title: [The correlation of the bioelectrical activity of the archistriatum and the neck muscles of chickens in ontogeny].
abstract: Experiments have been carried out on 14-, 18-day chick embryos and 1-day chicks. Studies were made on amplitude-frequency, temporal, integral parameters of EEG in archistriatum and EMG in neck muscles, as well as on their crosscorrelation. It was shown that archistriatum EEG may be recorded from the 14th day of incubation. From the 14th to the 18th day, rapid changes in the frequency were observed, from the 18th day--in the amplitude. EMG had a pattern of bursts of the bioelectrical activity which consists of both high and low amplitude action potentials. Between the 14th and the 18th day of incubation, more significant changes were observed in the duration of these bursts, after the 18th day--in the interval between the latter. Reliable correlation between the integral parameters of EEG in archistriatum and EMG in neck muscle was found in 18-day chick embryos and 1-day chicks. Bilateral coagulation of archistriatum resulted in significant increase in total bioelectrical activity of the muscle.
