Single calcium channels in resistance-sized cerebral arteries from rats

Unitary currents through simple calcium channels were measured from cell-attached patches on smooth muscle cells isolated from resistance-sized branches of posterior cerebral arteries from normotensive rats. It was found that membrane depolarization decreased the longest mean closed time.
