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.

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.
