A. decrs risk for seizures due to hypomagnesemia
B. Facilitation of Ca entry into the neuron and incrs of excitotoxin nediated cell death
c. hyperpolarization of membrane and conduction block
D. prevention of Ca entry into the neuron and reduction of excitotoxin mediated cell death
E. rapid depolarization of membrane w lowering of the seizure threshold.
