How much is the time gap between a intrinsic action potential and a postsynaptic potential?

Hi everyone for example, there are two neurons. One is presynaptic neuron (neuron A) and one is postsynaptic neuron (neuron B), which means they are mono synaptically connected and no feedback...

Can I say both LTP and LTD depend on influx Ca2+, but the amount of delta[Ca2+]i leads to different results?

It is very helpful to me if anything I wrote is wrong is pointed out. In this way I can learn more or correct what I knew. Many thanks. As far as I understand, LTD is Ca2+ influx but activates...

Is it possible for two human neuronal cell lines to have different gene sequence for the same protein?

I am looking at the ATP1A2 (Sodium/Potassium ATPase alpha subunit 2) in two human neuronal cell lines. Expression levels of this protein seems to be almost equal when detected by one antibody....
