It is widely believed that formation of cerebrospinal fluid (CSF) takes place within the cerebral ventricles--80 to 85% being produced by the choroid plexus and the remaining 15 to 20% being secreted by the lining ependyma. It has also been suggested that CSF is formed within the subarachnoid space. To investigate this possibility. CSF formation was measured in the isolated subarachnoid space of the cat. In 16 animals that underwent 26 steady-state perfusions, the rate of formation of CSF was found to be only 0.00005 +/- 0.00056 (SE) ml/min. It is therefore concluded that little or no CSF is formed in the spinal subarachnoid space of the cat.
人们普遍认为脑脊液（CSF）在脑室中形成——80%至85%由脉络丛产生，其余15%至20%由室管膜衬里分泌。也有人提出脑脊液在蛛网膜下腔形成。为了研究这种可能性，在猫的分离蛛网膜下腔中测量了脑脊液的形成。在16只接受26次稳态灌注的动物中，发现脑脊液的形成速率仅为0.00005±0.00056（标准误）毫升/分钟。因此得出结论，猫的脊髓蛛网膜下腔中很少或几乎不形成脑脊液。
