...William I. Rosenblum Barium ion, applied as BaCl 2 to the cerebral surface, produces marked constriction of pial arterioles. The present data demonstrate that this constriction is inhibited by the calcium channel blockers verapamil and nimodipine. Verapamil in concentrations as low as 10–7 M...

.... Membrane potential measurements were made using intracellular microelectrodes. Depolarization with a high-potassium solution (K-PSS) elevated [Ca 2+ ] i and induced contraction. Further addition of 10 µ M noradrenaline (NA) did not elevate [Ca 2+ ] i further but enhanced tone. Addition of calcium channel...
