Gender differences have been noted in neurobehavioral studies. The 133xenon inhalation method for measuring regional cerebral blood flow (rCBF) can contribute to the understanding of the neural basis of gender differences in brain function. Few studies have examined gender differences in rCBF. In studies of normal subjects, women have higher rates of CBF than men, and this is related to age. Usually by the sixth decade men and women have similar flow rates. Fewer studies on rCBF in schizophrenia have examined sex differences. The pattern of higher flows for females maintains, but its correlates with gender differences in clinical as well as other parameters of brain function remain to be examined.
神经行为学研究中已注意到性别差异。用于测量局部脑血流量（rCBF）的133氙吸入法有助于理解脑功能性别差异的神经基础。很少有研究探讨rCBF的性别差异。在对正常受试者的研究中，女性的脑血流量比男性高，且这与年龄有关。通常到第六个十年时，男性和女性的血流量相似。关于精神分裂症患者rCBF的研究中，较少有研究考察性别差异。女性较高血流量的模式依然存在，但其与临床以及脑功能其他参数中性别差异的相关性仍有待研究。
