Hi all ..

Can someone please explain what these things are, when recording
from brain areas? I know they have something to do with neurons'
action potentials, but not exactly what they are. The books I've
read try to explain them in too-complicated fashion for a beginner.
I'm writing a literature review of long-term potentiation in the
hippocampus (for an assignment), and they use these measures to
assess enhanced synaptic efficacy.

Thanks for the help!
