Fine spontaneous contractions of the arterial wall of the rat in vitro.
Fine spontaneous contractions of the vascular wall were recorded from the isolated carotid artery of the rat. The amplitude and/or frequency of these fine contractions decreased in lower temperature and increased in norepinephrine. It was suggested that there is an important relationship between these fine contractions and vascular "tone" of the artery.
