A cell receives two synaptic inputs at adjacent locations on a dendritic branch. Each synapse, when activated by a single pre-synaptic spike, produces a depolarizing EPSP. From resting potential, these EPSPs create a peak voltage change of +18 mV. If the resting potential is -80 mV and threshold for spike generation is -40 mV, can these two synapses ever cause a spike in the post-synaptic cell? Explain.
