Okay, so we're looking at the events of synaptic transmission.
00:07
So between the synapses, let's say this is the, over here we have the pre -synaptic membrane, and over here we have the post -synaptic membrane, and in between here is the synaptic cleft.
00:25
Okay, so we're given that first the impulse reaches the synapse.
00:31
That impulse is going to cause a change in membrane potential.
00:37
Outside of the membrane, there's all of these calcium ions.
00:42
And that change in membrane potential is going to cause all of those calcium ions to move inside of the cell.
00:50
That's going to be the influx of calcium ions.
00:55
So that gives us number two, change in membrane potential.
01:02
Causes influx of calcium, that calcium moving into the cell is going to make these, we'll put them in blue, these synaptic vesicles move to the presynaptic membrane...
