在生理学实验及临床实践中,肢体容积描记法被广泛用作为研究血管运动机能的一种手段,有不少学者还通过对血管的条件及非条件反射活动的分析来了解机体的高级神经活动特性。但用一般的容积描记器所记录到的肢体容积描记图本身,究竟反映了那些血管的活动?它们与血管运动中枢的机能以及与高级神经活 Physiological experiments and clinical practice, limb plethysmography is widely used as a means of studying the motor function of blood vessels, many scholars also through the analysis of vascular conditions and unconditional reflex activity to understand the body’s advanced neural activity characteristics . However, the body plethysmography recorded by a typical plethysmograph itself reflects the activity of those vessels, their function with the vasomotor center,
