title: [Relationship between electrical activities of different areas of the myometrium in rats].
abstract: The work is dedicated to the study of the influence of separate rhythmogenic areas on spontaneous activity of the remained areas in the non-pregnant rat myometrium. The main characteristics of pacemaker activity (spike frequency, spike amplitude, duration of burst discharges, summarized period of the active state) of each active region were analyzed under the conditions blocking the influence of others. Parameters of the ovarian horn area did not undergo significant changes unlike the cervical horn area and uterine corpus. The greatest suppression of spike activity parameters was shown in the uterine corpus. It was also revealed that certain activity characteristics (the amplitude of the spikes, duration of burst discharges, summarized period of the active state) are more subjected to change than other parameters. It is concluded that the ovarian horn area may have a controlling role in the interaction of asynchronous pacemaker activities of the rhythmogenic areas in the uterus.
