An initial test for a theory of lateral hypothalamic regulation of electrocortical activity is undertaken. The theory supposes lateral hypothalamic input directly or indirectly damps telencephalic resonances involving linear wave phenomena, enabling this pathway to act as parametric control of information processing in cortical neural networks. Relative changes in left and right electrocortical power spectra are used to test for the presence of resonant modes with constant natural frequencies in conditions of asymmetrical damping, following unilateral lesion of the lateral hypothalamus. Natural frequency values for the modes clustered about center frequencies in the EEG band are obtained. This method has the advantage of minimising the effects of time-variation and the recorded signal's distortion from the electrocortical local spatial average, but limits consideration to five dominant modes of resonance. The uncertainty of true model order, and errors in curve-fitting impose limitations on the test.
对下丘脑外侧对皮层电活动调节理论进行了初步测试。该理论认为，下丘脑外侧输入直接或间接抑制涉及线性波现象的端脑共振，使该通路能够作为皮层神经网络中信息处理的参数控制。在单侧下丘脑外侧损伤后，利用左右皮层电功率谱的相对变化来测试在不对称阻尼条件下具有恒定固有频率的共振模式的存在。获得了聚集在脑电图频段中心频率附近的模式的固有频率值。该方法具有将时间变化和记录信号从皮层局部空间平均值的失真影响降至最低的优点，但将考虑限制在五个主要共振模式。真实模型阶数的不确定性以及曲线拟合中的误差对测试施加了限制。
