Was unterscheidet ein AP von einem PSP?

Hallo,

wir sollen im Biologie-Unterricht über die Unterschiede zwischen einem Aktionspotential und einem Postsynaptischen Potential nachdenken, mir fällt da aber einfach nichts ein.

Ich wäre über gute Antworten sehr dankbar:)

The reactions of the receptors to a messenger lead to potential changes at the postynaptic cell (PSP). These individual changes must be emulated and overcrowded to trigger a new AP.

PSPs are therefore for the first time minor receptor responses to a messenger substance or a receptor-typical irritation.

Scroll down to comparison of AP and EPSP

What do you find cynical about it? I was pleasantly surprised that you can find the answer to this, but quite special question, on the Internet. I meant that very seriously and just as I wrote it: The internet is really the boar!

I remember the early times in the 1980s. At that time, I found the whole computer stuff quite superfluous for the average citizen and I always said at the time: once the “knowledge of the world” is accessible via the Internet, it becomes interesting to me. And I am still fascinated by the fact that this has occurred – and in my lifetimes! Even if not everything is available, rare notes e.g., you usually find on the Internet the indication in which library you can see them.

It’s a shame you misunderstood me.
