Postsynaptic potential function (PSP) with weight dependency. (A) Red line is for ω=1, green for ω=−1 and blue is for ω=0.5. (B) Two neurons (yellow) generate spikes, which are presynaptic for next layer neuron (green). (C) Membrane potential graph for green neuron. Presynaptic spikes raise the potential; when the potential is above threshold, a postsynaptic spike is generated and the neuron becomes overpolarized.
