The NMDA receptor is an ion channel and contributes to synaptic plasticity and memory. It is said that calcium ion flux through the receptor is critical for this mechanism. However, there are other ion channels that let calcium ions into the cell, how come they don't contribute to synaptic plasticity (to my knowledge)?

    $\begingroup$ It is not just an ion channel. The name itself suggests that it is a receptor i.e. it responds to a ligand. Perhaps you can read a tiny bit more about NMDA receptor and the answer would become obvious. $\endgroup$ – WYSIWYG Mar 7 at 15:53
