I learnt that two factors for NMDA receptor channels opening are:

1)Binding of glutamate

2)Depolarization of postsynaptic cell (to remove the Mg+2 block)

Given that depolarization starts in axon hillock and NMDA receptors are on dendrites, how does it all work?

  • $\begingroup$ "depolarization starts in axon hillock" - this is not true, why do you think this? $\endgroup$

  • $\begingroup$ Seemingly I confused the term with action potential. So NMDA receptors need a depolarization which is below +30? $\endgroup$

  • $\begingroup$ Yes, that's correct. Also read about backpropagating action potentials. $\endgroup$
