A second test is undertaken for a theory of linear wave motion in electrocortical waves, under lateral hypothalamic control via regulation of damping. This test invokes a general property of linear systems, namely that wave motion with characteristic natural frequencies implies fixed phase velocities associated with each wavelength, independent of the changes in hypothalamic input. A means of testing the invariance of this dispersion relation at the point of recording is derived from a simplified biophysical model for waves in a dipole layer. The method avoids some problems implicit in direct spatio-temporal wave analysis. Results confirm that the model under test is internally consistent, and is also consistent with other findings concerning the origin and spatial nature of the EEG.
针对电皮层波的线性波动理论进行了第二项测试，该理论受下丘脑外侧通过调节阻尼进行控制。此测试援引了线性系统的一个普遍特性，即具有特征固有频率的波动意味着与每个波长相关的固定相速度，与下丘脑输入的变化无关。从偶极层中波的简化生物物理模型推导出一种在记录点测试这种色散关系不变性的方法。该方法避免了直接时空波分析中隐含的一些问题。结果证实，被测模型在内部是一致的，并且也与关于脑电图起源和空间性质的其他发现一致。
