Withdrawal-related seizures characterized as generalized tonic-clonic convulsions as well as alcoholic hallucinosis or hallucinations related to abrupt alcohol cessation may occur in moderately severe cases.

lisabon 2012 [21]

The answer is; Sodium (Na+) and Potassium (K+) Ions


These cations are pumped out of the cell by Na+-K+ transmembrane protein pumps leaving the inside of the cell electronegative in relation to the extracellular matrix. This membrane potential is significant especially for neurons. Depolarization of the membrane enables transmissions of an impulse along the neurons.
