Fig. 5From: Attenuated Ca2+ release in a mouse model of limb girdle muscular dystrophy 2AElectrical activity of WT and C3KO fibers in response to tetanic stimulation. a Mean amplitude (±SEM) of the first and last action potentials recorded from WT (n = 14) and C3KO fibers (n = 18) stimulated at 10, 20, 50, and 100 Hz. b Mean depolarization (±SEM) measured in WT and C3KO fibers at the end of trains of stimulation at 10, 20, 50, and 100 Hz. The inset demonstrates how the amplitude of the first and last action potentials and depolarization were measured in a record obtained in a C3KO fiber stimulated with a 100-Hz train of pulses (1 s). Asterisks indicate statistical significance (p < 0.05)Back to article page
