[The methodology on the study of blink reflex and its normative parameters]

The study of blink reflex is a modern and high informative method of electroneurophysiological diagnosis. The data of clinical studies are controversial that confirm the actuality of the problem and indicate the necessity of universal approaches to methodology and interpretation of obtained results. We studied peculiarities of reflex electromyographic (EMG) components of blink reflex of the circular eye muscle during the electric stimulation of the supraorbital nerve in 31 healthy people. The latency of R1 and R2 components, amplitude of R1-component, square of general power spectrum of EMG-discharge, making up the R2 component, duration of R2-component and latency of R3-component, in case of its presence, have been estimated.
