Evoked activity (EA) of single neurons to verbal (or sensory) stimuli was recorded by microelectrodes in the nucleus reticularis and some other thalamic nuclei of the human brain during stereotaxic operations. An approach is considered which results from the assumptions of the cumulativeness and variability of the EA pattern and is based on the principal component analysis and peristimulus covariation matrices. Application of these methods for estimating unitary responses showed their efficiency for the quantitative analysis of the dynamic structure and interneuronal relations within the EA patterns during the performance of voluntary motor acts.
在立体定向手术过程中，用微电极记录了人脑网状核及其他一些丘脑核中单神经元对言语（或感觉）刺激的诱发活动（EA）。考虑了一种基于EA模式的累积性和可变性假设、并以主成分分析和刺激期协方差矩阵为基础的方法。应用这些方法估计单位反应，显示出它们在定量分析自愿运动行为执行过程中EA模式内的动态结构和神经元间关系方面的有效性。
