A neuron with a resting membrane potential of -75 mV receives multiple inputs giving rise to the following post-synaptic potentials: -15 mV, 20 mV, -5 mV, 7 mV, and 22 mV. The threshold is -50 mV. What will be the outcome? O a. An action potential (AP) will be generated because there are more positive than negative inputs o b. No action potential because the presence of a single IPSP is sufficient to prevent an AP An action potential (AP) will be generated because the sum exceeds the threshold o d. An action potential (AP) will be generated because the sum of inputs is a positive value o e. No action potential (AP) will be generated because the sum of inputs is below the threshold
