A postsynaptic neuron receives four signals simultaneously that create four postsynaptic potentials.  There are EPSPs that depolarize the membrane at the trigger zone: EPSP#1= +3mV, EPSP#2= +9mV, EPSP#3= +13mV.  The last one is an IPSP that hyperpolarizes the membrane: IPSP= -10mV.  Based on these four incoming signals, would this postsynaptic neuron be capable of making an action potential (assume threshold is reached if net depolarization is sufficient)?
