monkeys without a previous lumbar puncture, transit times were 120 to 180 minutes. In experimental studies of cerebrospinal fluid circulation, the effect of lumbar puncture must be controlled.
同位素从枕大池下降至腰段蛛网膜下腔的速率变化很大。对有或没有预先进行腰椎穿刺的猴子测量了转运时间。在预先进行过腰椎穿刺的动物中，转运时间为10至120分钟；在未预先进行腰椎穿刺的猴子中，转运时间为120至180分钟。在脑脊液循环的实验研究中，必须控制腰椎穿刺的影响。
