title: [Circadian rhythm in the activity of adrenergic nerve fibers of the rat dura mater].
abstract: The Falk-Hillarp method was used to study the circadian rhythms of the activity of adrenergic nerve fibers of rat dura mater encephali. The adrenergic nerve apparatus has been characterized at varying times of the day both qualitatively and quantitatively. The period, fluctuation range and the magnitude of the activity rhythm of adrenergic nerve transmitters have been defined. The peak of the activity curve of adrenergic fibers has been fond to coincide with the activity peak at 12 o'clock. Different activity patterns of adrenergic nerve fibers correspond with different types of adrenergic function.
