Does NMDA-receptor activation depend on neighboring AMPA-receptor activity?

This question is coming out of a couple points of confusion after I learned about about NMDA receptors' role in LTP. I got the impression that after AMPA receptors were activated enough, which ...

How does the timing work out for dopamine to affect the development of long-term potentiation?

I just recently learned (indirectly from this source) that long-term potentiation/depression only takes place when you have large/small amounts of dopamine present at the relevant synapse. However, my ...
