WebAlcohol works in a “double-duty” fashion. It can bind to GABA receptors to hold the ion channel open longer. This increases the amount of chloride ions (negative charges) entering the neuron (Figure 2.5). Also, alcohol can bind to glutamate receptors, where it decreases the amount of sodium and calcium (positive charges) entering the neuron.
