Hello, this is an upper-level question, and I would sincerely appreciate help before Tuesday.
I am reading a journal article, and there is one conclusion in it that I do not understand.
It predicts a postsynaptic mechanism when EPSP amplitudes do not vary across trials, and a presynaptic mechanism when EPSP amplitudes do vary across trials.
I don't understand how the variation is related to the pre/postsynaptic mechanism.
I appreciate your help and guidance. Thanks.
