So perhaps I do not understand what you mean when you talk about a “negative action potential”
From my (admittedly rusty) neurobiology, synapses increase or decrease the likelihood of the next neuron reaching action potential and firing.
If the first neuron has a “positive” action potential and a depolarizing synapse… it will increase the likelihood of the next neuron firing (by the amount of weighting on the second neuron).
That should be fundamentally equivalent to the effect caused by a hypothetical “negative” action potential and a hyper-polarising synapse… and vice versa.
I think I my biology was more rusty than yours, I was confusing inhibitory postsynaptic potentials with “negative action potentials”. It looks like there is only one type of action potential coming out of a neuron along an axon, the positive/negative weighting occurs at synaptic junctions carrying over to integration on the dendrite.
That should be fundamentally equivalent to the effect caused by a hypothetical “negative” action potential and a hyper-polarising synapse… and vice versa.
Yes, that was what I was thinking when I (accidently) made up that term.
Ok.
