3. Specifically, a molecule of the neurotransmitter receptor. But, the magnesium (Mg+) ion is blocking the ion channel, so Ca+ ions cannot enter. However, if that postsynaptic neuron fires, the Mg+ ion will be ejected. binds to an NMDA This allows ions to flow into the postsynaptic neuron. When these ions flow into the postsynaptic neuron, they cause receptors to move to the dendritic spines on the postsynaptic neurons. With a surplus of these receptors, Na+ ions can more easily flow into the postsynaptic neuron. The influx of Na+ ions cause the postsynaptic neuron to depolarize.
