abstract：:An increase in free Ca2+ triggers exocytosis in pituitary nerve terminals leading to an increase in membrane area and membrane capacitance. When Ca2+ is increased by step depolarization, an instantaneous capacitance increase during the first 80 ms is followed by a slow increase extending over several seconds. We measu...
