You are examining a postsynaptic neuron that has a resting membrane potential of -70 mV and a threshold of -55 mV. If an inhibitory presynaptic neuron creates an IPSP of -5 mV and two excitatory presynaptic neurons have EPSPS of 10 and 12 mV, will the postsynaptic neuron fire an action potential if all three pre- synaptic neurons fire at the same time? In your answer describe EPSPS, IPSPs, emporal or spatial summation as appropriate.
