Researchers show how calcium ion-channels control arterial tone and blood flow in the brain.

Researchers have performed the first human-based study to identify calcium channels in cerebral arteries and determine the distinct role each channel plays in helping control blood flow to the brain. The study appears in The Journal of General Physiology. The team state that the contractile activity of smooth muscle cells in the walls of cerebral arteries determines the degree of
