title: [A dynamic study of the impulse processes in human cerebral neurons by using the principal-component method].
abstract: 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.
