c. reduced blood flow ->activation of Na+/K+ transporters -> membrane hyperpolarization -> DA release -> excessive accumulation of intracellular CL-
d. reduced blood flow -> inactivation of Na+/K+ transporters -> membrane hyperpolarization - > GABA release -> excessive accumulation of intracellular CA++
