Impedographic studies were made in cats made hydrocephalic by intracisternal kaolin. Enlargement of the anterior horns preceded that of the body of the lateral ventricles, and there was a selectivity to pressure atrophy among different tissues within the brain. Furthermore, sequential measurement of impedance using chronically implanted electrodes demonstrated a gradual decrease of impedance in the periventricular white matter during the development of hydrocephalus, suggesting an expansion of the extracellular space in the tissue around the ventricular wall.
对通过脑池内注入高岭土造成脑积水的猫进行了阻抗描记研究。前角的扩大先于侧脑室体部的扩大，并且脑内不同组织对压力性萎缩存在选择性。此外，使用长期植入电极对阻抗进行连续测量表明，在脑积水发展过程中，脑室周围白质的阻抗逐渐降低，这表明脑室壁周围组织的细胞外间隙扩大。
